Please explain the sanity checking in the commit message already (which cases
are handled, and why are those invalid?)

Also this changes behaviour in rtpbin. We would now always have the 3s limit,
even if ntp-sync is enabled. Not when using rtspsrc as it works around that,
but when using only rtpbin.

+       stream_set_ts_offset (bin, ostream, ts_offset, bin->max_ts_offset,

Where do these 4ms come from? Maybe make them a #define at the top
