The subfile protocol treats an end of 0 as meaning "until EOF"; this got
implemented by simply setting the end to INT64_MAX. But seeking relative
to EOF or AVSEEK_SIZE seeking hasn't been adapted; the result is that
e.g. the duration of transport streams isn't correctly determined when
this option is used. This is fixed in this patch.

currently master playlist and subtitle playlist creation does not use
temporary files even when temp_file flag is set. Most of the use cases
it is not a problem because master playlist creation happens once on the
beginning of the whole process. But if master playlist is periodically
re-created because of master_pl_refresh_rate is set, non-atomic playlist
creation may cause problems in case of live streaming. This patch
correct this behavior by adding this functionality.

Commit 31f9032b added the audio_preload feature; its goal is to
interleave audio earlier than the rest. Unfortunately, it has never ever
worked, because the check for whether a packet should be interleaved
before or after another packet was completely wrong: When audio_preload
vanishes, interleave_compare_dts returns 1 if the new packet should be
interleaved earlier than the packet it is compared with and that is what
the rest of the code expects. But the codepath used when audio_preload is
set does the opposite.
Also fixes potential undefined behaviour (namely signed integer
overflow).
