Add support for the userspace to make MDP
avoid flushing the source image buffer
This change is needed if we are using
cached video buffers. Since the MDP driver
used to flush the entire source buffer before
the blit, it was a huge overhead in terms of CPU
usage for cases where the entire buffer didn't
really need flushing. Any clients that modify
the video buffers with CPU should now ensure that
they flush the region that they modified (if the
memory is cached)

Add an api to copy bypass buffer. De-couple
comp. bypass functions from HDMI feature defines.

Revert "libgralloc-qsd8k: Set the framebuffer offsets correctly"
This reverts commit 09a31858f42978c29e0c7014713748d413b3c587.
It is no longer a requirement for GPU to be 4k aligned, hence
reverting these 2 changes.

Design now uses OverlayUI class. Flow goes through gralloc
to avoid race conditions with mirroring, when video is
played via Gallery.

allocated from.

The offsets for the framebuffer needs to start at a 4K aligned address.
Calculate the additional delta for the yoffset, the virtual address for flipping
as well as the total framebuffer size required to achieve this

- The ioctl call from getOrientation is removed.
- In gralloc use getOrientation instead of storing the
orientation.

Add the state machine for overlay configuration. When connected,
check whether the TV on HDMI is 3D capable or not using the EDID
info. Show L channel on primary panel; and R channel on 2D TV if
non 3DTV is connected via HDMI, else switch TV to 3D mode.

Add support for Side-by-Side full, Side-By-Side-half formats in the overlay.
The Side by Side half formats could either be in Left-Right or Right-Left mode.

The 3D input and out formats are passed along with the regular color format.

libgralloc-qsd8k: Add support for non-aligned width on HDMI
While creating overlay channel for HDMI consider the aligned
width and set the crop rectangle to the actual width and height.

The purpose of this change is to add support for allocating gralloc buffers
from either /dev/pmem or /dev/pmem_adsp depending on the usage flags. It does
this by factoring out and abstracting the interactions with the pmem device.
For /dev/pmem allocations, the kernel allocator is not used, so a single master
fd is opened, and all the allocations are sub-allocated from that by gralloc.
For /dev/pmem_adsp the kernel allocator is used, so it simply opens a new fd
for each allocation.
A very basic unit test that can be run on the host is included. It requires
gtest, so to run it on a host system gtest must (currently) be compiled with
BUILD_WITH_ASTL=true.

The GPU now correctly maps everything throug hthe MMU so physical addresses
are no longer needed.
