mssdemux: add connection-speed property
...
This speed limits the maximum bitrate of streams. Currently it
is only read when starting the pipeline, but it should be used
for switching bitrates during playback to adapt to network
changes.

mssdemux: add an 'active' flag to manifest stream
...
mssdemux should set the streams it has exposed as active so that
the manifest won't use the non-active streams to compute total bitrates
or providing fragments

If no streams are known, signal an error about no playable streams to
the application

with the downstream qtdemux so that it forwards the seeks and
the corresponding newsegments

mssdemux: add timescale to the caps

or at the top-level manifest entry
