Fixes a memory leak when using genpts

This fixes a memory leak when side-data is present.

Make it return an error and check its return value when it is used.
Simplify the usage by calling `av_packet_ref` internally when needed.

`av_packet_unref` matches the AVFrame ref-counted API and can be used as
a drop in replacement.

Deprecate `av_free_packet`.

And drop the av_dup_packet from the input_thread.

Note that convergence_duration had another meaning, one which was in
practice never used. The only real use for it was a 64 bit replacement
for the duration field. It's better just to make duration 64 bits, and
to get rid of it.
