The ad-hoc libmfx setup code is the only place its still used, so move it
into that file.

This can support encoders which want frames and/or device contexts.  For
the device case, it currently picks the first initialised device of the
desired type to give to the encoder - a new option would be needed if it
were necessary to choose between multiple devices of the same type.

Also move it into a dedicated function in the hardware file.

These encoders all accept VAAPI surfaces in a hardware frames context.

All of these encoders can accept libmfx surfaces directly in a hardware
frames context, or they can accept software frames if a suitable device
is supplied to use.

This already applied to decoders as well as hwaccels, and adding encoder
support was going to make the name even more inaccurate.

This fixes tests on 32 bit x86 mingw with clang, which uses x87
fpu by default.

In this setup, while the get_expected function is declared to
return float, the compiler is (especially given the optimization
flags set) free to keep the intermediate values (in this case,
the return value from the inlined function) in higher precision.

This results in the situation where 7.28 (which actually, as
a float, ends up as 7.2800002098), multiplied by 100, is
728.000000 when really forced into a 32 bit float, but 728.000021
when kept with higher intermediate precision.

For the multiplication case, a more suitable epsilon would e.g.
be 2*FLT_EPSILON*fabs(expected_output), but just increase the
current hardcoded threshold for now.

libavutil/mem.h is unneeded since 33d18982,
the commit that introduced the new packet-based bsf API, because with
this switch the allocations were no longer performed directly, but by

With 33d18982, the commit introducing
the new packet-based bsf API, a new buffer was no longer allocated
directly, but via av_new_packet(), so that libavutil/mem.h was no longer
needed.

Moreover since commit dc99ee6b
av_packet_make_writable() is employed which copies the data in case it
is unavoidable so that string.h is no longer used (it was used for
memcpy()).

mux.c was split from utils.c in 55f9037f
and during this split all headers were simply copied without checking if
they were only needed in the part that stayed in utils.c (or whether
these haeders were needed at all). As a result quite a lot of headers
in mux.c are unnecessary. This commit removes them.

stdarg.h has been included in 780d7897
for ff_url_join(). This header became unnecessary when this function was
moved into a separate file in df9f22d4.

libavutil/pixdesc.h has been included for av_get_pix_fmt_name() in
603b8bc2 and is unused since commit
2fb75019 that removed the stuff belonging
to FF_API_FORMAT_PARAMETERS. Notice that this file still uses
AV_PIX_FMT_NONE and that therefore the header libavutil/pixfmt.h has
been included (this header is included in pixdesc.h as well as also in
libavutil/internal.h which is also included).

libavutil/time_internal.h has been included for gmtime_r() in commit
e7dd97b5; it is unused since commit
b72a7b96 which basically moved the code
making use of gmtime_r() to libavutil/dict.c to use in
avpriv_dict_set_timestamp().

audiointerleave.h has been added in c26e58e3
because of ff_interleave_compare_dts() (at that time the muxing code
was not split from utils.c yet); said function became static in commit
101e1f6f, making this header redundant.

metadata.h has been mostly included for what now resides in
libavutil/dict.h. The stuff that now resides in metadata.h has only been
used briefly: From commits ed7694d8 to
d60a9f52.

riff.h has been added in 45da8124
because riff.h once contained declarations for (ff_)codec_get_tag().
This was changed in bfe5454c.

The documentation of av_dict_set() states that values >= 0 indicate
success, whereas av_packet_unpack_dictionary() implies that return
values > 0 are impossible. So only forward the return value of
av_dict_set() in av_packet_unpack_dictionary() on error.

(Btw: av_dict_set() does currently not return values > 0.)
