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)

Adds a getConsumerName method to IGraphicBufferProducer and Surface.
Currently, the name is cached inside of IGBP and is update on connect

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).

Reduces the number of resync samples that DispSync will attempt to
collect without an intervening present from 12 to 4. The former value
was causing excessive power draw for some vendors' implementations, and
reducing it doesn't seem to harm anything.

In cases where SurfaceFlinger is applying a color matrix (usually for
accessibility features), we previously would perform a render-to-
texture for the initial composition, and then apply the matrix during
a copy to the framebuffer. This changes that behavior to just apply the
matrix during composition without a render-to-texture pass.
This may result in a perceived change of the image in cases with alpha
blending, since the blending is performed at a different stage of the
pipeline and the system effectively performs non-linear blends.
However, neither this nor the prior render-to-texture pass is strictly
correct in that regard, and this approach is less error-prone and
likely faster.

Adds some more safety checking for cases where we get an error while
trying to create the EGLImage. The checking puts the Layer into a
failed state after detecting an error, since the shadow queue may no
longer be synchronized.

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 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.

Occasionally we'll receive the stylus up signal (pressure = 0) before
we receive the touch screen up signal. Rather than giving pointer a
pressure value of 0 (which is one of the signals of hovering) or
falling back to the touchscreen pressure values (which would make for
an inconsistent stream), use the previous pressure value which should
always be non-zero for a stream of fused data.

When a Layer's sideband stream is set, apply any pending transactions.
Otherwise they would never be applied since sideband streams don't

(cherry picked from commit 3b04e1383eca6cb1d43ebe23a421c427007690c7)
SurfaceFlinger's (Layer's) shadow copy of the BufferQueue queue was
getting out of sync for a few reasons. This change fixes these by
doing the following:
- Adds a check to re-synchronize the shadow copy every time we
successfully acquire a buffer by first dropping stale buffers before
removing the current buffer.
- Avoids trying to perform updates for buffers which have been rejected
(for incorrect dimensions) by SurfaceFlinger.
- Adds IGraphicBufferConsumer::setShadowQueueSize, which allows the
consumer to notify the BufferQueue that it is maintaining a shadow
copy of the queue and prevents it from dropping so many buffers
during acquireBuffer that it ends up returning a buffer for which the
consumer has not yet received an onFrameAvailable call.
