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.

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 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.

Clears the frame number of a slot when it is freed, since it is used
to determine if a released buffer is stale.

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.

Surface::{cancel,queue}Buffer and GraphicBufferMapper::lockAsyncYCbCr take the

Adds a NATIVE_WINDOW_BUFFER_AGE query, which returns the age of the
contents of the most recently dequeued buffer as the number of frames
that have elapsed since it was last queued.

works correctly.

Change-Id: I3979ea6121aaf14845f0554477b778770413581e
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.

BufferQueue used to choose free buffers by scanning through its array
of slots and picking one based on timestamp. This changes that
mechanism to use a pair of free lists: one with buffers attached and
one without. This makes it easier to choose either type of free slot
depending on the needs of the current operation.
Fixes an issue with the first version of this change, found in bugs
20482952, 20443314, and 20464549.

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.
