This change adds a new HAL pixel format that indicates that the specific format
is to be chosen by the gralloc implementation.

This format describes buffers that are not structured like normal
image data, and can only be meaningfully understood by the endpoints.
As an example, this format is used for transporting JPEG-compressed
image buffers from the Camera HAL to the framework/apps.
Buffers of this format must have a height of 1 and a width equal to
their size in bytes. Otherwise their interpretation is up to the two
endpoints.

This change makes it clearer how to derive the stride of the Cr and Cb plane
from the stride of the Y plane for the YV12 pixel format.

This format is exposed outside of the HAL to applications.
RAW_SENSOR is a single-channel 16-bit format, typically representing raw
Bayer-pattern images from an image sensor, with minimal processing.
The exact pixel layout of the data in the buffer is sensor-dependent, and
needs to be queried from the camera device.
Generally, not all 16 bits are used; more common values are 10 or 12
bits. All parameters to interpret the raw data (black and white points,
color space, etc) must be queried from the camera device.
This format assumes
- an even width
- an even height
- a horizontal stride multiple of 16 pixels (32 bytes).

this is needed if a display/gpu driver needs to create
service threads that can block the main ui thread.
to avoid priority inversions, these must run at
HAL_PRIORITY_URGENT_DISPLAY

This patch moves camera- and graphics-related definitions out of the hardware
HAL layer and into system/core. These definitions are used both by the HAL and
by higher-level code as well. More functionality (e.g., audio definitions)
will be moved here as well.
