Currently, AVHWAccels are looked up using a (codec_id, pixfmt) tuple.
This means it's impossible to have 2 decoders for the same codec and
using the same opaque hardware pixel format.
This breaks merging Libav's CUVID hwaccel. FFmpeg has its own CUVID
support, but it's a full stream decoder, using NVIDIA's codec parser.
The Libav one is a true hwaccel, which is based on the builtin software
decoders.
Fix this by introducing another field to disambiguate AVHWAccels, and
use it for our CUVID decoders. FF_CODEC_CAP_HWACCEL_REQUIRE_CLASS makes
this mechanism backwards compatible and optional.
cuvid.c is used by Libav's CUVID hwaccel. Resolve the conflict and
avoid future merge problems by renaming our decoder.

This will be useful in the CUVID hwaccel. It should also eventually
replace current decoder-specific mechanisms used by various other
hwaccels.
Merges Libav commit 704311b294.
This gives FFmpeg libs a field that they can freely and safely use.
Avoiding the need of wrapping of a users opaque_ref field and its issues.

The user-supplied value for timecode_rate in drawtext is rounded
to nearest integer. So, a supplied value of 0.49 or lower is rounded to 0.
This throws a misleading error message which says "Timecode frame rate must be
specified". Changed message to account for values under one.
Also noted supported framerates for drop TC.

The spec is correct, it does list these layouts as having rear speakers.
Questionable how many decoders correctly interpret those correctly since
side is way more popular.
Also fixes fate-aac-yoraw-encode.

This commit implements support for PCE (Program Configuration Elements) in the
AAC encoder, and as such allows for encoding of channel layouts not present
in the presets defined by the spec (which only lists the 8 most common ones).
This has been a highly requested feature and is also the first open source encoder
to support this many layouts.
Many thanks to pkviet <pkv.stream@gmail.com> who implemented support for and
verified all channel layouts.
Since non-Haar wavelets need to look into pixels outside the frame, we
need to pad the buffer. The old factor of two seemed to be a workaround
that fact and only padded to the left and bottom. This correctly pads
by the slice size and as such reduces memory usage and potential
exploits.
Reported by Liu Bingchang.
Ideally, there should be no temporary buffer but the encoder is designed
to deinterleave the coefficients into the classical wavelet structure
with the lower frequency values in the top left corner.
