* codecs: walk open-GOP leading pictures back in a loop, not by recursion

MxfVideo::sync_before and MpegVideo::sync_before recursed one GOP back
per leading picture, so a crafted index whose every GOP leads its key
frame recursed once per GOP: tens of thousands of frames for a small
file, a plausible stack overflow in dev builds.

Both now use gop::open_gop_sync, a loop over the same steps. It stops
when the index's sync sample lies past the picture instead of looping,
and reads pts and keys with get().

Fixes #2803

* gop: keep decode_start's doc comment on decode_start
