If there is a SKIP layer present, the SKIP layers are first composited
using the GPU. If there any layer below the SKIP layer that performs
any operations on the FrameBuffer, it results in undesireable results
on the screen e.g. artifacts, since SurfaceFlinger draws the SKIP layers
before the HWComposer.

A Google modification to eglCreateWindowSurface was
causing SurfaceFlinger to set its swap interval
value back to 1, regardless of the value set in the
debug.gr.swapinterval property.
This patch modifies the fb_setSwapInterval function
in gralloc to check the debug.gr.swapinterval
property and not change the swap interval if a value
is set there.

Do not choose GL_EXTERNAL_TEXTURE_OES for all formats, instead,
select between GL_EXTERNAL_TEXTURE_OES, and GL_TEXTURE_2D based
on the pixel format.
This change is done to reduce composition times.

This is a helper function that will return false if the given format is
supported by adreno drivers but not supported in GPU HW. For these
formats, adreno will use software color conversion routines to convert
them to acceptable format by the GPU HW. This may be required if we
want to avoid creating texture for certain formats when not absolutely
necessary. Could be defaulted to return true depending on a compile
time flag.

Display/libhwcomposer:Add intermediate stretch for low resolution clips
Copybit module has a limited stretch to scale a clip.
Hence we need to do a intermediate stretch before going

The x and y coordinates are derived properly from clip and dest rect with this fix.
- Even if rotation is involved, we need to start reading from the same point.
- Do scaling operation on the delta, and then add the source left and top values.
- If we scale the result of addition, we will not be reading source correctly.

Refactoring is necessary to attain flexibility in setting mdp overlay params
at runtime, while using composition bypass.
This change includes new APIs for setting crop rectangle, display params and
commiting mdp params, namely setCrop(), setDisplayParams() and commit(),
respectively.

When performing the setup for bypass operations, check the number
of bypass channels that are in open state. If the count does not
match the number of bypass layers, close all the bypass channels.
This is done to prevent the overlay channels from going into an
inconsistent/undefined state.

If module composition type is MDP or C2D and we have a skipped layer
(usually layers without backing buffers, layers with "invalid"
orientations or debug layers), mark every HWC layer below this layer
for GPU composition.
This logic is needed because ICS SF composes a bunch of z-ordered
HWC_FRAMEBUFFER (GPU) layers first and then the remaining bunch of
z-ordered HWC_OVERLAY layers last which breaks the overall z-ordered
layer rendering requirement. This logic also holds valid for 2-layer
bypass in ICS.

Validate the previous overlay and bypass handles before unlocking
the buffers. The reason for doing this, is that in certain use cases,
after the previous handles are stored, the buffer gets destroyed and the
handle is now invalid. The HWC however doesn't know that the handle is
invalid and tries to unlock the handle, resulting in a failure.
