stagefright: add an extra buffer to ANW's BUfferQueue

Add an extra buffer to ensure video player has a free buffer to
dequeue rather than wait for the queued buffer to be displayed.
Enable logs to indicate number of buffers allocated.

NOTE: This is not needed for 30fps content on 60fps panel, But
making this change regardless for all framerates till root-cause
is identified in SF

libstagefright: Filewrite in seperate thread for single video track

For files with single video track, the filewrite() and OMXRead()
operations are happening in the samethread. It impacts the
recording performance.

Hence moving filewrite to seperate thread for files with single
video track.

av: Additional ifdefs for QCOM DirectTrack

 * Tunnel and LPA mode on legacy QC devices requires the DirectTrack
   code path, which going forward has been deprecated.
 * In order to properly support QC features on 8974, this needs broken
   out in order to not cause problems on new devices.
 * With this patch, QCOM_HARDWARE will enable features common to all
   QC platforms (including legacy), and legacy support will
   automatically be enabled based on the use of driver variant and
   value of BOARD_USES_LEGACY_ALSA_AUDIO.

audioflinger: OffloadThread state fix

When switching from one offload session to another that
reuses the same offload output, audio HAL is paused & flushed in
preparation for the new track.

OffloadThread must reset mHwPaused to allow proper state transitions
for the second track.

AudioMixer: Remove tracks from enabledTracks after reseting outTemp

If any track goes through AudioMixer::process__genericNoResampling, and
its getnextbuffer returns NULL, Then that track is removed by AudioMixer
from enabledTracks.

Thus if all tracks getnextbuffer return NULL, Then this function doesn't
reset outTemp and last buffer in AudioFlinger's mMixBuffer will be
repeated and noise is observed.

Remove tracks from enabledTracks after reseting outTemp to zero, so that
process__genericNoResampling will reset outTemp and noise won't appear.

and rotation hint to overcome the limitation.

audio: Add pause support for hardware omx component

-ADSP doesn't enter sleep state after wma playback is paused
and power suspended.
-No support for NT session pause in case of hardware component.
NT session need to be paused to put ADSP into power collapse.
-Add support of pause in stagefright to ensure device enters
suspend mode. Also add intermediate states to avoid concurrency
issues between read and pause.

libstagefright: Update handling of SBR explict siganlling

In case of SBR explict signalling in the bitstream, the core
AAC sample rate is overwritten by extension sample rate.
HW AAC decoder relies on core sample rate to parse the
bitstream when supplied in raw format.
Do not overwrite core sample rate but store it as separate
field in the meta data.
