frameworks/av: enable voip flag based on channelcount

voip flag should be enabled based on channelcount instead of
channelmask. Some of voip apps like viber may not use
AUDIO_CHANNEL_OUT_MONO but still configures to single channel
like by using AUDIO_CHANNEL_OUT_FRONT_CENTER.

audio: fix meta MIME type failure in MPEG4Writer

- MIME type info included in source->getFormat()
  is not updated properly because only temp
  variable is updated in AudioSource::getFormat().
  MIME type string contains garbage value and it
  results in invalid audio formats.
  MPEG4Writer returns ERROR_UNSUPPORTED and tunnel
  mode recording with 3gpp format fails
- Fix this issue by assigning return value of
  getFormat() to a local variable, and check the
  return value of findCString.

audioflinger: Fix for removing noise while resuming playback after pause

-Issue: While resuming playback after pausing and seeking to backward,
there is a noise.
-Rootcause: When Resuming a Playback after Pausing and seeking,
AudioResampler's reset() function is resetting their member
variables but derived classes' s member variable are not resetting.
This is causing a noise in Playback because AudioResamplerSinc,
AudioResamplerOrder1 and AudioResamplerCubic's member variables
pointing to some previous state/values.
-Fix: To reset the derived class member variables,
override the reset function in all the derived classes.

libstagefright: Fix to free buffers in error scenarios

MediaBuffer objects are not freed if component transition from
IDLE->EXECUTING or EXECUTING->LOADED fails (or if the
OMX_CmdComplete messages are dropped due to an earlier error)
Additionally with native buffers, the corresponding
ANativeWindowBuffers are not cancelled back in the above scenarios.

libstagefright: Add 2 APIs (suspend and resume) in Mediaplayer

- API:suspend() will just pause the player and release all the decoders
  instead of release the whole player
- API:resume() will just init the decoders again
- Add a check in onVideoEvent()
  to make sure the first seek operation will seek the next i-frame

libstagefright: Add fix for mpeg4 data partition clips

- QC firmware does not support mpeg4 clips with data partition,

- Add logic in OMXCodec to parse the VOL header passed from
  QC parser to OMXCodec through kKeyRawCodecSpecificData
  for data partition bit and fallback to software codec if it
  is found.

libstagefright: Checks before freeing buffers on a port

- OMXCodec calls dequeueBuffer on the NativeWindow in a loop
  and registers output buffers with the OMX component.
- If a dequeueBuffer fails, the buffers already registered
  with the OMX component were not getting freed laeding
  to a memory leak.
- On an error, check state of OMXCodec before freeing buffers on a port.

-Issue: Mediaserver crash is observed in direct track functions.
