This patch adds `j1939-vehicle-position-srv`, a server for sending
vehicle position data over CAN using J1939 or NMEA 2000 protocols. It
retrieves GPS data from gpsd or simulates data if gpsd is unavailable.
By default, it operates in J1939 profile but can switch to NMEA 2000
with the `-p nmea2000` option.
Usage Examples:
1. With gpsd:
j1939acd -r 64-95 -c /tmp/1122334455667789.jacd 1122334455667789 vcan0 &
j1939-vehicle-position-srv -i vcan0 -n 0x1122334455667789
2. In simulation mode without gpsd:
j1939-vehicle-position-srv -i vcan0 -s -p nmea2000

Introduce the ISOBUS File Server (FS) interface, compatible with ISO
11783-13. The implementation utilizes the kernel's existing CAN J1939
socket support.
For testing following setup can be used:
ip link add type vcan
ip l s dev vcan0 up
j1939acd -r 64-95 -c /tmp/1122334455667788.jacd 1122334455667788 vcan0 &
j1939acd -r 96-127 -c /tmp/1122334455667789.jacd 1122334455667789 vcan0 &
sleep 1
isobusfs-srv -i vcan0 -n 1122334455667788 -v vol1:/path/to/export/
isobusfs-cli -i vcan0 -n 0x1122334455667789 -m 0x1122334455667788 -I

Systems that lack a MMU cannot use fork() to create the child process.
The patch does not compile the affected programs on MMU-less systems.

asc2nibble() is already defined in lib.h. Include lib.h in slcnpty.c
so that asc2nibble() does not need to be redefined a second time and
adjust the Makefile accordingly.

The PTX flavour canutils have a useful utility for generating a sequence of CAN
frames with an incrementing payload and checking such a sequence for missed and
reordered frames.
Recently, it has helped finding a regression in the kernel pfifo_fast qdisc,
which led to reordered frames.
To bring the utility to a greater audience, import the current state, including
its history, into the linux-can set of utilities.

Using j*smthng* for j1939-related tools is not very good for 2 reasons:
1. j prefix is not very informative;
2. jcat name is used by journal cat tool from popular sleuthkit toolkit;
2`. jacd sounds very similar to jackd.
2``. Possible future name conflicts for new tools.
Thus I renamed j* to j1939\1 to deal with this issue.
