Prevent WebView from crashing when detached from the window
Bug #6365056
WebView enqueues a functor in the hardware renderer to handle
animations and this functor is called at a later time by the
hardware renderer. However, the functor was not removed from
the queue when WebView was removed from the window. This could
cause the hardware renderer to attempt to execute an invalid
functor and lead to a crash.

Improve MessageQueue sync barrier implementation.
Instead of acquiring and releasing a barrier using an up/down
counter, we post a message to the queue that represents the
barrier. This is a more natural representation of the barrier
and better matches what we want to do with it: stall messages
behind the barrier in the queue while allowing messages earlier
in the queue to run as usual.
Refactored the MessageQueue a little bit to simplify the quit
logic and to better encapsulate the invariant that all
messages within the queue must have a valid target. Messages
without targets are used to represent barriers.

Add a barrier mechanism to the MessageQueue.
The synchronization barrier enables selectively blocking
execution of synchronous messages until the barrier is released.
Asynchronous messages may continue running in the meantime.
The barrier is intended to be used to implement more sophisticated
scheduling policies related to view hierarchy traversals. While
traversals are pending, most messages posted to the message queue
must be held up. This is to satisfy the invariant that traversals
will occur before subsequently posted messages are handled.
The exception to this rule are "asynchronous" messages that represent
external events or interrupts that come from other components such
as VSYNC pulses, input events or sensor events. Because these messages
are typically delivered at arbitrary times, they are independent of
traversals or other typical synchronization boundaries.
Messages can now be flagged as asynchronous to indicate that they
are weakly ordered.

Switch Looper back to using poll() instead of epoll().
Added a couple of micro-optimizations to avoid calling wake() unnecessarily
and reduce JNI overhead slightly.
Fixed a minor issue where we were not clearing the "next" field of Messages
returned by the MessageQueue so the Message would hold on to its successor
and potentially prevent the GC from collecting it if the message were leaked
somehow.

Simplify and optimize MessageQueue loop.
Avoids allocating new idle handler arrays on each iteration since
we only need one to copy into.
Coalesced the synchronized blocks.
Hoisted the call to Binder.flushPendingCommands() outside of the
synchronized block.

Input dispatcher ANR handling enhancements.
This change is essentially a rewrite of the main input dispatcher loop
with the target identification folded in. Since the input dispatcher now
has all of the window state, it can make better decisions about
when to ANR.
Added a .5 second deadline for processing app switch keys. This behavior
predates Gingerbread but had not previously been ported.
Fixed some timing inaccuracies in the ANR accounting that could cause
applications to ANR sooner than they should have.
Added a mechanism for tracking key and motion events that have been
dispatched to a window so that appropriate cancelation events can be
synthesized when recovering from ANR. This change helps to keep
applications in sync so they don't end up with stuck buttons upon
recovery from ANRs.
Added more comments to describe the tricky parts of PollLoop.

Allow reliable detection of a message that is in use.
Because the standard Looper.loop code calls Message#recycle it is
imperative that Handler#handleMessage code not attempt to resue
a message it receives. If allowed to do so it will cause bugs that
could be difficult to diagnois.
This change adds Message#flags and uses one bit to reliably detect
a message is in use and throws an error in MessageQueue#enqueueMessage.
This allows early detection of this bug.
Note: This is not new functionality, but the current implementation does
not detect messages that are in use because it uses Message#when != 0
as the detection mechanism. The problem is that a Message#when value of 0
is valid value used to place a message at the front of the queue and is
thus unreliable.
Another option is to change the setting of Message#when in Message#enqueueMessage
so that it is never 0, although that does change subtly a publicly accessible
field.
Yet another option would be to use other fields but all candidates have
similar problems as when in that they are publicly accessible or even
settable such as Message#target.

Revert "Allow reliable detection of a message that is in use."
This reverts commit 6083d81ce4d67ec632962270fda64ebb9db0d5b1.
Reverting this because it causes runtime to reboot in a loop
if connected to a Bluetooth Headset.
copyFrom() needs to check for the introduced bit too.

Native input dispatch rewrite work in progress.
The old dispatch mechanism has been left in place and continues to
be used by default for now. To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.
Includes part of the new input event NDK API. Some details TBD.
To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument. The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points. The ViewRoot then
provides the InputChannel to the InputQueue. Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue. This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.
There can be zero or more targets for any given input event. Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets). Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.
End-to-end event dispatch mostly works!
To do: event injection, rate limiting, ANRs, testing, optimization, etc.

Sketch of Native input for MessageQueue / Looper / ViewRoot
MessageQueue now uses a socket for internal signalling, and is prepared
to also handle any number of event input pipes, once the plumbing is
set up with ViewRoot / Looper to tell it about them as appropriate.

DropBox logging of app & system server crashes.
The crashes are also reported to the event log (and of course the
main logcat, like they always have been). Ordinary Log.e(t,m,e) isn't dropboxed
but there's a new Log.wtf() which always is. (Still @pending in this change.)
Add a hook to IPowerManager to crash the system server on demand
(only for apps with REBOOT permission, since it's basically a restart).
This is not exposed in PowerManager, must be invoked directly -- mostly
this is there so "Bad Behavior" in dev tools can do it.
