fa3eba16446cc8f2f5e2dfc20d86a49dbd37299e 30-Aug-2013 Jean-Michel Trivi <jmtrivi@google.com> 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.

* AAC-Encoder

- Remove source snippets related to unsupported frame length of 960.
- Adjust minBits initialization for disabled VBR configuration.

- Revise encoder parameter restrictions: "Error Resilient(ER) AAC Low Complexity"
is not supported. Where the AAC part of the FDK encoder threw an
initialization error, now the aacEncoder_SetParam() returns an error
before initialization if the application tries to configure this
audio object type.
