If remsim-bankd connects via 127.0.0.1 or any other loopback-routed
IP address to the remsim-server, then the getpername() of remsim-server
for the bankd will also render 127.0.0.1, and subsequently that IP
address will be provided to remsim-client as address to connect to.
In almost all setups, remsim-client will be running on a remote node and
hence not able to reach remsim-bankd at 127.0.0.1.
Let's turn the server-IP into a mandatory command line argument of
remsim-bankd and not use a problematic default value.

So far the option only parsed the hexstring into the atr buffer, but
failed to update the length (from the default value of 2). Also set
atr.len so sending custom ATRs works.

- add new SRVC_ST_REESTABLISH_DELAY state with delay stipulated by table
k_reestablish_delay_s[], that implements a simple exponential-like back-off
with an upper bound.
- new function srvc_do_reestablish() is used to initiate a reestablish, and
apply the appropriate delay, if any.
- takes external delays (such as TCP connect() delay) into account, and does
not double-penalize.
- delay is reset to shortest possible if there has been no reestablish
initiated in a long time (2x greater than our longest delay). Allows for
fast reconnects even if a delay was used to connect.
- addresses issues https://osmocom.org/issues/5348 and https://osmocom.org/issues/5610

When the stderr of these services is sent to syslog, for example by
using systemd's StandardError=syslog, syslog's escaping of ANSI color
ESC sequences in log messages really clutter the log files. This
option allows log coloring to be disabled on the command line.

If a --gsmtap-host (-g) address is specified on the command line, trace
SIM ATRs and APDUs to the given IP. If --gsmtap-slot (-G) is provided,
limit tracing to the specified bank slot number. This feature may be
useful when diagnosing issues with the remote SIM framework.
Added new log category: DGSMTAP
Also, cleaned up alignment in bankd --help output and removed unused -o option.

Let's avoid a segfault and rather print a proper error message in case
we cannot find all the required USB endpoints when opening the
user-specified interface/config/device.
This can happen if the device is currently in DFU mode, or a completely
wrong device/interface was specified.
Before this patch:

- perform edge detection on RESET and VCC client indications to filter
out duplicate resets
- prior to this change, unrelated changes in the client slot status
indication (such as CLK change) could trigger duplicate resets
- these resets could happen in rapid succession and lead to reader
libusb communication errors that lock-up the PC/SC daemon
- a drop in VCC will always induce a cold reset, even if a warm
reset is already in progress.
- overall, this change better matches what the hardware would do

This introduces an --atr-ignore-rspro command line argument, which
will make the remsim-client ignore any RSPRO setAtrReq it receives
from the remote bankd.
The purpose of this is to modify the capabilities advertised by the card
towards the UE (modem/phone). For example, by modifying the ATR
one can disable/constrain the UE from using higher bit rate support, or
disable the use of logical channels.

Let's open the cards in EXCLUSIVE mode, we don't want other applications
tinkering with the card state while we have a bankd worker running on

we're dropping the current (new) connection as we don't really know which
is the "right" one. Dropping the new gives the old connection time to
timeout, or to continue to operate. If we were to drop the old
connection, this could interrupt a perfectly working connection and opens
some kind of DoS.
