Fix broken activation of the selected view in accessibility mode.
We were using an approximation to determine where to send a pair of down
and up events to click on the view that has accessibility focus. We were
doing reverse computation to figuring out which portion of the view is
not covered by interactive views and get a point in this region. However,
determining whether a view is interactive is not feasible in general since
for example may override onTouchEvent. This results in views not being
activated or which is worse wrong views being activated.
This change swithes to a new approach to activate views in accessibility
mode which is guaranteed to always work except the very rare case of a
view that overrides dispatchTouchEvent (which developers shouldn't be
doing). The new approach is to flag the down and up events pair sent
by the touch explorer as targeting the accessibility focused view. Such
events are dispatched such that views predecessors of the accessibility
focus do not handle them guaranteeing that these events reach the accessibiliy
focused view. Once the accessibiliy focused view gets such an event it clears
the flag and the event is dispatched following the normal event dispatch
semantics.
The new approach is semantically equivalent to requesting the view to perform
a click accessiblitiy action but is more generic as it is not affected by
views not implementing click action support correctly.

Accessibility: Sometimes cannot interact with nav bar items.
If there is a window with the accessibility focus we want to click
on the accessibility focused view in this window. The logic to
compute the bounds of the window was using the wrong window id,
hence getting an incorrect result. As a consequence in some cases
the user could not click on accessiiblity focused controls in the
nav bar.

Ignore accessibility overlay when computing window's interactive region.
If an accessibility service opts-in for the new window introspection APIs
when calling into a window for accessibility node infos we compute the
window's interactive region, i.e. the portion that is touchable and not
covered by other touchable windows, in roder to deterine whether these
nodes are visible, i.e. the user can interact with them. There was a bug
in the interactive region computation what we were not ignoring accessibility
overlay windows which are intended to not change what an accessibility
service can "see" and are put by such a service.

Accessibility services may opt-in to introspect the interactive
windows on the screen. If window introspection is enabled there
is a case where some events from a showing window are received
before the updated window state from the window manager. Now the
window manager sends over the windows before notifying the app
for the focus change.

APIs for an accessibility service to put interaction tracking overlays.
An accessibility service may register to observe the interactive windows
on the primary display. These windows are the one that has input focus and
ones a sighted user can touch. It is sometimes beneficial for an
accessibility service to overlay a window to intercept user interaction
and based on that introspect and perform an action on the windows that
are on the screen. This is problematic as overlaying a full screen window
that is touchable prevents the accessibility service to introspect the
content under this window.
This change adds a special type of window that only an accessibility service
can place which does not affect what an accessibility service can "see" on
the screen. Hence, even putting such a window full screen the service will
be able to interact with the other interactive windows it covers.

Send accessibility events with no window.
An app can send an accessibility event by calling the send methods
on view or directly asking the accessibility manager to do that.
While the recommened way to send such events is calling the methods
on view a legacy app or app whose developer did not read the docs
carefully may be calling the accessibility manager APIs directly.
In such a case the event does not have assigned window id and does
not get send. Since events fired by using the accessibility manager
directly lack context to determine whether thier source is important
for accessibility we assume they come from an important view to
avoid breaking backwards compatibility.

Fix accessiblity introspection from the shell user regression.
Accessibility introspection APIs are meant to query only the state of
the current user. There are command line tools that run as the shell
user and want to be able to intropspect the screen. When resolving
the calling user we were using the calling user id instead of the
special constant for the current user.
Now when resolving the calling user for intrspection we are using
the current user constant and consequentially only the current
user or a profile of the current user or the root or the shell or
the system or an app with cross user permission can introspect the
screen.

Invalid active window if temporary disabling accessibility for test tools.
If accessibility is enabled and a test tool based on the accessibility APIs
connects to the system we suspend the current accessibility services while
the tool is running (to avoid inteference as the tool is such a service) and
after the tool disconnects we restore the accessibility state. The issue is
that when clearing the accessibility state we were also wrongly clearing the
active window. We are now careful to not clear the active window in such a
case.
It is also possible that the active window was never initilaized before the
tool is run so now it is lazily loaded such that if we do not know which one
it is, we get the one the has input focus. The definition of an active window
is the one that has input focus or the user is touching.

