libosmo-simtrace2 traditionally had only supported blocking, synchronous
I/O, while remsim-client used asynchronous USB I/O. Using async USB I/O
for IRQ + IN transfers while using blocking I/O for OUT transfers
doesn't seem to work reliably, so we have to switch OUT also to async.

This way we have consistent logging from all parts of the code via
the common libosmocore logging infrastructure.

The remsim_client code already used FSMs for the connections
to both remsim-server and remsim-bankd. However the 'main' part of the
program was not yet implemented as a FSM, making it somewhat difficult
to perform the right actions in every possible situation.
This commit re-structures the code around a central main_fsm, which
gets notified from the per-connection FSMs and which handles the common
processing. It also handles the execution of external script commands,
and hence further unifies the code base between the different backends
(simtrace2, ifd_handler, shell)
