audioflinger: Allow FAST tracks for any supported sample rate

stagefright: More high-resolution audio support

 * Clean up the "error driven" fallback code we had before and
   reconfigure components if the output bit width needs to change
   (a2dp/usb fallback).
 * Decode various formats (AC3/DTS/EAC3) which output floating point
   samples using FFMPEG, which will output 24-bit PCM for us.

stagefright: Use multiaac decoder for multiaac :)

 * Fix the channel count and use the non-OMX multiaac codec.
 * This fixes a DSP crash with certain files.

audio: Audio resampler support for 192Khz playback

-Current AudioResampler limits input sampling rate to be
maximum of twice of output sampling rate to downsample.
The output sampling rate being 48khz, maximum input sampling
rate that be supported is 96khz.
Support is added to use qti resampler for playback upto 192khz.

stagefright: Resolve turf war between FFMPEG and mm-parser

 * There is overlap between the supported codecs, and the extractors
   generally do the right thing. The current code will blindly call
   into the FFMPEG specific functions when some QC codec should
   be used though, so add checks on the component name first.
 * This resolves hitting asserts when using hardware WMA/WMV codecs.
 * Also add a contraint to block the VC1 codec from try to play ancient
   WMV formats, as it will fail.
