9189cdcb1d flvdemux: Don't write an empty string as a tag 
To stop warnings like:

a3933ea53d flvmux: Fix invalid padlist accesses. 
Request pads can released at any time, so make sure to hold
the object lock when iterating the element sinkpads list where
that's safe, or to use other safe pad iteration patterns in
other places.

When choosing a best pad, return a reference to the pad to make sure it
stays alive for output in the aggregator srcpad task.

Should fix a spurious valgrind error in the CI flvmux tests and some
other potential problems if the request sink pads are released while
the element is running..

e836640bd5 flvmux: Support rollover in timestamp 
For live streams, if we keep the stream for a long time, the timestamp
will be larger than max_uint32. In that case, timestamp should be handled
as a rollover timestamp rather than a backward timestamp.

7cbc351e05 flvdemux: Don't replace video codec data when we receive a PAR 
Receiving a pixel-aspect-ratio should trigger a caps change, but not
replace the existing video codec tag

flvmux: Correct metadata handling in file and stream mode 
In file mode, only push one onMetaData at the start of the stream.

In stream mode, always push complete onMetaData. They get replaced, not
merged.

c28a9d5d9c flvmux: Add encoder metadata to the header 
And also add a property for setting this. By default it has the same
value as the metadatacreator metadata.

Various software is using encoder instead of metadatacreator, others are
using them both for different purposes. As such it's useful to have
support for setting both here.

this case, the codec_data variable is the size of the header for
the CODEC part of Video Tag. The remaining is supposed to be the
H.264 codec data, hence should not be empty.
