libstagefright: handle error when B-frame is sent to MPEG4Writer

Without this patch, writing B-frame to MediaMuxer will be blocked and
cannot return a result. This may cause an endless progress bar shown in
gallery when triming or muting some videos.

audio: Fix for failure in CTS MediaRecorderTest cases

 -Issue: MediaRecorder CTS test cases are failing.

 -Running the CTS test "testRecorderRandomAction" at
  beginning sets the huge file size and StageFrightRecorder
  set the 64 bit file offset. In MPEG4 writer
  estimateMoovBoxSize depends on a static const variable
  which uses this file offset info. As the variable to
  calculate estimateMoovBoxSize is static const it remains
  same for next media recording session even if file size
  is small.

 -Fix: Don't use static const variable which is used to
  calculate estimateMoovBoxSize as its value may change
  depending on file offsets.

RTSP: Fix crash issue while repeated pause/resume

While doing repeated pause-resume operation in RTSP streaming,
some times, the accessunit timeout check is being posted when
the streaming paused, and even after receving the EOS.
Due to this check, after the EOS, the number of packets received
will be zero and the session gets Teardown while the
streaming is paused. Upon resume, it leads to check failure and crash.

Changes are done such that the accessunit timeout check will
not be done in pause/seek state.
