Oleksij RempelandMarc Kleine-Budde 71b2aec834 j1939-vehicle-position-srv: Introduce J1939 and NMEA 2000 Vehicle Position Server 
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
