Just including icodecapi.h + codecapi.h apparently misses some bits,
that MSVC doesn't complain about, but Clang does. Thus add a missing
header to the custom hacky include path (required for keeping
ICodecAPI visible when building in UWP mode, as it is intended to).
The issue in Windows SDK headers about ICodecAPI availability in
UWP/app mode has been reported upstream at
https://developercommunity.visualstudio.com/content/problem/1037125/icodecapi-not-visible-when-compiling-in-uwp-mode.html,
and later also filed in Feedback Hub (which can't be linked to
externally).

This change makes it possible for child encoders to define custom profile
option names which can be used for setting the AVCodecContext->profile.
Also rename unit name to something rather unique, so it won't be used elsewhere.

The framerate field is the one users are supposed to set, but not
all users might be setting it, so it might be good to fall back
time_base in that case.

EAGAIN is returned when input is provided but can't be consumed. The filtering
process is unaffected in this case, and the function will be able to consume
new input after retrieving filtered packets with av_bsf_receive_packet().
Remove the line about empty packets never failing added in
41b05b849f while at it. Even if it's currently
the case, it unnecessarily constrains the API and could be changed in the future
in case it needs to be extended.
The user should always check for errors and never expect a call to never fail.

If the RPS we are predicting from has maximum size then at least one of
the pictures in it must be discarded before adding the current one.
Also revert 588114cea4, which added
now-redundant checks for the special case of a too-large RPS with all
pictures being in the same direction from the current one.

This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3.
This is based on top of an original patch by wm4
<nfxjfg@googlemail.com>. The original patch supported both encoding
and decoding, but this patch only includes encoding.
The patch contains further changes by Paweł Wegner
<pawel.wegner95@gmail.com> (primarily for splitting out the encoding
parts of the original patch) and further cleanup, build compatibility
fixes and tweaks for use with Qualcomm encoders by Martin Storsjö.

It's the correct dedicated capability reported by supported encoders.
Otherwise, the frame thread path will be used for unsupported encoders
like r210 for no gain.

The h264_nvenc and hevc_nvenc encoders aren't respecting the framerate in the codec context.
Instead it was using the timebase which in our use-case was 1/1000 so the encoder was behaving
as if we wanted 1000fps. This resulted in poor encoding results due to an extremely low bitrate.
Both the amf and qsv encoders already contain similar logic to first check the framerate before
falling back to the timebase.

Hook up the x86 (mmx and sse) versions of get_pixels to this

Set DEPRECATED flag to option cabac, replace with coder. The
priority logic is:
1. s->coder; then
2. avctx->coder_type; then
3. s->cabac.
Change the default option to -1 and allow the default cabac to be
determined by profile.
Add FF_API_OPENH264_CABAC macro for cabac to remove this option after
LIBAVCODEC_VERSION_MAJOR = 59.

And determine the profile with following priority:
1. s->profile; then
2. avctx->profile; then
3. s->cabac; then
4. a default profile.
This seems more natural in case user somehow sets both avctx->profile and
s->profile.
