(in my local tree 2 runs gave the same result with this but i had other
changes too)

This should not be needed, our AVParsers should do this
I do not have a testcase though, please help testing this and please
add fate tests if you can.

Fixes null pointer dereference
Testcase is simply a ffmpeg instance sending a stream to ffserver while another ffmpeg reads from it
This reverts commit 6f0a1710d7.
Since this is a C11 feature, it requires -std=c11.
Not actually used for anything yet, that will be added in the following
commits.
This merges libav commit 13f5d2bf75.

mythtv have problem with non-seekable dont write duration and filesize
and there have problem with some other server and player with 0 value
duation and filesize.
So add a flv flags to fix the ticket and make a choose for users.

give very bad quality for soxr resampler.
linear_interp is intended for using linear interpolation
between filter bank so quality will be better.
i guess this is misunderstood as 'do not use filter bank,
but directly interpolate linearly between samples'.

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

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
benchmark on exact_rational=on:linear_interp=on
