Otherwise it might be > buf_ptr in which case ffio_get_checksum()
could segfault (s->buf_ptr - s->checksum_ptr would be negative
which would be converted to something very big when converted
to unsigned for the update_checksum callback).
Fixes ticket #11233.

- proper pts for packets. leaving it blank leaves it up for guessing,
but the guess doesn't take seeking into account, causing weirdness.
- clamp to 0 when seeking to negative ts. libopenmpt docs are unclear on
this but not doing this causes an immediate EOF when seeking backwards
to the beginning in mpv.
- only set song duration and packet pts when they are non-negative and
in int64 range. NaNs count as out of range. this isn't a fix for any
specific issue but might be helpful still, and shouldn't break
anything.

Apparently files with milliseconds exist in the wild. And since it cost
nothing to support arbitrary number of digits, extend format to support
that.
Depending on number of digits, the time base of fractional part is
changing. Most LRCs use 2 digits and centiseconds base, but subs with 3
digits and miliseconds exist too.
Set internal time base to AV_TIME_BASE, which in parcitice allows to
hold microseconds with 6 digits. Totally artificial, but who knows maybe
someone wants that.

(setting to 100 as a reasonable compromise)
The change has caused regressions for many users and consumers.
Playlist reloads only happen when a playlist doesn't indicate that it
has ended (via #EXT-X-ENDLIST), which means that the addition of future
segments is still expected.
It is well possible that an HLS server is temporarily unable to serve
further segments but resumes after some time, either indicating a
discontinuity or even by fully catching up.
With a segment length of 3s, a max_reload value of 1000 corresponds to
a duration of 50 minutes which appears to be a reasonable default.

This blocks disallowed extensions from probing
It also requires all available segments to have matching extensions to the format
mpegts is treated independent of the extension
It is recommended to set the whitelists correctly
instead of depending on extensions, but this should help a bit,
and this is easier to backport
