ANDROID_swap_rectangle allows to specify the rectangle affected by eglSwapBuffers(), anything outside of this rectangle is unchanged. in particular EGL_BUFFER_DESTROYED only applies to that rectangle. This extension as well as EGL_BUFFER_PRESERVED allow major optimizations on surfaceflinger, which can redraw only the dirty area during compositing.
However, ANDROID_swap_rectangle allows further optimizations in EGL by reducing the amount of copy-back needed. ANDROID_swap_rectangle is particularily important for software implementations.
This is the first step in a multi-step change to move from the old
specific callbacks to a generic callback. This will allow future
flexibility in the interface without requiring binder rewrites.

* commit '4488b11c51ad8f5b8330279a9405e5a0f8586aa4':
Add some C++ code to do raw files for backup
- Currently the lock/unlock path is naive and is done for each drawing operation (glDrawElements and glDrawArrays). this should be improved eventually.
- factor all the lock/unlock code in SurfaceBuffer.
- fixed "showupdate" so it works even when we don't have preserving eglSwapBuffers().
- improved the situation with the dirty-region and fixed a problem that caused GL apps to not update.
- make use of LightRefBase() where needed, instead of duplicating its implementation
- add LightRefBase::getStrongCount()
- renamed EGLNativeWindowSurface.cpp to FramebufferNativeWindow.cpp
- disabled copybits test, since it clashes with the new gralloc api
- Camera/Video will be fixed later when we rework the overlay apis

Bug fix(1807910): media recorder crash due to the use of locked camera object (last part)
Merge commit '0a9b5bbb47a965238ca0e1e699d61d7ddd054742'

Fix a media server crash (bug 1807910): part one
First, the window manager tells us when a surface is no longer needed. At this point, several things happen:
- the surface is removed from the active/visible list
- it is added to a purgatory list, where it waits for all clients to release their reference
- it destroys all data/state that can be spared
Later, when all clients are done, the remains of the Surface are disposed off: it is removed from the purgatory and destroyed.
In particular its gralloc buffers are destroyed at that point (when we're sure nobody is using them anymore).
Surfaces are now destroyed once all references from the clients are gone, but they go through a partial destruction as soon as the window manager requests it.
This last part is still buggy. see comments in SurfaceFlinger::destroySurface()
Add a factory method that creates a Camera object from a remote client
Next:
The changes in authordriver.cpp and android_camera_input.cpp will come.
and the constructor for Camera object will be removed.

Fix runtime resource selection logic.
Fix isBetterThan so that o or this may be supperior at any stage.
Used to only handle this-better or tie at each stage, biasing against o.
Also allows reset of unit test to succeed. Fixes bug 1709202.
AudioTrack, AudioRecord:
- remove useless mAudioFlinger member of AudioTrack and AudioRecord.
- signal cblk.cv condition in stop() method to speed up stop completion.
- extend wait condition timeout in obtainBuffer() when waitCount is -1 to avoid waking up callback thread unnecessarily
AudioFlinger:
- remove some warnings in AudioFlinger.cpp.
- remove function AudioFlinger::MixerThread::removetrack_l() as its content is never executed.
- remove useless call to setMasterVolume in AudioFlinger::handleForcedSpeakerRoute().
- Offset VOICE_CALL stream volume to reflect actual volume that is never 0 in hardware (this fix has been made in the open source): 0.01 + v * 0.99.
AudioSystem.java:
- correct typo in comment
IAudioflinger, IAudioFlingerClient:
- make AudioFlinger binder interfaces used for callbacks ONEWAY.
AudioHardwareInterface:
- correct routeStrings[] table in AudioHardwareInteface.cpp
The WindowManager side of Surface.java holds a SurfaceControl, while the client-side holds a Surface. When the client is in the system process, Surface.java holds both (which is a problem we'll try to fix later).
SurfaceControl is used for controling the geometry of the surface (for the WM), while Surface is used to access the buffers (for SF's clients).
SurfaceFlingerClient now uses the SurfaceID instead of Surface*.
Currently Surface still has the SurfaceControl API and is implemented by calling into SurfaceControl.
To deal with Java's lack of destructors and delayed garbage collection, we used to duplicate Surface.cpp objects in some case; this caused some issues because Surface is supposed to be reference-counted and unique.
