Fixes null pointer dereference

Testcase is simply a ffmpeg instance sending a stream to ffserver while another ffmpeg reads from it

This reverts commit 6f0a1710.

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 13f5d2bf.

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'.
