this optimization didn't improve performance and in fact
seemed to hurt more than anything else. it also made
things a lot more complex as it introduced edges cases
when switching to/from h/w composer.

SurfaceTexture will modify the crop rect so it matches
the desired output aspect ratio when the scaling
mode is NATIVE_WINDOW_SCALING_MODE_CROP. Added a test
for this new scaling mode.

Add a new API native_window_set_buffers_user_dimensions to allow native
applications to override the native window size for the default buffer size.
This has lower precedence than the existing
native_window_set_buffers_dimensions and allows the two to co-exist.

surfaceflinger will now handle each surface post
as soon as possible and handle the composition
itself at VSYNC time as usual.

If the EGL implementation supports the EGL_IMG_hibernate_process
extension, use it to hibernate (and hopefully release memory or other
resources) when the process isn't actively using EGL or OpenGL ES. The
idleness heuristic used in this change is:
(a) Wake up when entering any EGL API call, and remain awake for the
duration of the call.
(b) Do not hibernate when any window surface exists; this means the
application is very likely in the foreground.
(c) Do not hibernate while any context is made current to a thread.
The app may be using a client API without the EGL layer knowing,
so it is not safe to hibernate.
(d) Only check these conditions and attempt to hibernate after a
window surface is destroyed or a thread's context is detached. By
not attempting to hibernate at the end of every EGL call, we avoid
some transient wakeups/hibernate cycles when the app is mostly idle,
or is starting to become active but hasn't created its window
surface yet.
On a Galaxy Nexus, hibernating frees 1567 VM pages from the process.
Both hibernating and waking can take anywhere from 30ms to over 100ms
-- measurements have been very inconsistent.

This is in preparation for a change that will hibernate the underlying
EGL when idle. Instead of a bare egl_display_t*, get_display() now
returns a egl_display_ptr, which acts like a smart pointer. The
"wakecount" counter managed by the smart pointer isn't used for
anything in this change. It will be used to make sure we don't
hibernate when any thread is in an EGL call, without having to hold a
mutex for the duration of the call.

BufferQueue is now more flexible as it can be used
by SurfaceMediaSource in addition to SurfaceTexture.

The umask changed for init. We have to force /data/anr to be world
readble and /data/anr/traces.txt to be world writable so dalvik
processes can write to it.
Hopefully this is a short term change while we investigate tightening
up these permissions.

This change adds a debug option to EGL to use an EGLSyncKHR each frame to
determine when the GPU finishes rendering the frame.

These keys are specific to Japanese hardware keyboard which can be
used by input method.
Patch ported from AOSP, with the addition of KANA.
