- encavcodecaudio: use libavresample directly (instead of via the hb_audio_resample wrapper), and add support for planar output
- hb_audio_resample: add support for planar input
- hb_audio_remap: add support for planar input
- deca52: output planar float samples (no re-interleaving)

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.

hb_audio_resample_init().
Unlike hb_audio_remap, hb_audio_resample will never be used in situations where we don't have a mixdown.

liba52.
Add support for center & surround mix levels to hb_audio_resample.
This allows us to support upmixing all audio sources. For sources that have at least 2 front and one back or side channel(s), allow upmixing to 5.1:
3.0/3.1 (2 front and 1 back channels)
4.0/4.1 (3 front and 1 back channels)
4.0/4.1 (2 front and 2 side channels)
5.0 (3 front and 2 side channels)

Since switching to libavresample for audio mixing, our output
volume levels have been reduced because libavresample
does mix level normalization by default. This change
applies a patch to libav to allow us to disable this behavior
and adds a new field to hb_audio_config_t to allow the
hb frontends to control this feature.

Avoids having code that's mostly identical in multiple files.
