libstagefright: Check for data partitioned clips

- Check for DP clips in ESDS atom of mpeg4 clips
- If the clip is detected to have data partition, return a
  error, so that video decode will fallback to SW decoder

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.

stagefright: Cancel audioCheck event when setting nativewindow

In html5 playback, setNativeWindow_l() will be called twice
when switching from landscape to portrait mode. If the 2nd
setNativeWindow_l gets the LOCK before proceeding mCheckAudioStatusEvent
posted in the 1st setNativeWindow_l, it will get the infomation
that seeking is completed and won't do seeking in this run.

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.

stagefright: Handle acquireWakeLock failure case

When the power service is not running, acquireWakeLock fails, but
TimedEventQueue still keeps a reference count to a non-existent
wakelock. This causes an assertion failure when trying to free the
wakelock. Only increment the reference count and save the wakelock
reference on successful acquire.

libeffect: Fix enabled effect count calculation error

When switching from tunnel to arm effects, effect chain will be moved
from offload thread to mixer thread. During this procedure effect instance
is not destroyed, instead it's preserved and mounted onto new chain.

The migrant sequence is 1) disable instance -> 2) move to new effect
chain -> 3) enable instance again. However, the accumulated effect
enabled count is not decreased when effect instance is disabled.

As a result, LvmBundle_process() is only called once when Effect_process()
called twice, which causes input buffer get processed alternately and
glitch sound appears.

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.

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.

audio: Added lock during closing of direct output

- Lock is missing when direct output is closed in
  closeOutput_nonvirtual. As mDirectAudioTracks is
  being modified in this function, we need a lock
  here to avoid synchronization issues when it is
  accessed from other methods in AudioFlinger
- Fix is protect direct audio track specific block
  with mLock

audio: check voip input sample rate to allow voip direct output

It is possible that some voip applications request different sample
rates for input and output streams. Avoid opening of voip direct
output if the voip input is already opened with a different sample
rate.

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.

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.
