kill warnings if unused

Solve 'lost synchro' warnings when using a file input. The warning was
triggered by the functions GetFirstPCR(), CheckPCR() and GetLastPCR().
They searched for a TS packet which contains a PCR but did not take
the TS packet size boundarys into account. By rounding to the nearest
p_sys->i_packet_size this warning was resolved.

And when it was successfully added

Also don't care input fps and only calculate what should be the
next output pts. We anyway define output fps to be either 25fps
or input fps if it's available.

This should help to eliminate skips/visual artefacts on video if
there is small skips in input. And output constans fps from transcode.

Fixes #10453 for me

Prints dts, segment number, length, difference to previous dts and md5
of block.

with prefix-option you can give prefix to print in stats-line, so you can
add stats module multiple times with different prefixes. Output to file
is given with output parameter.

Skeleton handling does early write of some headers,
and then skipped flagging them.
