These fields correspond to the actual audio data in the AVFrame, and should always be set (otherwise, we must submit a bug report to libav).

- 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)

Not sure why I thought this was needed.
Apologies if I break anything.

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.

Such packets can result from samplerate or other types of audio conversion.

the code I added to it really belongs in hb_audio_resample.

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.

Fixes an issue in assembly code that could result in very poor performance when encoding with x264 & AC3 Passthru.
Thanks to our John Stebbins for finding the cause of the bug, and to x264 & Libav developers for fixing it.
Miscellaneous other fixes and improvements, including multichannel Apple Lossless audio decoding support.
Also, clean up our Libav configure options (group things together, disable all hardware accelerations with one switch instead of individually, and disable building the unused avfilter library).

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