Harald Welte fb48de8968 server: Log connection establishment from bankd/client; warn on localhost
If a bankd connects to the server from 127.0.0.0/8, then clients will
not be able to reach it unless they also run on localhost.  Warn the
user.

Harald Welte a9d7ad1175 switch to libosmocore multihread-logging
When osmo-remsim was originally developed, libosmocore logging was
not yet thread-safe.  This meant that the worker threads of remsim-bankd
and remsim-server could not log via the libosmocore logging framework
but directly used stderr/stdout, which produced rather inconsistent log
output.

However, since 1.3.0, libosmocore has received support for
multi-threaded applications.  Let's make use of this and consistently
use it in remsim-server and remsim-bankd.  This obviously also means
adding some more log categories.

Harald Welte 3598c58eb8 server: Send ConfigClientBankReq with bankd_port == 0 on map delete
If a slotmap is deleted via the REST API, don't only remove it from
the bankd, but also remove it from the client.

Harald Welte 6b990f914f rspro_server.c: Fix memory leak in processing inbound RSPRO
We need to unconditionally free the msgb that gets handed into
sock_read_cb() by the ipa server.

Harald Welte 1c691b173a rspro_server: Give proper name to IPA_KEEPALIVE FSMs
Once we know the Client / Bankd Identity, update not only the connection
FSM with that identity, but also the IPA keepalive FSM.  This will
provide proper context when logging.

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.
