By adding the range data we can get successful handling of full range
color via custom FFmpeg output. Previously it would always default to 0
which would yield partial/limited output. Without the colorspace info
the output file is correctly tagged, but not undergone the actual
conversion.
The channel_layout API was overhauled by FFmpeg [1-5]. The previous
bitmask channel_layout is replaced by a struct ch_layout which combines
the number of channels, a bitmask and other infos.
The resampler needs to be updated whenever using swresample > 4.5.100.
This commit makes the necessary changes.

Add comparison check so that NaN is caught.
Comparisons with NaN always result in false.
NaNs cause problems later in audio encoder.
Note: may break with -ffast-math compiler flag.
Fixes#4885.
Since [1], avcodec/version.h is not included anymore in codec.h and
therefore is not included any more in avformat.h.
As a result, LIBAVCODEC_VERSION_INT is no longer defined. This commit
fixes the include.
Since obviously we can't ifdef the avcodec include by referring to an
avcodec version, we ifdef it with the avformat version which was bumped
at the same time [2].

Prior to this change, the audio thread roughly waits the time of
`AUDIO_OUTPUT_FRAMES`, and consecutively processes twice or more if the
latency is accumulated. This behavior causes fluctuation of timing to
output audio packets. This change introduces `os_sleepto_ns_fast` so
that the audio packets will be periodically output.
Rec. 2020 is really an SDR spec, but I think HDR10 made it okay to slap
PQ on it, call it an HDR spec. Rec. 2100 came along after and formally
allowed the use of PQ/HLG, so we should use 2100 instead.
When playing video, OBS can overflow and crash, or render video edges
incorrectly if the video resolution does not divide into 2 for trivial
chroma subsampling. This is fixed by rounding chroma plane sizes up
instead of down, and maintaining that through the video pipeline.
Similar to 315fbd6 and 6071098, ignore non-fatal errors during the
remux process. It's possible OBS itself writes a file that generates
these errors when remuxed.
As os_gettime_ns() gets large the current scaling methods, mostly by casting
to uint64_t, may lead to numerical overflows. Sweep the code and use
util_mul_div64() where applicable.

sse-intrin.h is a required header now, but the implicit path
breaks building addons once the headers are installed.
Fix this by making the path explicit.
