Use proper integer variables.

avcodec_open2() also called the AVCodec's close function if an error
happened before init had ever been called if the AVCodec has the
FF_CODEC_CAP_INIT_CLEANUP flag set. This is against the documentation of
said flag: "The codec allows calling the close function for deallocation
even if the init function returned a failure."

E.g. the SVQ3 decoder is not ready to be closed if init has never been
called.

This reverts commit 5bbf58ab.

The setparams filters are not hwframe aware, so the default context
passthrough behaviour is needed to allow using them with hardware frames.

In the VT encoding insertion by FFmpeg,
and vtenc_q_push is callback to add the encoded data
to the singly linked list group in VTEncContext,
and consumers are notified to fetch it.
However, because it first informs consumers of pthread_cond_signal,
and then inserts the data into the tail,
there is a multi-thread safety hazard.

don't wait when flushing data.

A common pattern e.g. in libavcodec is replacing/updating buffer
references: unref old one, ref new one. This function allows simplifying
such code and avoiding unnecessary refs+unrefs if the references are
already equivalent.

Allow setparams to be used with hw backed frames and
avoid an assertion failure in avfilter_config_links.

Add AC-3/EAC-3 to allowed extensions file list.

It seems that in files where the BASF block isn't first, v1.1 ASF streams are
allowed to be non-22050. Either this format is really inconsistent, or
FX Fighter and Croc just ignored the sample rate field, requiring the v1.1
restriction in the first place.

This bumps the version to 1.2 in these streams so they're not "corrected".
