There is really no need for two aac wrappers, we already have
libfdk-aac which is better. Not to mention that faac doesn't
even support HEv1, or HEv2. It's also under a license which is
unusable for distribution, so it would only be useful to people
who will compile their own ffmpeg, only use it themselves (which
at that point should just use fdk-aac).

* Multichannel support for TrueHD is experimental
There should be downmix substreams present for 2+ channel bitstreams,
but ffmpeg decoder doesn't need it. Will add support for this soon.
* There might be lossless check failures on LFE channels
* 32-bit sample support has been removed for now, will add it later
While testing, some samples gave lossless check failures when enforcing
s32. Probably this will also get solved with the LFE issues.

lavc/movenc rely on avpriv_dnxhd_parse_header_prefix declared by
dnxhddata.h since e47981dab7.
Fixes a missing symbol error in lavc/movenc if the dnxhd encoder is not
enabled.
Still much left to optimize, but it provides a significant performance
improvement - 10% for 300Mbps (1080p30), 25% for 1.5Gbps (4k 60fps) in
comparison with the default implementation.

There is no real advantage to listing some codecs or subsystems
separately simply because they are somehow "hw-accelerated", on the
contrary it makes them harder to find than in a plain alphabetically
ordered list.
Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.
This is added in 10.11, so we add a #define when building against older SDKs.
The decoder actually supports 7.1-channel eac3, but since the parser only
reports 6 channels, we end up decoding the 5.1 downmix (same as the internal
decoder) for now.
