libstagefright: Set initial buffer size for H264 codec

For Google h264 decoder, the input port buffer size is
set to 8192 bytes, and for usecases where data source
does not specify input buffer size, there is a crash on
assert when the buffer size is larger than 8192 bytes.

Added change to set input buffer size for H264 to 80k.

stagefright: OMXCodec: free allocated port-buffers if init fails

If an error is encountered while allocating port buffers, init
would fail and buffers already allocated would not be freed.
Move OMXCodec to ERROR state and explicitly stop omx component,
hence forcing free-ing up of allocated buffers.
Also defer setting port-status to ENABLED only after having
moved the component to IDLE and add graphicBuffer to port-
buffers-list only if setBuffer is successful.

NuPlayer: Fix parsing RTSP play response from special server

- In some non-standard server, a different play response will be returned,
  which will cause CHECK failure
- Change in parsePlayResponse(), to get the current track index

stagefright: Omit audio from timelapse recording use-case

Timelapse recording is only valid for video encoding, but audio
is subjected to the same infinite wait. This can result in an ANR
if encoded data is not being produced. Only wait forever in video
use cases.

audioflinger: Fix cleanup of asynccallback thread

AsyncCallbackThread will not be spawned if the output
profile does not support non-blocking output or if the HAL does not
support set_callback API.

Add a check for validity of callback thread object before deleting it.

  seeking.

stagefright: Fix AV sync issue for cached audio sources

Non-HTTP sources may continue to fetch audio data after video has
already seen a seek request causing audio to run ahead. When video
sees a seek request, audio should pause, resuming once it too has
handled the seek request.

audioflinger: Handle pause /resume in stopping state

-Pre-requisite:
 Perform seek on the clip. After seek the data remaining till EOS
 is little more than the driver and common block buffering.
-Framework state:
 Offload thread is waiting for signal from the HAL for a free
 buffer. Audio Player calls sink stop on reaching EOS. Audio
 track is waiting on obtain buffer for a free space in common
 block to send the last buffer. The track is moved to stopping
 state as input EOS is reached.
-Issue:
 Perform pause/ resume in this state(STOPPING), Audio playback
 does not resume.
-Fix
 Ensure resume is called in stopping state if frames ready is
 greater than zero.

AudioFlinger: Modify flush handling for offload path

Do not allow an offload track to directly control the offload thread
behavior. OffloadThread can check for any pending flush reporting
by its active tracks and decide to flush the HW or not.

libstagefright: Handle offload fallback for WAV content

audioflinger: remove unecessary call to HAL

On a flush, OffloadThread resets its state about HAL being paused.
For the sake of consistency, it is now expected that after a flush
as HW is no longer paused, the resume call is unnecessary.
