libstagefright: Wrapper for FLAC CSIM decoder

A new FLAC decoder is being used to decode 24 bit clips with
very high sample rate (192kHz) and this code is a wrapper to that decoder.
The decoder will be used only if the extended extractor is invoked.

libstagefright: Optimize the wrapper for FLAC CSIM decoder

Move dlsym calls to constructor and do all memory allocations
only once to avoid fragmentation of heap.

Also add support to handle multichannel PCM from the decoder.

libstagefright: Modify the path of FLAC headers

The location of the headers of the FLAC CSIM library has changed.
Modify the include path to reflect the right location.

libstagefright: Add support for FLAC superset clips

Memory requirements for FLAC superset content are high as each
channel can contain upto 64k bytes. Redefine the macros to meet
these requirements.

Also initialize the decoder to give data in configurable bitWidth.
Currently, only 16 bit output is supported though.

libstagefright: Enable ACodec path for QTI FLAC solution

Use the OMX component of Google's RAW decoder for FLAC codec and
setup NuMediaExtractor to extract PCM samples from FLACDecoder.

  only use video hardware codec for nuplayer

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

stagefright: ACodec: add an extra buffer to ANW's BUfferQueue

Add an extra min-undequeued buffer to ensure framework (ACodec)
has a free buffer to dequeue rather than wait for the queued buffer
to be displayed
This improves the performance of playback via nuPlayer.

stagefright: Increase buffers with nativewindow

To avoid frame-drops due to latencies in rendering.

If (minUnDequeued) buffers are caught in display pipeline,
dequeueBuffer will block, which delays subsequent queuebuffer,
and this repeats until a buffer is canceled (frame drop).
This issue is more prominent with high resolution content
on secondary displays.

Adding additional buffers increases the stagger in display
and makes finding a free buffer more likely

Solved problem with hanging decode call

Improved error handling in Mediaplayer service,
stops decode from hanging when player->start()
fails.

stagefright: Query PCM output format and fix bugs

 * Ask the decoder about it's PCM output format instead
   of hardcoding exceptions.
 * Google's AAC codec fails on main profile, skip it.
 * Don't crash on unsupported Windows Media files.
