hardware/libhardware/include was being included with -isystem, which
hides warnings. The gralloc enum values are used as bitmasks on
unsigned types, explicitly mark them values as unsigned in order to
force the type of the resulting enum to be unsigned.

map_usage_to_memtrack takes in the gralloc usage flag and returns a
const char pointer containing the memtrack tag.
This function should be used to find the appropriate memtrack tag that
needs to be used after allocating buffers. This will help in-kernel
memtrack module to classify memory into pre-defined buckets.

Adds GRALLOC_USAGE_FOREIGN_BUFFERS, which a consumer may set as a usage
flag if it intends to attach buffers that it has not detached from the
BufferQueue. It provides a hint to the producer (who may query the
consumer usage bits) that it may receive a buffer from another
BufferQueue, so that it can exit during initialization, hopefully with a
meaningful error message, if such buffers are not supported.
Also adds GRALLOC_USAGE_ALLOC_MASK, which is applied to usage bits
before calling alloc on the gralloc module, and prevents the module from
seeing GRALLOC_USAGE_FOREIGN_BUFFERS, since that usage flag is of no use
while allocating buffers.

On many devices, hardware cursors have stricter layout constraints than
other overlays. GRALLOC_USAGE_CURSOR indicates a buffer may be used as
a cursor; byte order and padding should be chosen accordingly.
GRALLOC_USAGE_CURSOR must not cause allocation failure. If the requested
properties (dimensions, format, other usage flags, etc.) aren't compatible with
the device's cursor hardware, the implementation must allocate the buffer
anyway, acting as if GRALLOC_USAGE_CURSOR were not specified.

The existing API exposed to clients for software lock/unlock forces the gralloc
implementation to complete these operations synchronously. This change adds new
entry points for lock/unlock functionality that is suited for use with Android's
explicit synchronisation concept. This provides scope for the gralloc module
to internally optimise the work it must do for lock/unlock and to hide this cost
from the client.

Align camera2's management of platform-opaque formats with rest of
framework. Instead of using CAMERA2_PIXEL_FORMAT_OPAQUE, use
HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED as the format for both the
camera HAL and for gralloc, and depend on the gralloc usage flags to
let the gralloc module select the appropriate real format for specific
stream endpoints.
Add a new gralloc usage for ZSL mode, where the camera service will
hold a streaming circular buffer of opaque full-resolution images
during camera preview. Since this is an opaque format that needs to be
optimized for 30fps operation, need gralloc to be aware of this use
case.

GRALLOC_USAGE_HW_CAMERA_WRITE is for camera outputs in the new camera HAL.
GRALLOC_USAGE_HW_CAMERA_READ is for sending previously captured camera
data back into the camera pipeline for further processing. For
example, for converting a raw sensor image into YUV or JPEG data.

fb and gralloc are part of the same HAL for now,

a new method, compostionComplete() is added to the framebuffer hal, it is used by surfaceflinger to signal the driver that the composition is complete, BEFORE it releases its client. This gives a chance to the driver to perfrom the proper synchronization.
- make sure to return an error if a buffer is locked twice or unlocked while not locked.
- added registerBuffer() and unregisterBuffer() to the gralloc module so that we can do some cleanup when a buffer is no longer needed. this became necessary after we removed map/unmap so we have a place to unmap buffers without the need of a kernel module.
- change the constants for GRALLOC_USAGE_SW_{READ|WRITE}_NEVER to 0, so that NOT specifying them means "NEVER".
