The EGL 1.4 spec section 3.5.1 states that EGL_BAD_ALLOC should be set
if the supplied window already has an associated EGLSurface, not
EGL_BAD_NATIVE_WINDOW as is currently set.

The previous implementation assumed that the HWC could read and write
the same buffer on frames that involved both GLES and HWC composition.
It turns out some hardware can't do this. The new implementation
maintains a scratch buffer pool to use on these mixed frames, but on
GLES-only or HWC-only frames still does composition directly into the
output buffer.

Vsync array size is specified as HWC_DISPLAY_TYPES_SUPPORTED whose
value luckily happens to be 2. That enum is actually used for querying
hwc for the number of displays supported.
The implementation file EventThread.cpp correctly accesses the array
upto HWC_NUM_DISPLAY_TYPES

sensorservice would deadlock if for some reason
a sensor failed to enable.
simplifed the code a bit, and made it behave a little
closer to mr1.1 -- I couldn't convince myself that
some changes in how locks were used were correct.

When acquiring a buffer, SurfaceFlinger now computes the expected
presentation time and passes it to the BufferQueue acquireBuffer()
method. If it's not yet time to display the buffer, acquireBuffer()
returns PRESENT_LATER instead of a buffer.
The current implementation of the expected-present-time computation
uses approximations and guesswork.

When a buffer had a crop (meaning its content is scaled to the window size)
and a window crop was defined, the resulting crop couldn't be expressed
properly because h/w composer's API was limited to integers, since
this is fixed in h/w composer 1.3, we take adventage of this to
make sure we get the correct crop.
this bug could result in the buffer being scaled by an incorrect ratio and
be slightly offset; moreover, it would produce different results from the
GL code path, which is always correct.
