* video: refactor PTS code, add fall back heuristic to DTSwm42013-11-271-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the PTS handling code to make it cleaner, and to separate the bits that use PTS sorting. Add a heuristic to fall back to DTS if the PTS us non-monotonic. This code is based on what FFmpeg/Libav use for ffplay/avplay and also best_effort_timestamp (which is only in FFmpeg). Basically, this 1. just uses the DTS if PTS is unset, and 2. ignores PTS entirely if PTS is non- monotonic, but DTS is sorted. The code is pretty much the same as in Libav [1]. I'm not sure if all of it is really needed, or if it does more than what the paragraph above mentions. But maybe it's fine to cargo-cult this. This heuristic fixes playback of mpeg4 in ogm, which returns packets with PTS==DTS, even though the PTS timestamps should follow codec reordering. This is probably a libavformat demuxer bug, but good luck trying to fix it. The way vd_lavc.c returns the frame PTS and DTS to dec_video.c is a bit inelegant, but maybe better than trying to mess the PTS back into the decoder callback again.

* demux: export dts from demux_lavf, use it for aviwm42013-11-251-2/+23
| | | | | | | | | Having the DTS directly can be useful for restoring PTS values. The avi file format doesn't actually store PTS values, just DTS. An older hack explicitly exported the DTS as PTS (ignoring the [I assume] genpts generated non-sense PTS), which is not necessary anymore due to this change.

core is used in many unix systems for core dumps. For that reason some tools work under the assumption that the file is indeed a core dump (for example autoconf does this). This commit just renames the files. The following one will change all the includes to fix compilation. This is done this way because git has a easier time tracing file changes if there is a pure rename commit.
