Adds call to x265_param_apply_profile after x265_param_parse.
Added as private option since HEVC profiles other than
Main, Main 10 and MSP in AVCodecContext are consolidated in a single
constant.

This should save quite a bit of space if either has been disabled for size reasons.
Could just check if the encoding flag is set during runtime on every single location,
however the overhead of branch misses would somewhat decrease performance.

Due to a somewhat high volume of complains, phase inversion has
been made optional with RFC8251. This allows for better bass
frequency response when partially downmixing to play on systems
with an LFE speaker.

This decoder-side change, introduced in RFC 8251 (section 9), slightly
improves the decoded quality of 16kbps speech in Hybrid Mode.
Differences can be seen/heard in testvector05.bit, testvector06.bit,
and testvector12.bit in the RFC 6716/8251 testvectors found here:

The existing logic overrides container metadata even in cases where the
container metadata must be trusted (e.g. HDR). The original spec had no
provision for specifying color volume, so many files rely on the
assumption of Rec. 709.
An update to the spec included a 'clv' field for explicitly signaling
that the container should be trusted in an existing bitfield in the
frame header, but the default of 0 from old encoders forces Rec. 709,
which would break any HDR stream. Because there is no place in DNxHR for
specifying a transfer function, DNxHR HDR files must include
container-level color information.
This patch maintains the existing behavior of choosing the 709 over the
601 matrix when container-level information is missing, and allows
container-level information to win if present.

webm usually has invisible superframes merged with normal frames.
(vpxenc muxes them in this form, which is evidence enough that this is
the standard webm packet format. It's rather unclear whether ffmpeg is
even allowed to remux them with split packets.)
The vp9 decoder needs them to be in separate packets for multithreading
to work. Add the BSF to the decoder, so the conversion happens
automatically.
This contains the important part of fa1749dd34c55fb9, which
was apparently skipped in commit d417e95af76. This restores Libav API
compatibility.
In function process_output_surface(), the return value is 0 on the path
that av_mallocz() returns a NULL pointer. 0 indicates success, which
deviates from the fact. Return "AVERROR(ENOMEM)" instead of "0".
