Clang is not able to eliminate the reference to ff_spdif_probe() when
there is a goto target in the same block and optimization is disabled.
This fixes the following build failure on OS X:
./configure --disable-everything --disable-doc \
--enable-decoder=pcm_s16le --enable-demuxer=wav \
--enable-protocol=file --disable-optimizations --cc=clang
make
...

MPEG Audio frame header must be 4 bytes. If we fail to read
4 bytes bail early to avoid Use-of-uninitialized-value msan error.

The demuxer doesn't fill the defaults if the master isn't present.
This results in codecpar->color_space being set with a value of
zero (RGB) on such files.

This is a bit messy as codecar does not support AVOptions so we need
to use AVCodecContext where AVOptions are required and copy back and forth.

This would be simpler if codecpar supported AVOptions
modern ffserver should be unaffected by this, older ffserver which required the
muxer to directly access the encoder could have issues with this, but this
direct access is just wrong and unsafe

This accesses the private encoder context, it should not be used by
the current ffserver it may affect old ffserver versions but i believe
there is consens that accessing the private encoder context from the muxer
is completely wrong.

This reverts parts of c16582579b. The hard
coded 30 seconds are a lot, and finishing the seek can takes several
seconds when the source is on a network share. Remove this code
entirely, because it does more bad than good.
