The speex specification does not seem to restrict these values, thus
the limits where choosen so as to avoid multiplicative overflow

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.

Note, this temporarly drops the ability to set ffmpeg encoder debug and flags2 via ffserver.conf

This reverts parts of c1658257. 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.

Rename hz in af_apulsator.c and avf_showspectrum.c as hertz.

The aix header sys/m_param.h defines hz as __hz.

The maximum number of references is 16, so the index value cannot
exceed 15.

Really should have done this last time. It should provide consistency
across our allocations and frees.

This should deal with some false positives, but might lead to
more of them depending on whether it realises that av_freep()
wraps av_free() or not.
