025b4a2f8d splitmuxsrc: Convert part reader to a bin with a non-async bus
A pipeline always has an async bus, which involves allocating an fd pair. As
splitmuxsrc only uses the bus' sync handler, this is not required and can easily
cause splitmuxsrc to exceed the fd limit for no good reason.

The other features of GstPipeline are also not needed here, e.g. clock selection.

c1a1584dde splitmuxsrc: Don't create part reader elements initially
Only create the part reader elements internally the first time
the part is activated. Saves some startup time when preloading
a large number of fragments

64fd2b265f splitmuxsrc: Add num-lookahead property
Add a `num-lookahead` property that will 'prepare' a number of
fragments in advance of the playhead if they have been deactivated
or closed by a limited number of `num-open-fragments`. It can help
to avoid any play stalls reading the indexes or headers of the next
file from high-latency media or on resource limited machines.

93c04e7473 splitmuxsrc: Rename some internal terminology
A part reader can be 'loaded' (prepared, but not currently outputting anything)
or 'playing' (actively being used to output data)

1294264ab9 splitmuxsrc: Keep streams aligned during adjustments
When calculating the timestamp offset to apply to
media streams in a fragment, ensure that all fragments
are offset "together" to preserve alignment in cases
where there might gaps in a recording at a fragment boundary.

682db96a41 splitmuxsrc: Add add-fragment signal and examples
Add a signal that allows adding fragments with a specific offset
and duration directly to splitmuxsrc's list. By providing the
fragment's offset on the playback timeline and duration directly,
splitmuxsrc doesn't need to measure the fragment making for faster
startup times.

Add a bus message that's published when fragments are measured,
reporting the offset and duration, so they can be cached by an
application and used on future invocations.

Add examples for handling the bus message and using the 'add-fragment'
signal.

1821b52dd5 splitmuxsrc: Add num-open-fragments property
Add a property to limit the number of parts splitmux will open
simultaneously. Modify the part handling to support deactivating
and reactivating the demuxing for each part.

The default is '0', to preserve the existing behaviour of opening
all parts at the beginning.
