Use structural equality for A11yNodeInfo#mChildNodeIds
This reintroduces I508df9e4346e304b8ae56cc38b17e9a940d941f1
with the addition of missing nullchecks
A11yNodeInfo#writeToParcel relied on LongArray#equals to avoid
storing it if it's the default value, but because the equality
is be by reference, it would store it every time.
This fixes that.
Test: a11y cts

Improve utility of IntArray and LongArray
This patch adds several utility methods to IntArray and LongArray to
make them more useful in the context of a Parcelable class.
More specifically, it is now possible to parcel and unparcel a
{Int, Long}Array with the following one liners:
- mIntArray = IntArray.wrap(parcel.createIntArray());
- parcel.writeIntArray(mIntArray.toArray());
This patch also
- adds unit tests for IntArray and LongArray.
- adds a method for setting a field at a given index.
- adds a method for changing the effective array length.
- adds missing bound checks for negative index values.
Test: added test coverage

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.
