Michael NiedermayerandMartin Storsjö a4fec9a7ea rtmppkt: Check for packet size mismatches 
When receiving fragmented packets, the first packet declares the size,
and the later ones normally are small follow-on packets that don't repeat
the size and the other header fields. But technically, the later fragments
also can have a full header, declaring a different size than the previous
packet.

If the follow-on packet declares a larger size than the initial one, we
could end up writing outside of the allocation.

This fixes out of bounds writes.

Michael NiedermayerandMartin Storsjö f126365cda mov: Fix parsing short loci 
Previously, we required the minimum number of bytes required for

notes fields, but do require an altitude field (which currently isn't
parsed). This matches the initial length check at the start of the function
(which doesn't know about the variable length place field).

Michael NiedermayerandMartin Storsjö 1384df6419 lavf: Add an option for avoiding negative timestamps 
This is the same logic as is invoked on AVFMT_TS_NEGATIVE,
but which can be enabled manually, or can be enabled
in muxers which only need it in certain conditions.

Also allow using the same mechanism to force streams to start
at 0.

Michael NiedermayerandMartin Storsjö 72f801619a movenc: Adjust edit lists to trim out parts of tracks with negative pts 
This makes sure that audio preroll for e.g. AAC is signaled correctly.

Previously we only wrote the edit list correctly if we had negative
dts but started with pts == 0 (e.g. for video with B-frames).

Michael NiedermayerandMartin Storsjö bd239c9a2e lavf: Don't drop both pts and dts if timestamps are invalid 
In these cases, only drop dts. Because if we drop both we have no
timestamps at all for some files.

This improves playback of HLS streams from GoPro cameras.
