stagefright: Increase raw codec buffer size

 * Enlarge the buffer to handle up to 6 channels of 32-bit data.
 * We should probably do this dynamically in the future.

AudioTrack: Reject offloading for non-music streams

Reject AudioTrack initialization if called with non-music
stream type (or attribute) but with AUDIO_OUTPUT_FLAG_COMPRESS_OFFLOAD.

This will allow the client to fall back to SW decode or
deal with the error appropriately.

stagefright: Fix metadata/message conversion issues

 * Remove duplication of code between ExtendedCodec and FFMPEGSoftCodec,
   just call into ExtendedCodec and properly ifdef QCOM-only parts.
 * Fix CSD not being converted when AV_ENHANCEMENTS wasn't set- this
   was breaking the software video codecs on Hammerhead.
