avformat/utils: estimate_timings_from_pts - increase retry counter, fixes invalid duration for ts files with hevc codec

Fixes a mpegts file with hevc that fails estimating duration. Increasing number of
retries fixes the issue.

This matches the Libav signature and simplifies merging future changes.

All encoders set pts and dts properly now (and have been doing that for
a while), so there is no good reason to do any timestamp guessing in the
muxer.

The newly added AVStreamInternal will be later used for storing all the
private fields currently living in AVStream.

It will be needed in other functions.

The reasoning for setting it to zero only applies to demuxing.

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.
