a7e380396e Add support for direct EGLImageKHR use with pushbuffer API
We now always first try to use the EGLImageKHR directly before
making a copy with copybit. The copy may be needed when
EGLImage doesn't support the requested format, which is
currently the case with YUV.

ecc99c003b part of fix for [2363362] [Sapphire] Corrupted raw picture displayed during snapshot
make sure to fallback properly to software when copybit operation fails.
with this change, the preview image will at least be displayed in b&w
(since GL doesn't support the yuv format). This would also fix
2363506, but that one is now handled more cleanly.

c5e181f8b3 fix [2315900] Monochrome camera preview screen after launching camera
this was introduced by a recent change. when we try to figure out the size of
the yuv->rgb temporary buffer, the output resolution has not been computed yet
and an invalid buffer size is used. most of the time the allocation fails
and the system reverts to "standard" GL will uses onle the Y plane.

the allocation of the temporary buffer is moved to onDraw(), the first
time it is called, by that time, the window is positioned properly.

bbc21b01cf fix [2143798] Need to figure out how to do video on Passion w/ GPU
This builds on the EGLImage solution. We simply use copybit to convert from the
YUV frame into an EGLImage created for that purpose and proceed with the
regular EGLImage code.
We need to do this because "regular" GL doesn't support YUV textures.

We could improve upon this by detecting exacly what the GL supports and bypass
this extra step if not required, but we'll do this later if needed.

863e5fdde8 fix[2222341] Soft reset while going back from camcorder settings
add a way to convert a mapped "pushbuffer" buffer to a gralloc handle
which then can be safely used by surfaceflinger, without including
gralloc_priv.h

54ba51dff2 fix [2143798] Need to figure out how to do video
Use EGLImageKHR instead of copybit directly.
    We now have the basis to use streaming YUV textures (well, in fact
    we already are). When/if we use the GPU instead of the MDP we'll
    need to make sure it supports the appropriate YUV format.

    Also make sure we compile if EGL_ANDROID_image_native_buffer is not supported

3330b20303 fix [2167050] glTexImage2D code path buggy in SurfaceFlinger
When EGLImage extension is not available, SurfaceFlinger will fallback to using
glTexImage2D and glTexSubImage2D instead, which requires 50% more memory and an
extra copy. However this code path has never been exercised and had some bugs
which this patch fix.

Mainly the scale factor wasn't computed right when falling back on glDrawElements.
We also fallback to this mode of operation if a buffer doesn't have the adequate
usage bits for EGLImage usage.

This changes only code that is currently not executed. Some refactoring was needed to
keep the change clean. This doesn't change anything functionaly.

454ea68139 fix [2037525] Fail to start camera after adb sync new Camera
we ended-up locking a Mutex that had been destroyed.
This happened because we gave an sp<Source> to the outside world,
and were called after LayerBuffer had been destroyed.

Instead we now give a wp<LayerBuffer> to the outside and have it
do the destruction.

cbb288bfe8 fix [2068105] implement queueBuffer/lockBuffer/dequeueBuffer properly
Rewrote SurfaceFlinger's buffer management from the ground-up.
The design now support an arbitrary number of buffers per surface, however the current implementation is limited to four. Currently only 2 buffers are used in practice.

The main new feature is to be able to dequeue all buffers at once (very important when there are only two). 

A client can dequeue all buffers until there are none available, it can lock all buffers except the last one that is used for composition. The client will block then, until a new buffer is enqueued.

The current implementation requires that buffers are locked in the same order they are dequeued and enqueued in the same order they are locked. Only one buffer can be locked at a time.

eg. Allowed sequence:   DQ, DQ, LOCK, Q, LOCK, Q
eg. Forbidden sequence: DQ, DQ, LOCK, LOCK, Q, Q

1000170033 Add a flag to set whether the overlay has been initialized. Commit needs to be called at least once on each overlay, and it appears that sometimes this
doesn't happen because the visibility never changes.  With this change
the overlay parameter and position will be committed when either the visibility
of the window changes, or on the first call to visibility resolved, if it
hasn't already been done.

9a11206fe7 more Surface lifetime management
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()
