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.

length to become 0, no data being send, and the reader reset the
card because of misbehaviour of the card (i.e. no/malformed
response leading to the timeout of the waiting time).

gcc isn't smart enough to see that:

Harald Welte 5a3613a57f bankd: Ignore IPA CCM and don't terminate if we receive it 
The IPA multiplex has a built-in sub-protocol called "CCM", which
we are not implemnting so far.  We still don't implement it, but
at least we don't terminate the TCP connection anymore if any such
unsupported IPA CCM is received.

make the version field a normal ASN.1 field.

In the PC/SC world, each slot is associated with a string name. In the
bankd for PC/SC readers, we need to establish a mapping which
bank_id/slot_nr maps to which given string name.  We use a minimalistic
CSV file for defining those mappings.  The file is read only once at
bankd startup time.
