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 33d18982fa03feb061c8f744a4f0a9175c1f63ab,
the commit that introduced the new packet-based bsf API, because with
this switch the allocations were no longer performed directly, but by
av_new_packet().

With 33d18982fa03feb061c8f744a4f0a9175c1f63ab, 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 dc99ee6b08
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 55f9037f38
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 780d7897a9
for ff_url_join(). This header became unnecessary when this function was
moved into a separate file in df9f22d42b.

libavutil/pixdesc.h has been included for av_get_pix_fmt_name() in
603b8bc2a1 and is unused since commit
2fb7501938 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
e7dd97b5d8cd6ea150446591f37a5946e8ab7cfb; it is unused since commit
b72a7b96f8 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 c26e58e32c
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
101e1f6ff90c3365bfde05469ae26d2ee7f71f3e, 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 ed7694d8cf to
d60a9f52eb.

riff.h has been added in 45da8124a0
because riff.h once contained declarations for (ff_)codec_get_tag().
This was changed in bfe5454cd2.

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.)
