This is used by framework to query buffer consumers (e.g. video encoders)
about required usage bits.

Incoming surface damage was not aware that the EGL implementation was
rotating buffers in response to SurfaceFlinger's transform hint. This
didn't affect all cases because the effect was to apply a 90 degree
rotation instead of a 270 degree rotation. For full-screen updates,
things more or less worked, but in other cases this caused corruption.
This fixes that by correctly undoing the effect of rotated buffers on
the incoming surface damage, and then passing that damage down
untouched to HWC.

Cherry-pick from master
This change adds four new stem keycodes for Android Wear. These
keycodes are intended to represent the various hardware buttons
around the watch. There is one primary stem key that will be used
for power/settings and three generic stem keys that will be
customizable.

This allows changes to the SECURE flag to propagate down to
Layers in SurfaceFlinger so that WindowManager can change it on the fly
in response to device policy updates.

Discover the logcat buffer size, divide by the worst storage
speed in kb/s, and multiply by ten to estimate the timeout in
ms for each named buffer. If that value is less than 20 seconds,
then select 20 seconds. Apply this to each logcat request.

Dumpsys utility accesses layer compositionType variable
with out proper protection. These variables are modified
during hwc_prepare call. Existing HAL lock protection is not
sufficient to address this issue. Failure to do this will
result in incorrect state reporting in dumpsys.
A new displayLock mutex in HWComposer will be used in both
dumpsys and draw calls to ensure correct state is accessed.

(cherry picked from commit e54506b81a)
Validate the display binder by adding a NULL check in getDisplayConfigs.
This will prevent a false match if the caller queries the display
configs for an inactive display (whose binder is NULL by default).
Without this change we might end up attempting to index the display
config array, which is unpopulated for inactive displays, and this will
result in a crash. (See getDisplayInfo in SurfaceComposerClient.cpp for
an example of this scenario)

(cherry picked from commit ac71c26e9180d9d181be5ec9e45da72d39144a8b)
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.

Given a pair of absolute paths {from_path, to_path} , check that
they are both valid apk subpaths (eg. /data/app/package/foo) and
link(2) to_path to from_path. This is required by staged installs,
where we link existing apks and oat files to their staging location.

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.