Accessibility events may be fired even if no services observe them.
If all accessibility services are disabled we turn off event firing
to avoid a lot of work for nothing. The logic to do that had a flaw
and was not turning event firing off in every case it should. We were
tuning event firing if it is on and no service is enabled but it
is possible that a package on the system image is disabled so the
service is enabled just not bound. Arguably we can remove the
serivice from the enabled list but it is technically on the device.
Note that we correctly handle the case of a package being removed.

Some accessibility events wrongly filtered out (regression).
We added new APIs to allow accessibility services to query all
windows a user can touch. Sometimes the window state change
event arrives before the window manager sent over the new window
state which leads to a case that the app gets the event and
asks for the window and the window is not there. To address this
if we do not have the window, we hold on to the event and
fire it as soon as the window arrives. This logic is correct
except we were wrongly expecting that the window should have
input focus.

Clicking on partially coverd views by other views or windows.
In touch exploration mode an accessibility service can move
accessibility focus in response to user gestures. In this case
when the user double-taps the system is sending down and up
events at the center of the acessibility focused view. This
works fine until the clicked view's center is covered by another
clickable view. In such a scenario the user thinks he is clicking
on one view but the click is handled by another. Terrible.
This change solves the problem of clicking on the wrong view
and also solves the problem of clicking on the wrong window.
The key idea is that when the system detects a double tap or
a double tap and hold it asks the accessibility focused node
(if such) to compute a point at which a click can be performed.
In respinse to that the node is asking the source view to
compute this.
If a view is partially covered by siblings or siblings of
predecessors that are clickable, the click point will be
properly computed to ensure the click occurs on the desired
view. The click point is also bounded in the interactive
part of the host window.
The current approach has rare edge cases that may produce false
positives or false negatives. For example, a portion of the
view may be covered by an interactive descendant of a
predecessor, which we do not compute (we check only siblings of
predecessors). Also a view may be handling raw touch events
instead of registering click listeners, which we cannot compute.
Despite these limitations this approach will work most of the
time and it is a huge improvement over just blindly sending
the down and up events in the center of the view.
Note that the additional computational complexity is incurred
only when the user wants to click on the accessibility focused
view which is very a rare event and this is a good tradeoff.

Fix AccessibilityNode's isVisibleToUser behavior.
The isVisibleToUser property of an AccessibilityNodeInfo specifies
whether the user can see the source view. It is used by accessibility
services to figure out whether to focus on a view. This property
was giving a wrong value if the view is covered by another window
such as the keyboard. As a result the user hears one thing but when
double taps interacts with the overlaid window which is another thing.

Fix accessiblity CTS tests (framework).
1. An external contribution changed the ordering of views for
accessibility. While it attempted to fix a platform issue
for a comparator breaking transitivity, it changed the way
we order views and results in very unnatural accessibility
traversal order. It also broke CTS tets. This change tweaks
the comparator which fixes the tests and improves traversal
order.
2. If there is at least one accessibility service which cares
about windows we register a callback in the window manager
for window change notifications. We are updating the window
list on this callback. There was a case where if the service
requests window updates and immediately asks for the windows
it gets none as we have not received a callback from the
window manager yet. Now this call returns after we get the
callback in a timed fashion. This is consistent with how the
other introspection APIs work.
3. Window info objects are cached in the accessibility service
process. When putting them in the cache a cloning call was
missing resulting in some cases of clobbering windows given
to the client. For example, we get some windows, cache them,
and return these windows to the client. Now a call to clear
the cache arrives while the user processes the windows and
the client windows get clobbered.
4. Added API for checking if a window has accessiblity focus
to be consistent to the API we have to check whether this
window has input focus.
5. Removed some obsolete code.

Improve the window query API performamce.
We are caching the window data in the accessibility service process.
When windows change we were sending the dalta of the windows the
service knows about. To make this work when the app asked for all
windows we had to call into the system as new windows may have
appeared. This was slow.
Now we are telling the service some windows change and if it gets
the windows we cache them. We call into the system only on a cache
miss and evict all windows from the cache on window change event.
We do not evict the nodes of the window as the former may have
just moved. If views in a window change they fire accessibility
events that trigger the correct eviction.

Add accessibility text contrast setting
b/14624452
Adds a feature which draws all text (in the HW accelerated standard
path) in a high contrast mode. Text is drawn at full alpha, and either
white or black (depending on its original color) with a starkly
contrasted outline beneath it.

