- Remove unused GRALLOC_USAGE_PRIVATE_PMEM flag. This flag is no
longer used.
- Flush ashmem region cache instead of Invalidating it.

Whenever there is a change in the buffer geometry, set a flag in the
gralloc handle stating that the buffer geometry has changed.
In the HWC, whenever we encounter an update in the geometry, if the
channel is already open, we just call the necessary ioctls to update
the overlay information and not unnecessarily open/close channels.

The new perform api will update the width, height and
format of the buffer in the gralloc handle.
The GRALLOC_MODULE_PERFORM_DECIDE_PUSH_BUFFER_HANDLING perform
is not longer used in Honeycomb. Remove unused code.

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.

PRIV_FLAGS_NEEDS_FLUSH will trigger an ioctl call into the PMEM
driver in unlock(), so it makes not sense to set this flag for
non pmem buffers.

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.

make sure to reject incompatible buffers in special function
GRALLOC_MODULE_PERFORM_CREATE_HANDLE_FROM_BUFFER
we use ioctl(PMEM_GET_SIZE) to validate that the given buffer is indeed
a pmem buffer.
add a way to convert a mapped "pushbuffer" buffer to a gralloc handle
which then can be safely used by surfaceflinger
also make sure to not send empty rectangles to the MDP.
