The sim presence pin allows the simtrace2 to inform the modem
about the presence of the simcard. On a generic simcard slot a
button is pressed by the simcard which generate a high or low voltage level.
Even though there are specifications of minipcie or ngff defining this signal, certain
modems behave different.
Certain modems require different signals from the specification.
Extend the usb protocol to set the behaviour at runtime.

Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

the device ID (unique to the micro-controller) is now displayed in
the USB iSerial descriptor.
the git version is now also displayed in iConfiguration in an
additional (empty) configuration descriptor.
this allows the user to quickly get the device hardware serial and
firmware version just by using lsusb (no need for a custom USB
software).

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.

We now generalize the USB communiction and abandon the 'req_ctx'
structure inherited from openpcd. Instead we use the libosmocore 'msgb'
structure to handle incoming and outgoing USB tranfers. We also use
linuxlist-based msgb-queues for each endpoint.
