This dubious behaviour in nvenc was finally removed by nvidia, and
as we refuse to run on anything older than 7.0, we don't need to
keep it around for old versions.

GnuTLS in combination with gcrypt has been deprecated since 2010.

Also add a missing avcodec.h #include in the movie filter.

floats are not necessarily normalized, so a normalized softfloat needs
MIN_EXP lowered by 23 to cover that range.

Otherwise the codec context and codecpar might disagree on the codec id,

The warning has false positives but our asm does not trigger it. For
new code false positives can only be avoided by changing the register
allocation.

separate dsp.resample to dsp.resample_common and dsp.resample_linear
and choose to call faster resample_common even when linear_interp=on
when c->frac and c->dst_incr_mod are both zero

speed up resampling when exact_rational and linear_interp are both
enabled because exact_rational force c->frac and c->dst_incr_mod to
be zero when soft compensation does not happen

Use correct variable for simple and complex filtergraphs.

This disables warnings about potentially uninitialized local pointer
variables.  Disabling the warning is in line with what we do for gcc.

This eliminates a handful of warnings at every inclusion of the header.

These functions are not available on mingw32ce.

The rtmpdh code can use crypto libraries which may require
a process global init. (gcrypt is one of the libraries
where the rtmpdh test code can fail if global init hasn't been
done, depending on gcrypt version.)
