audio: do not invalidate stream used by voip

During the process of invalidation of voip streams,
actual driver is not closed so when it tries to open again
getoutput fails as only one instance of voip can be created.
so do not invalidate the tracks used by voip driver.

audio: Fix for OMXCodec::read() getting blocked

- Sometimes notification sound is not heard if it is played
  and stopped multiple times in a short duration.
- If OMXCodec::read() gets blocked for filled buffers while
  in pause, it never returns as mFilledBuffers is always empty.
  Due to this AudioTrack destructor never exits as it waits for
  the AudioCallback thread to unblock it.
- Ensure OMXCodec::read() returns even if timeout occurs while
  in pause and handle the same in AudioPlayer by returning zero
  bytes in AudioCallback.

 audio: Fix framecount calculation in AudioFlinger

 -Sharedblock implementation expects the framecount to
  be round up to the next highest power of 2. This is
  not done in TrackBase for non-voip case which leads
  to shared block getting corrupted.
 -Fix is to round up the framecount in TrackBase for
  all the audio formats.

libmedia: Increase offload shared buffer size

Ensure that AudioTrack and OffloadThread share at least twice fragment
size worth of buffer space. This helps avoid failure to restart
on an underrun

Camera: Rotate display if app doesn't use setDisplayOrientation.

Third party application not following setDisplayOrientation
logic properly and as a result preview used to come inverted.

Fix made to track setDisplayOrientation call invocation and
if no call had been made then, rotate the buffers accordingly.
