loopback: Add new arguments to disable stream move

Browse source 
The arguments sink_dont_move and source_dont_move have been added to toggle
module automatic unloading when the sink or source were no longer
available, rather than just moving them to the next available
sink/source (via rescue streams).

Reviewed and tweaked by Colin Guthrie.
