When we have excess pixels that need to be removed from (for example)
the left and right sides, we currently do something like:
left += excess / 2;
right -= excess / 2;
If excess is odd, however, this removes 1 too few pixels since the odd
pixel gets rounded down twice. This changes the math to effectively:
left += excess / 2;
right -= (excess - excess / 2);
Which removes the correct total number of pixels.

Make sure that we don't go haywire if an exponential buffer growth
operation winds up wrapping integer range. Along the way, fix a
bookkeeping bug in BufferedTextOutput that would cause it to keep
spuriously realloc()ing on every append().

We now check for fd-legality before committing binder objects to
the flattened data buffer rather than after. Previously we would
wind up corrupting the parcel and incurring driver-level errors,
as well as potentially leaking FDs.

Adds a getConsumerName method to IGraphicBufferProducer and Surface.
Currently, the name is cached inside of IGBP and is update on connect
and dequeueBuffer, which should be good enough for most uses.

Add functions to allow a client to take over the ashmem region
that was transferred so that it can claim it for its own and
reuse it.
Add support for mutable ashmem regions too.

Attempts to replicate Java parceling in native code is fraught with

(cherry picked from commit f47a381001)
This change allows producers to set a generation number on a
BufferQueue. This number will be embedded in any new GraphicBuffers
created in that BufferQueue, and attempts to attach buffers which have
a different generation number will fail.
It also plumbs the setGenerationNumber method through Surface, with the
additional effect that any buffers attached to the Surface after
setting a new generation number will automatically be updated with the
new number (as opposed to failing, as would happen on through IGBP).

On devices that have the crop image extension the crop is not applied to the
transform matrix so we have to expect different results in this case.

Applies GRALLOC_USAGE_ALLOC_MASK to the incoming usage bits before
calling alloc on the gralloc module. This filters out the new flag
GRALLOC_USAGE_FOREIGN_BUFFERS, which is used to send a hint to the
producer, but which does not affect the allocation of buffers.

Introduce ACTION_BUTTON_PRESS and ACTION_BUTTON_RELEASE as actions to
signal a button press or release. If these actions happen
simulanteously with a DOWN or UP event then they're explicitly
ordered to happen after the DOWN or preceding the UP in order to send
them to the most recently targeted view.
Also, introduce new stylus button constants that differ from the
constants we use for mouse buttons.

This change places BufferQueue into a predictable state where
allocation is allowed whenever a producer connects. This allows clients
to disconnect and reconnect without having to worry about being locked
out of allocation.

This changes the way that SurfaceFlinger's shadow buffer management
works such that instead of tracking the size of the shadow queue in the
BufferQueue, SF tracks the last frame number it has seen, and passes
that into the acquireBuffer call. BufferQueueConsumer then ensures that
it never returns a buffer newer than that frame number, even if that
means that it must return PRESENT_LATER for an otherwise valid buffer.