Fix backwards compatibility for introspected windows.
1. The APIs for introspecting interactive windows were reporting only
the touchable windows but were missing the focused window. The user
can interact with the latter by typing, hence it should always be
reported. Also this was breaking backwards compatibility as if the
focused window is covered by a modal one, the focused window was not
reporeted and this was putting the active window in a bad state as
the latter is either the focused window or the one the user is touching.
2. Window change events are too frequent as on window transition things
are chanign a lot. Now we are trottling the windows changed events
at the standard recurring accessibility event interval.
3. Fixed a wrong flag comparison and removed some unneded code.

Fixing bugs due to the new custom accessibility action APIs.
1. AccessibiltiyAction was incorectly throwing an exception when
a custom action was constructed.
2. AccessibilityManagerService should no longer enforce only standard
actions as we allow custom ones too.

Teach accessibility manager services about user profiles.
For user profiles the accessibility layer will use the accessibility
state of the their owner. A profile cannot have its own plugins or
settings. The rationale behind this is that if a user with impaired
vision is using the device with different profiles linked to his
main one, then he/she should be able to interact with the device no
matter what profile the app is being run with. Hence, The behavior
of the accessibility features should be consistent across apps run
with different profile.

Adding system support for a single accessibility focus.
Now that we have APIs to query all interactive windows and allow
an accessibility service to put accessibility focus in each of
them we have to guarantee that there is a single accessibility
focus. This is required for correct operation of the touch
explorer as on double tap in clicks in the center of the focused
area, hence having more that one focus is an issue. Also the
system is maintaining a single input focus so now accessibility
focus behaves consistently with that.

Make Keyguard a library and make StatusBar the new Keyguard.
This change achieves a couple of things:
- Let Keyguard be a library, so we can use it in SystemUI.
- Introduce FLAG_KEYGUARD for windows and deprecate TYPE_KEYGUARD. Make
all the TYPE_KEYGUARD behaviour dependant on the flag.
- Implement a new KeyguardService in SystemUI, and bind that service
from PhoneWindowManager.
- Introduce BaseStatusBar.setKeyguardState and inflate
KeyguardSimpleHostView there and use FLAG_KEYGUARD for the window, such
that the status bar window essentially gets the Keyguard.

Added accessibility APIs for introspecting interactive windows.
1. The old introspection model was allowing querying only the active window
which is the one the user is touching or the focused one if no window is
touched. This was limiting as auto completion drop downs were not inspectable,
there was not way to know when the IME toggles, non-focusable windows were
not inspectable if the user taps them as until a screen-reader starts
introspecting the users finger is up, accessibility focus was limited to
only one window and the user couldn't use gestures to visit the whole UI,
and other things I can't remember right now.
The new APIs allow getting all interactive windows, i.e. ones that a
sighted user can interact with. This prevents an accessibility service
from interacting with content a sighter user cannot. The list of windows
can be obtained from an accessibility service or the host window from an
accessibility node info. Introspecting windows obey the same rules for
introspecting node, i.e. the service has to declare this capability
in its manifest.
When some windows change accessibility services receive a new type
of event. Initially the types of windows is very limited. We provide
the bounds in screen, layer, and some other properties which are
enough for a client to determined the spacial and hierarchical
relationship of the windows.
2. Update the documentation in AccessibilityService for newer event types.
3. LongArray was not removing elements properly.
4. Composite accessibility node ids were not properly constructed as they
are composed of two ints, each taking 32 bits. However, the values for
undefined were -1 so composing a 64 long from -1, -1 prevents from getting
back these values when unpacking.
5. Some apps were generating inconsistent AccessibilityNodeInfo tree. Added
a check that enforces such trees to be well formed on dev builds.
6. Removed an necessary code for piping the touch exploration state to
the policy as it should just use the AccessibilityManager from context.
7. When view's visibility changed it was not firing an event to notify
clients it disappeared/appeared. Also ViewGroup was sending accessibility
events for changes if the view is included for accessibility but this is
wrong as there may be a service that want all nodes, hence events from them.
The accessibility manager service takes care of delivering events from
not important for accessibility nodes only to services that want such.
8. Several places were asking for prefetching of sibling but not predecessor
nodes which resulted in prefetching of unconnected subtrees.
9. The local AccessibilityManager implementation was relying on the backing
service being ready when it is created but it can be fetched from a context
before that. If that happens the local manager was in a broken state forever.
Now it is more robust and starts working properly once the backing service
is up. Several places were lacking locking.
