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)
Closes: #4414

This is useful if we have external programs interfacing with
stdin/stdout of osmo-remsim-client-shell. We don't want that output
to hang in some buffer indefinitely, but rather have the lines flushed
immediately.

We may want to develop programs that include multiple instances of
a remsim_client. Let's remove the global variable 'g_client' and
instead de-reference the bankd_client using container_of() macros

This is a remsim-client with an interactive 'shell', where the user
can type in C-APDUs in hex formats, which will be sent to the bankd /
SIM-card. Responses received from SIM Card via bankd will be printed
in return.
