- Add a boolean to BufferItem to track whether single buffer mode is
  enabled. When it is, force SurfaceFlinger to acquire a new buffer
  and refresh on every vsync.

- Adds a single buffer mode to BufferQueue. In this mode designate the
  first dequeued buffer as the shared buffer. All calls to dequeue()
  and acquire() will then return the shared buffer, allowing the
  producer and consumer to share it.
- Modify the buffer slot state tracking. Add a new SHARED state for
  the shared buffer in single buffer mode. Also track how many times
  a buffer has been dequeued/queued/acquired as it's possible for a
  shared buffer to be both dequeued and acquired at the same time, or
  dequeued/acquired multiple times. This tracking is needed to know
  when to drop the buffer out of the SHARED state after single buffer
  mode has been disabled.
- Add plumbing for enabling/disabling single buffer mode from Surface.

Add API for fetching the next frame number to be produced by
a given buffer producer. Add an API to SurfaceComposer to 
defer execution of the current transaction until a given frame number. 
Together these may be used to synchronize app drawing and surface 
control updates.

On klp-dev, UINT16_MAX isn't available unless __STDINT_LIMITS
is defined, which it's not for this code. This isn't relevant
for later branches due to bionic commit
e2a292d278b94fec3d078b1f1b27c1f89942c276

Don't use UINT16_MAX when we can just hardcode 65535.

IBinder has a new common interface for sending shell commands
to it.  This can be implemented by system services to provide
a shell interface to the service, without needing to have separate
shell java code.

Also add a new "cmd" command line tool, which invokes the shell
command method on a system service.  This is much like dumpsys,
but for shell commands.

The Volantis driver will dequeue a buffer in eglCreateWindowSurface.

- Remove the requirement that no buffers be dequeued when calling
  setAsyncMode() on a BufferQueueProducer, since this gets called
  from eglSwapInterval.
- Modify the tests to call setMaxDequeuedBufferCount before calling
  eglCreateWindowSurface.

Towards deprecation of SharedBuffer

Change-Id: I9c853c86fb057280013405cb8c3c725e13175ea4

Currently keyboard maps allow to assign character sequences to key
events and allow specifying a so-called "fallback" key events that are
re-injected into input stream if target application indicates that it
was not able to handle the original key event. Unfortunately there is no
way to perform substitution before handing the event to applicationis.

This change adds a new keymap keyword "replace" that allows users query
"replacement" actions for key (if any), with the intent that such
replacement happens early in the event handling process.

  waitForFreeSlotThenRelock, and QueueBufferInput.
- Instead use the persistent flags mDequeueBufferCannotBlock and
  mAsyncMode to determine whether to use the async behavior.

As far as I can tell (e.g. https://goo.gl/nxpFBZ from 2009),
BnServiceManager is unused. It's only relevant for
libbinder-based C++ daemons implementing the
IServiceManager.aidl interface. service_manager.c rolls its
own binder code instead.

- Rename setDefaultMaxBufferCount() to setMaxBufferCount(). Modify it
  to be hard maximum on the number of buffers that can't be overwritten
  by the producer.
- Enforce the maximum buffer count in setMaxAcquiredBufferCount(),
  setMaxDequeuedBufferCount(), and setAsyncMode().
- Remove mOverrideMaxBufferCount as it's no longer needed since
  overriding is no longer possible.
- Expose setMaxAcquiredBufferCount() in GLConsumer.
- Remove disableAsyncBuffer(), it was only being used for single buffer
  mode. Single buffer mode is now achievable with setMaxBufferCount().
