Some people need to avoid inclusion of GPL code for their use cases and thus
get easily spooked by GPL license headers. This code is actually licensed
under different licenses, only one of which is GPL, and it's already possible
to just upgrade from LGPL to GPL anyway so having the GPL listed explicitly
as one of the choices doesn't really add anything. So remove GPL from the list
and also add SPDX license identifiers while we're at it.

Ensure we take the object lock while accessing `GstElement.sinkpads`.
Use an iterator when the code isn't simple to avoid deadlock.
When we find the best pad, take a reference so a concurrent pad
release doesn't destroy the pad before we're done with it.

This adds two properties:
* scte-35-pid: If not 0, enables the SCTE-35 support for the current
program. This will write the proper PMT and send SCTE-35 NULL
commands (i.e. heartbeats) at a regular interval
* scte-35-null-interval: This specifies the interval at which the
NULL commands should be sent
Sending SCTE-35 commands is done by creating the appropriate SCTE-35
GstMpegtsSection and then sending them on the muxer. See the
associated example
Instead of using a static hardcoded PCR interval, allow the user
to configure it.
Also revert back the default to a 40 ms interval, that was changed
in recent patches for no good reason.
