8dddc99010 libgui: Change BufferQueue to use free lists
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.

3be1c6b60a libgui: Enable -Weverything and -Werror
Enables -Weverything and -Werror, with just a few exceptions for
warnings we can't (or shouldn't need to) work around.

Cherry pick of I034abec27bf4020d84af60d7acc1939c59986dd6 plus a
couple of minor changes to CpuConsumer.cpp to make it work with a
prior change:
    Uncomment CC_LOGV on line 46
    Change C-style cast to static_cast on line 71

7d83187103 Make string literal concatenation play nice with C++11.
In C++11 mode, "foo"MACRO_THAT_EXPANDS_TO_STRING gets lexed as a user
defined literal. Add space around the macro.

Had missed these when resolving merge conflicts last night.

78014f32da BufferQueue: release mutex while allocating. DO NOT MERGE
BufferQueueProducer::allocateBuffers used to keep the BufferQueueCore
mutex while doing the buffer allocation, which would cause the consumer
(which also needs the mutex) to block if the allocation takes a long
time.
Instead, release the mutex while doing the allocation, and grab it again
before filling the slots. Keep a bool state and a condvar to prevent
other producers from trying to allocate the slots while the mutex is
released.

f0eaf25e92 BufferQueue: Add producer buffer-released callback
Add a callback to the producer side, onBufferReleased, which will be
called every time the consumer releases a buffer back to the
BufferQueue. This will enable a buffer stream splitter to work
autonomously without having to block on dequeueBuffer.

The binder object used for the callback replaces the generic IBinder
token that was passed into IGraphicBufferProducer::connect to detect
the death of the producer. If a producer does not wish to listen for
buffer release events, it can pass in an instance of the
DummyProducerListener class defined in IProducerListener.h, if it even
cares about death events (BufferQueue doesn't enforce the token being
non-NULL, though perhaps we should).

399184a4cd Add sideband streams to BufferQueue and related classes
Sideband streams are essentially a device-specific buffer queue that
bypasses the BufferQueue system. They can be used for situations with
hard real-time requirements like high-quality TV and video playback
with A/V sync. A handle to the stream is provided by the source HAL,
and attached to a BufferQueue. The sink HAL can read buffers via the
stream handle rather than acquiring individual buffers from the
BufferQueue.

3e96f1982f Change BufferQueue into producer/consumer wrapper
Now that BufferQueue has been split into core + producer + consumer,
rewrite BufferQueue to be a thin layer over a producer and consumer
interface. Eventually, this layer will be deprecated in favor of
only using either the producer or consumer interface, as applicable.
