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.

Maintain a per sensor circular buffer of last 10 sensor_events and the wall clock time

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.

Even when there isn't movement on the touchscreen we should produce
events for pressure and button state changes generated by external
stylii.

This completes the plumbing from ConsumerListener::onFrameReplaced into
SurfaceFlinger (and other consumers that may care).

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

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.

Sets a limit of 4k Layers which SurfaceFlinger will allow to be in
existence at any given time. An attempt to create Layers in excess of
this limit will fail with NO_MEMORY.

Adds a new method IGBP::allowAllocation, which controls whether
dequeueBuffer is permitted to allocate a new buffer. If allocation is
disallowed, dequeueBuffer will block or return an error as it
normally would (as controlled by *ControlledByApp).
If there are free buffers, but they are not of the correct dimensions,
format, or usage, they may be freed if a more suitable buffer is not
found first.

On normal Layers, we defer applying resize transactions until a buffer
of the correct size arrives. This breaks with sideband streams, because
buffers are not seen by SurfaceFlinger. This change applies
transactions immediately for Layers which have a sideband stream
attached to avoid that problem.

Temporarily increase the stylus timeout while we figure out where the

Sometimes stylus data will be delayed by 30 - 40ms. By increasing the
timeout we pretty much always pick up stylus data and the touch
latency feels surprisingly small.

This prevents us from dropping any states (namely the pressure
transition from non-zero to zero) if we get the touch up before we
get the stylus data.

This modifies EventThread such that its phase offsets for both
Choreographer and SurfaceFlinger may be modified at runtime. It also
plumbs this functionality up to the SurfaceFlinger debug interface so
that it is possible to rapidly test different offsets without
restarting the framework.
