At the moment only APDUs are logged to GSMTAP. It is not uncommon that a
card is resetted by the UE multiple times during normal operation. When
the trace lacks the reset events (ATR) it becomes difficult to follow in
which state the card actually is. Let't mark reset events by sending the
ATR via GSMTAP (like simtrace2_sniff already does it)

osmo_apdu_segment_in() may return a negative number on receipt of
"unknown APDU case", and that would crash simtrace2-cardem-pcsc:
msgb(0x55d2cf7aa8a0): Not enough tailroom msgb_put
(allocated 920, head at 0, len 7, tailroom 1017 < want tailroom 65534)
backtrace() returned 19 addresses
Whenever osmo_apdu_segment_in() fails to recognize an APDU, the
communication is broken, because we don't know if we should continue
transmitting or receiving. Only a successful return value by would
allow us to know this. Do not crash, exit() gracefully.

Sometimes I get LIBUSB_TRANSFER_ERROR particularly when the USB bus
is very busy. We shouldn't terminate the program, but simply resubmit
it. That's what we have multiple transfers for...

We initialize a local variable to -1, and if the user specifies
no address from the command line, we use this in the interface match
struct, which uses a uint8_t. This means 255 ends up in there, and
as a result no usb interface ever matches unless the user explicitly
specifies the -A command line argument.
With this patch any absent -A argument will result in ifm.addr == 0,
which means "don't match on address", and which is what we want here.

In some readers (at least CardMan 3121), the simtrace2-cardem firmware
claims there are power-up sequences where RESET is released before VCC
becomes active. Let's detect such spec-incompliant power-up sequences
and use them to trigger a cold reset of the card.

There is no obvious reason why the st should be stuck in cardem mode
without a working running util on the host side since there is no state
that is being kept, so switch back to using the local sim upon reset.

This adds support for the new ngff_cardem board, a board that
basically combines a ngff breakout board with a built-in SIMtrace2.
Cardem works, but depending on the modem it might need a adjusted ATR to
ensure a lower baud rate is used by the modem, high rates might lead
to weird power cycling of the card after a few transfers.
Trace was also tested and appears to work as expected.

Before this patch, we would always use either a hard-coded default
ATR from the source code, or we would use one that the user specified
on the command line.
The more sane default is to pass-through the real ATR of the card.

This renaming is to avoid any confusion with the osmo-remsim
project, living in its separate git repository.
The simtrace2-cardem-pcsc doesn't feature any 'remote' part. Rather,
it emulates the SIM card interface towards the device/phone/modem,
and forwards it to a local PC/SC card reader.

The UDP based forwarding really only ever was a quick hack to
demonstrate the capabilities.
Meanwhile, we've had the proper osmo-remsim project implemented,
which provides a much more reliable and comprehensive way of
managing SIM card emulation devices (SIMtrace2, sysmoQMOD, ...)
and collection of card readers (sysmoOCTSIM or any other PC/SC
supported readers).
Hence, remove the "UDP forwarding part.
