mpegtslivesrc: Fix mismatch between internal / external time usage
...
Previously the internal time was stored as base offset for calculating
the external time from the PCR, which resulted in disconts being
detected wrongly.

mpegtslivesrc: Rename variables to make it clear which time domain they refer to
...
We have the internal time domain (monotonic clock) and the external time
domain (scaled monotonic clock in the rate of the PCR).

mpegtslivesrc: Parse PAT/PMT and only handle PCRs from the first program
...
This matches default behaviour of tsdemux and makes sure we're not
jumping between different PCRs if there are multiple.
At a later time, program selection could be implemented.

mpegtslivesrc: Check if old compared to new PCR clock estimation is too far off
...
It the difference between the two estimations is more than 1s then
consider this a discontinuity too.

The first one should be the internal time, i.e. the monotonic clock time
in our case, and the second one the external time.

More work is needed to make this work seemlessly and right now it would

mpegtslivesrc: Don't skip the first MPEG-TS packet
...
If every buffer contains only a single MPEG-TS packet we would otherwise
skip over everything and would never observe a PCR.

net: New mpegtslive element
...
This element allows wrapping an existing live "mpeg-ts source" (udpsrc,
srtsrc,...) and providing a clock based on the actual PCR of the stream.
Combined with `tsdemux ignore-pcr=True` downstream of it, this allows playing
back the content at the same rate as the (remote) provider **and** not modify
the original timestamps.
