f48aac560c sniffing: decrease USB IRQ prioprity to prevent USART overrun 
Change-Id: I870a0aa8e251bbb53249c54bfcaa45de5b5a9486

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.

7ddf46ce1c sniff: use USART 0 instead of USART 1 
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.

9d90d284ed Use system include <foo.h> notation for libosmocore headers 
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.

3b646955b9 Fix swapped manufacturer/product strings 
the */usb_strings.txt files always assumed that the first line is the
manufacturer string, followed by the product string in the second line.

However, the enum strDescNum had it the other way around. Let's fix it
by adjusting the enum to reality.

23c00b6ad3 cardemu: Fix interpretation of MSGC_MODEM messages 
msg->l2h should always point at the first byte of the header after the
generic simtrace header.  For some reason this doesn't work if used
globally, but it is required for the MSGC_MODEM messages to be
interpreted correctly.

25a9a80ff5 Convert to new generalized SIMTRACE2 USB protocol 
The current protocol was card-emulation specific.  The new protocol is
generic/flexible enough to accommodate both tracing and card emulation,
as well as modem control and other future extensions.

8e7fca3255 migrate from req_ctx to msgb 
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.

that has a proper maintained embedded build (again).
