In the SIMtrace and QMOD schematics the LEDs are connected to +3.3V.
Thus to switch the LED on we need to set the pin low.

the waiting time (WT) is used to detect timeouts (e.g. for
unresponsive card or just to signal an error/NAK). it is essential
to detect to timeout to end current data transfer (e.g. change state).
by default (after a reset) to timeout is 9600 ETU, but this can change
at two places:
- after the ATR using the value of TC2 (if present)
- after a PPS (only F is used, and not D)
because the timeout value can be larger than the 16-bit of the USART
TO register, an external variable needs to be used for the count down.

Handling the USB message queue is done in an ISR and take quite some time.
This can cause a USART/SIM sniffing buffer overrun, resulting in data loss.
By setting the USB IRQ lower than the USART IRQ, the USB ISR can be
interrupted (for short) and no data gets lost.

don't wait for space to be available in the buffer since since would
prevent from processing non-console (e.g. debug) more important data

Use USART 0 connected to the SIM card side to sniff the communication.
The card side can also measure ETU times.
Do proper pin initialization.
This code can already capture the ATR communication between phone and card.

because the applications share the board capabilities defined in
libboard/*/include/board.h and USB configurations are enabled according
to the previously defined capabilities in libcommon/source.usb.c, all
applications actually offer the same functions.
thus creating the trace application is only mainly a cosmetic change, as the
sniffer function will also be present and enabled in the cardem application.

In commit eac1bec428 we start to use the
ringbuffer inside the console printing code. As a result, we must not
use TRACE_*() or printf() from within ringbuffer.c code to avoid
infinite recursion.
Instead, let rbuf_write() return a negative return value in case the
ring buffer overflows. This way, the callers (outside the
console/stdout code) can print an error message themselves.

This is required to make python pexpect.fdexpect happy, as it
requires that all characters are echo-ed back in order to detect
when the output of a given command starts.

the curent local copies of libosmocore headers + source is a temporary
hack anyway. We should instead rely on a system-wide install of
libosmocore cross-compiled for arm-none-eabi. But leave that as a
second (later) step beyond this patch.
