libstagefright: Squashed audio fixes from CodeAurora

libstagefright: Return seek position until seek has been processed

If it so happens that the client to TunnelPlayer (e.g. AwesomePlayer)
queries for the current time before data from the new seek position
is given to the compressed driver, we need to return the seek position

libstagefright: Use 64 bit offsets only when needed.

For enabling >2GB recording, 64 bit offsets are
needed for file writing. So, this feature was turned
on by default. This in turn increased the file size.
With this change, by default this feature will be
off and turned on only when required.

- Use 64 bit offsets for resolutions >= 720p.
- Limit maximum file size for recording to 4GB.
- Set max file size only if no value is set from the client.
- Fix MPEG4Extractor to use 64 bit offsets

libstagefright: TunnelPlayer sync fix

- Allow close on the AudioSink to be called from
  the extractor thread and the application thread.
- This fixes a race condition where an onPauseTimeout
  event scheduled from the main thread closes the
  audio sink while the extractor thread was about
  to issue write() on audio HAL. (note: on HAL, not audio sink)

Frameworks/av: Fix to prevent deadlock in AudioEffects

-Write is blocked waiting for effect chain lock and this causes
decoder thread to wait indefintely.
-Sometimes it is observed that effectschain is locked before
mLPAEffectChain is initialized and but unlocking is skipped if
mLPAEffectChain is initialized in between.Due to this LPA
silence and framework reboot issues are observed as
applyEffectsOn() cannot acquire lock to progress further.
-Use flag to check if all effects have been locked and unlock
accordingly to prevent the deadlock scenario.

framework/av: Fix for audio recording test through CTS

- Issue: Failure in stop is observed with the audio recording test
through CTS.
TestScenario: When the audio record test is initiated in the CTS
console, the recording session is force closed with a notification
File Size limit exceeded. Further, the stop fails with the same
message(notification of the File size exceeded error).

- Cause: The calculation of nTotalBytesEstimate for the recording
session exceeds the limit 95 percent of mMaxFileSizeLimitBytes.
As a result of size deficit, the recording is stopped at the
beginning of the recording session notifying
MEDIA_RECORDER_INFO_MAX_FILESIZE_REACHED.

- Fix: The factor size used in the calculation of nTotalBytesEstimate
has been updated properly for 64bit file offset setting. The
setParam64BitFileOffset in StagefrightRecorder::prepare() is executed
based on two additional validations so that the factor size is updated
appropriately.

audioflinger: apply volume on direct track when track is active

During back to back tunnel playback, we encounter a race condition
where setVolume can be called when the track is not updated to
active state. Fix to apply the volume on direct track only when the
track is in active state.

LPAPlayer: Update condition to ignore seek

- Reject seek if the new seek time is greater than the current
  position and within an empirical limit (default 60ms).
- This limit must be measured for each target.

audioflinger: for DirectAudioTrak, call startOutput before stream is active

For LPA and Tunnel playback, when resume is done in paused state, before
starting actual playback, volume should be set through AudioPolicy command
thread.
