The problem was:
1. In handleShutter(), thread A in CameraService calls
registerBuffers(IMemoryHeap) and it's received by thread B
in system_server. [transaction 1]
2. While thread A is waiting for the reply, thread B calls
back to thread A to get the id of the heap
(IMemoryHeap.getHeapID). [transaction 2]
3. Thread A replies transaction 2 and is preemptied in kernel.
Thread B gets the reply and finishes registerBuffers and send
reply for transaction 1.
4. When thread A runs again, it gets the reply for transaction 1
and returns to handleShutter().
5. At this point the transaction buffer for transaction 2 (which
holds a reference to IMemoryHeap) is not freed because the
BC_FREE_BUFFER command is kept in thread A's local command
queue and not sent to the kernel.
6. Normally when thread A makes next transaction, the
BC_FREE_BUFFER command will be sent together (piggyback) with
the commands for that transaction. But in this case thread A
is a callback thread from camera driver, so it does not make
any binder calls afterwards, and the IMemoryHeap is never freed
(until the next time handleShutter is called).

Fix issue 2811538: System server crash when disconnecting BT headset after using SCO off call.
On omap3 h/w we force opaque formats to RGB_565 instead of RGBX_8888
because the GL driver doesn't support it. RGBX_8888 is always remapped
to RGBA_8888.

Not yet hooked up to anything in the NDK, but requires renaming
the existing android_native_window_t type everywhere.

This change mainly unwinds a premature optimization in the
dispatch pipeline.
To test HOME injection, run 'adb shell input keyevent 3'.

Verify hostname where possible, and clarify where not.
The native code now maintains a list of all keys that may use
default handling. If the app finishes one of these keys
without handling it, the key will be passed back off to Java
for default treatment.

docs: revise menu guide to focus more on using menu resources
Set a default orientation of ROTATION_0.
Added some more careful checks based on whether we have valid
absolute axis information from the driver.
Reset key repeating during configuration changes since the keyboard
device may have been removed.

Fixed a typo where checking against the wrong constant caused GL_TEXTURE_EXTERNAL_OES
to be used with a regular texture, which some GL driver will choke on.

Target identification is now fully native.
Fixed a couple of minor issues related to input injection.
Native input enabled by default, can be disabled by setting
WindowManagerPolicy.ENABLE_NATIVE_INPUT_DISPATCH to false.

Effect API:
- Use different definitions for audio device, channels, formats... in AudioSystem and EffectApi:
Removed media/AudioCommon.h file created for initial version of EffectApi
- Indicate audio session and output ID to effect library when calling EffectCreate(). Session ID can be useful to optimize
the implementation of effect chains in the same audio session. Output ID can be used for effects implemented in audio hardware.
- Renamed EffectQueryNext() function to EffectQueryEffect() and changed operating mode:
now an index is passed for the queried effect instead of implicitly querying the next one.
- Added CPU load and memory usage indication in effects descriptor
- Added flags and commands to indicate changes in audio mode (ring tone, in call...) to effect engine
- Added flag to indicate hardware accelerated effect implementation.
- Renamed EffectFactoryApi.h to EffectsFactoryApi.h for consistency with EffectsFactory.c/h
Effect libraries:
- Reflected changes in Effect API
- Several fixes in reverb implementation
- Added build option TEST_EFFECT_LIBRARIES in makefile to prepare integration of actual effect library.
- Replaced pointer by integer identifier for library handle returned by effects factory
Audio effect framework:
- Added support for audio session -1 in preparation of output stage effects configuration.
- Reflected changes in Effect API
- Removed volume ramp up/down when effect is inserted/removed: this has to be taken care of by effect engines.
- Added some overflow verification on indexes used for deferred parameter updates via shared memory
- Added hardcoded CPU and memory limit check when creating a new effect instance
