595264f1af BufferQueue improvements and APIs changes
this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:

- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
  those flags are used to put the BufferQueue in a mode where it
  will never block if both flags are set. This is achieved by:
  - returning an error from dequeueBuffer() if it would block
  - making sure a buffer is always available by replacing
    the previous buffer with the new one in queueBuffer()
    (note: this is similar to what asynchrnous mode used to be)

Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.

1585c4d9fb Pay attention to buffer timestamps
When acquiring a buffer, SurfaceFlinger now computes the expected
presentation time and passes it to the BufferQueue acquireBuffer()
method.  If it's not yet time to display the buffer, acquireBuffer()
returns PRESENT_LATER instead of a buffer.

The current implementation of the expected-present-time computation
uses approximations and guesswork.

c5d7b7d323 BufferQueue: track buffer-queue by instance vs. by reference
Instead of representing the buffer-queue as a vector of buffer
indices, represent them as a vector of BufferItems (copies).
This allows modifying the buffer slots independent of the queued
buffers.

As part of this change, BufferSlot properties that are only
been relevant in the buffer-queue have been removed.

Also, invalid scalingMode in queueBuffer now returns an error.

ConsumerBase has also changed to allow reuse of the same
buffer slots by different buffers.

e692ab9a6b fix uninitialized variables in GLConsumer
mDefaultWidth, mDefaultHeight and mCurrentScallingMode are now
initialized to the same default value that BufferQueue uses.

ca08833d5e don't use compile-time configuration of libgui as much as possible
We now detect at runtime which sync features to use, which
allows us to remove a lot of the compile-time configuration
options. There  is still one option though, to disable
KHR_fence_sync on some devices (which are more efficient
without it).

- added a backdoor to get the vendor's EGL strings

the new logic is:
- use always ANDROID_native_fence_sync if available
- fallback to KHR_fence_sync if available and not disabled
  by the compile-time option
- use KHR_wait_sync if available and either of the above is
  enabled

2adaf04fab Rename ISurfaceTexture and SurfaceTexture
The C++ class names don't match what the classes do, so rename
ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.
