Support triple application buffers

This change modifies surfaceflinger to use 3 application buffers
by default for performance improvement.

Select texture target based on pixel format

Adreno is not optimized for GL_TEXTURE_EXTERNAL_OES, making GPU
utilization (and power), high with GL_TEXTURE_EXTERNAL_OES for
RGB formats.

Change texture target from GL_EXTERNAL_TEXTURE_OES to dynamically
select between GL_EXTERNAL_TEXTURE_OES, and GL_TEXTURE_2D based
on the pixel format.

This change is done to reduce the composition time for 8x55

Surfaceflinger: Modify setFormat() API to set 3D format.

setFormat() API is modified to accept 3D formats from applications.
This change is required for 3D game usecase so each layer can be
marked as 3D and can be sent to overlay for rendering.

SurfaceTexture: Initialize S3D format member variable to 0

Without initialization mS3DFormat may hold garbage value, and
may corrupt the format calculations in libQcomUI.

This change is done to fix UI corruption.

Surfaceflinger: Compose UI in S3D format

The new member of LayerBase takes care of identifying layer for 3d
composition. When 3D composition is required the Layer takes care
of drawing in 3D format

SurfaceFlinger: Return error on invalid buffer creation

When a buffer is re-allocated on reconfiguration, return NULL
if there is an error in re-allocation.

Also, remove warnings during compilation.

SurfaceFlinger: Skip composition when rotation is not completed

When rotating, each layer's buffer is already changed to
new orientation before SurfaceFlinger gets the signal from
Window Manager. If the orientations of all the buffers are
changed to new orientation, then that's fine. But, sometimes,
only one buffer is changed and others remain the same.
In this case, skip composition.

SurfaceFlinger: Prevent screencap command from failure

For secure windows, screen capture fails, and the screencap command
falls back to reading from the framebuffer directly.

Instead, draw a black screen on the framebuffer object if there is a
secure session, so that secure layers cannot be captured.

SurfaceFlinger: notify HWC when layer is in asynchronous mode

When the layer is in asynchronous mode the HWC may choose a
different composition method.

Remove 'Bypass Texture Creation' hack in frameworks

Graphics driver (ADRENO) was updated to convert the texture on
first use. Hence this change is no longer required.

libRS: Correct the screen freezing issue

This fixes a timing issue where it could calculate a delay of 0
(indicating wait forever) when it has no pending commands to actually
execute. In such cases, it should just break out of the playback loop.
This also fixes a small issue with returning whether or not to redraw.

SurfaceTextureClient: Add support for external only usage flags.

Add support for GRALLOC_USAGE_EXTERNAL_ONLY and
GRALLOC_USAGE_EXTERNAL_BLOCK to be set as a part of usage flags.
These flags if present will be cached by SurfaceTextureClient.
Incoming usage flags will be ORed with these, if present.
