InputChannels are normally duplicated when sent to a remote process
over Binder but this does not happen if the recipient is running within
the system server process. This causes problems for KeyGuard because the
InputMethodManagerService may accidentally dispose the channel
that KeyGuard is using.
Fixed the lifecycle of InputChannels that are managed by the IME
framework. We now return a duplicate of the channel to the application
and then take care to dispose of the duplicate when necessary.
In particular, InputBindResult disposes its InputChannel automatically
when returned through Binder (using PARCELABLE_WRITE_RETURN_VALUE).

The input method manager service now supplies an input channel for
communication while creating an IME session on behalf of the
application.
This change significanly reduces the overhead of IME event dispatch
by using a standard input channel to send input events rather than
using binder. This results in fewer thread context switches
and fewer object allocations.
What's more, the IME may perform additional batching of the motion
events that it receives which may help it catch up if it is
getting behind while processing them.

8323587: Add feature for supporting app widgets
8323342: Add feature for replacing the home screen
8323590: Add feature for supporting input methods
The app widget service looks for the app widget feature
and refuses to work if it doesn't exist. I didn't do
this for the input method service because some devices
will probably want to still make use of that mechanism
without supporting third party input methods.

BadTokenException is a normal consequence of swapping IMEs while there
is a DO_SHOW_SOFT_INPUT message in the IIMethodWrapper queue. This
race condition cannot be avoided without an unacceptable lock down of
InputMethodManagerService.

When a new IME is attached it is not enough to remove the
WindowManager messages from the local queue, but the ones in
the previous IME queue must also be removed.

The disabled state allows you to make an app disabled
except for whatever parts of the system still want to
provide access to them and automatically enable them
if the user want to use it.
Currently the input method manager service is the only
part of the system that supports this, so you can put
an IME in this state and it will generally look disabled
but still be available in the IME list and once selected
switched to the enabled state.

This is a serious issue which the disabled system auxilialy IME is unexpectedly re-enabled by re-building internal IMI cache.

Improves the throughput of IME event handling by ensuring that
input events do not get serialized behind UI traversal and
drawing messages such as when the UI is animating.
Added support for creating an asynchronous Handler as part of a
HandlerCaller. It turns out we should be using an asynchronous
Handler not only in IME dispatch but also in accessibility and
wallpaper events where HandlerCaller is used. So fixed those
services to also use an asynchronous Handler.

The input method manager service now keeps track of whether or not
the ime was shown on the keyguard. This prevents activities behind
the keyguard from incorrectly showing the down-caret in the keyguard.

The gnarly stuff where we keep track of the old input method
window as if it was still there was sitting around leaving things
in a stuck state. Now we clear this out at key points in the
window manager (freezing screen, user change), and the input
method manager service is less aggressive about asking the window
manager to do it.
Also fixed a problem that was causing flickers during some
wallpaper transitions -- when we are animating two things on
top of the wallpaper and one of them disappears, we need to
make sure the wallpaper target points to whatever the current
target should be (if any), not left pointing to the old target
that has gone away.

Bug: 7368245
Log a warning if the system process calls unqualified sendBroadcast()
and other calls.
As a result of the logging above, found a few more method calls such as
bindService() that would benefit from being more explicit to avoid
future confusion and reduce the log warnings.

1.If a window is shown but never moved the window window
is never notified for its current location. Therefore,
accessibility nodes do not contain correct bounds in
screen coordinates.
