If available, surfaceflinger will use the hwc setCursorPositionAsync()
api to change the position of supported cursor layers outside of
the usual prepare/set loop.

Commit 78014f32da introduced a bug that
made us pre-allocate buffers into the last available free slots instead
of the first available ones. This in turn caused more re-allocations,
and possibly triggered driver bugs.

i) Send ack for wake_up sensors on the socket connection instead of using Binder RPC.
ii) Cache events per connection in case there are write failures. Compute cache size
from FIFO counts of sensors.
iii) Send FlushCompleteEvent only for apps that explicitly called flush().

Change the mExtras field in Binder.h to be a stdatomic.h atomic
value, and replace references to it with proper stdatomic.h calls.
This removes one of a small number of remaining 64 bit
android_atomic references. It also replaces the erroneously
non-atomic read accesses to mExtras.
It would be better if this used the C++11 <atomic> facility,
but we don't quite have that yet.

If getNativeBuffer() is called on a NULL GraphicBuffer the
static_cast of this from GraphicBuffer* to ANativeWindowBuffer*
will return a small pointer like (ANativeWindowBuffer*)0x10.
This value can propagate past NULL checks until it causes a crash
far away from the original NULL pointer. Crash immediately
instead.

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.

(cherry picked from commit ea96044470)
In most cases, EGLImages can be created one-to-one with graphic
buffers in slots, but that was difficult due to some special
cases:
- ReleaseTexImage binds a custom 'unslotted' debug image.
- When all slots are freed, we still need to hang on to one.
These cases were handled by keeping an additional reference to
the 'current' buffer (mCurrentTextureBuf), but we would create
new images since we can't reference count them in the same way.
This patch uses the same semantics, except that it reference
counts the image (an EglImage wrapper class) rather than just
buffer. The wrapper class also detects the cases when we need
a new EGLImage, and only creates them in those rare cases.
