Encoder 7.1 support
* AAC-Encoder - Add 7.1 rear surround and 7.1 front center support to supported encoder channel modes. Change max channels from 6 to 8 and add 7.1 configuration to bandwidth and channel mapping functions.

Changed max channels from 6 to 8. Modified file(s): libSBRenc\include\sbr_encoder.h libSBRenc\src\sbr.h libSBRenc\src\sbr_encoder.cpp libSBRenc\src\sbr_ram.cpp * Transport-Encoder - Add 7.1 channel configuration to audio specific config writer in transport encoder library. Modified file(s): libMpegTPEnc\src\tpenc_asc.cpp libMpegTPEnc\src\version * SYS-Library - Add 7.1 channel modes to CHANNEL_MODE description. Modified file(s): libSYS\include\FDK_audio.h libSYS\src\genericStds.cpp Bug 9428126 Change-Id: Ide53583aa8e03df4537b98db80740dfe0e7a9e0f
