Harald Welte d571a3e2e1 RSPRO: split ConfigClient into ConfigClientId and ConfigClientBank 
The point is that the ClientId is only set once at start-up (and
also only optionally), while the Bank IP/port/ID/slot can be changed
any number of times during a RSPRO connection.

Harald Welte 19f881a373 bankd: respond to IPA PING from client with IPA PONG 
The bankd worker threads handle the RSPRO connection from the
remsim-clients outside of our usual osmo* infrastructure and hence
they don't inherit the common IPA CCM handling.  This means we need
to explicitly implement the keep-alive PONG support.

What this doesn't add is any outbound keepalive handling towards
the client.

Harald Welte 2507597c42 bankd: Implement thread-safe SIGUSR1 talloc context reporting 
If the main thread receives SIGUSR1, we dump its talloc report and
then signal all worker threads so each can dump their own talloc
report.

Harald Welte 00a9673ac2 bankd: terminate bankd connection once map is deleted 
This implements a signal based mechanism by which the main thread can
inform worker threads that their mapping has just been removed and
they should hence terminate the connection and return themselves to the
pool.

Harald Welte 3cded63aa6 naming: Distinguish "rspro client" from "remsim client" 
"remsim-client" is the client program running next to a phone/modem
which is attaching to the SIM slot.

"RSPRO client" is a protocl-level client of the RSPRO protocol:
* the remsim-client connects as RSPRO client to the remsim-server
* the remsim-client connects as RSPRO client to the remsim-bankd
* the remsim-bankd connects as RSPRO client to the remsim-server

Let's clarify this in naming.

Harald Welte 707c85a49b Split "RSPRO client FSM" from "BANKD client FSM" 
This allows the RSPRO client FSM to be used by both remsim-client
as well as remsim-bankd -- both of which connect as RSPRO client to
remsim-server.

Harald Welte ec628e964e client: move ClientSlot from bankd_conn to srv_conn 
If the client uses a locally-configured (static) ClientId, then
the bankd_client_fsm.c code needs access to this information
at time of the connect to the server, not just when connecting
to the bankd.
