Audio improvements.

New supported samplerates: 8, 11.025, 12, 16 kHz.
Now 8, 11.025, 12, 16, 22.05, 24, 42, 44.1, 48 Khz are supported.
Unsupported samplerates are sanitized to the closest samplerate for all encoders.

Samplerates < 32 kHz are now forbidden for AC3 encoding (sanitized to 32 kHz). Most AC3 decoders don't support such samplerates.

New upmixing: 3.0 (Front Left, Right & Center) can now be upmixed to 5.1 to preserve the center channel.

New mixdowns:

6.1 (Front Left, Right & Center, Surround Left, Right & Center, LFE)
7.1 (Front Left, Right & Center, Surround Left & Right, Rear Left & Right, LFE)
-> available to Vorbis & FLAC encoders for compatible input channel layouts
7.1 (Front Left, Right & Center, Front Left & Right of Center, Surround Left & Right, LFE)
-> available to AAC encoders (ca_aac, ca_haac, faac) for compatible input channel layouts

Mono (Left  Only): Stereo to Mono by discarding the Right channel
Mono (Right Only): Stereo to Mono by discarding the Left  channel
-> available to all encoders for non-Dolby Stereo input

The "6-channel discrete" mixdown becomes "5.1 Channels".

New bitrates: 960 - 1536 Kbps.
This lets users work around poor audio quality in crappy encoders by throwing more bits at them.

Bitrate limits have been re-worked and re-tested for all encoders.
