stagefright: update support for omap3 decoders and encoders

OMAP3 uses 2 decoders, 720P.Decoder and Video.Decoder.

720P.Decoder is proprietary OMAP3 decoder from ITTIAM. Only
one instance of the 720P decoder can run at a time due to memory
restrictions (512MB) and it's quite slow at thumbnail generation
and it's resource hungry.

Video.Decoder is opensource and could support WVGA resolutions.
It only supports baseline profile and max level 31 for AVC, but
could run 4 instances at the same time and is quite fast especially
for watching WhatsApp videos :P

Using the 720P decoder for low resolution videos is not optimal and
trying to use the Video.Decoder for videos other than Baseline profile
will crash the entire DSP and would require a reboot. Currently
stagefright uses codecs in the order they appear in media_codecs.xml
without querying the supported level and profile from the decoder,
due to which wrong codecs are selected causing problems.

Similarly there are 2 encoders, 720P.Encoder and Video.Encoder. They
support different resolutions and should be used selectively.

This patch has been forward ported from Gingerbread branch.

libstagefright: Fix incorrect comparison of mimetype

'sizeof' is used to calculate length of string constant which returns
size of pointer to string constant. This causes comparison of only
four characters of mimetype. By using strlen, entire mimetype string
is compared - which returns correct result.

 libstagefright: Use channel count if channel mask is zero.

-If the channel mask which is part of the meta data is zero use
 a valid channel count to update the channel mask.
-PCM offload playback for wav clips fails for some clips because
 channel mask part of the wave header is zero.

libstagefright: Fix app crash during pcm offload playback

 -ANR is seen with trick mode operations during
  pcm offload playback.
 -If Player issues the read request to omx client while omx client is
  in pausing state, it moves the client to executing state if variable
  mPasued is true and it never returns from pause.
 -Do not set the variable mPaused to true while it is in pausing state.

libstagefright: mpeg2ts: Ignore continuity_counter discontinuity

The continuity counter is incremented for each ts packet. Any lost
packet results in a discontinuity, and the stock parser flushes the
current frame data leading to corruption if an I-frame is lost.
Avoid flushing on discontinuity to prevent some of this corruption.

Either timescale or duration must be modified to show the correct

NuPlyer:RTSP: Fix some issues while seeking RTSP source

- Clear the obsolete packets after sending the seek request
- Stop rendering any obsolete frames while seeking
- Stop queueing any obsolete units to source while seeking
- Without this patch, the process-bar will return to
  the previous playback position, and stay at this position
  until the seek operation finish.
  Then, the process-bar will go to the seek position, and go
  forward according the playback of the clips.
- Without this patch, in some platform (based on Q6), seek
  operation will cause several green frame.

libstagefright: Customize AV sync behavior

Based on the property, whenever video decoder takes more time
for decoding and causing few consecutive frame drops to maintain
the AV sync, then disable AV sync till it recovers.

This change will avoid freeze whenever any video clips out side
of the supported spec are being played though audio and video
are out of sync.
This improves user experience

stagefright: Add a prefetching source

Add a prefetching source which pre-fetches buffers from
upstream source in a low priority context.
This decouples the caller of read() from the underlying source,
effectively making read() non-blocking as long as there are
already prefetched buffers available.

 -Do not skip the sink stop if renderer position is EOF and ignore
  seek if seek time is same as player position.
