Use the revision just before libspeexdsp split

Using lowest PTS or DTS is a bad idea, as lower video packets are sent
ahead of pts, and most audio tracks are sending packets near to pts.
So we had audio packets coming late, with a lower pts, and corrupted
our PCR as we take the lowest pts among tracks.
We can't also guess the full tracks rolls, so updating after a full
roll instead of each packet is useless.
Send time is a reliable base time.

Offsets pts & duration

Reads keyframe flag from payload extensions.
Some formats like DVR-MS ships keyframe info into
payload extensions and not as packet flag. Why make things simple ?

already microseconds

Sub-Payloads must have their pts computed from deltapts.

Use pts as track time, and then for pcr.

It was unused since VLC started using automake, 11 years ago.
