Fixes: 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

The ASC file provides an information whether the CAN frame is sent (Tx)
or received (Rx) on the local CAN node.
With the new '-d' option the generation of this information is disabled
for the log file generation to simplify the comparision of log files.
E.g. log1 -> asc -> log2 always created the T/R information in the log2
file which is then hard to compare to the log1 file which might not
have the T/R information at all.

Since using the %n feature the tmp1 buffer is only used for the handling
of the CAN identifier. So this buffer can be shrinked for that use case.

The Remote Request Substitution bit is a dominant bit ("0") in the CAN XL
frame. As some CAN XL controllers support to access this bit a new
CANXL_RRS value has been defined for the canxl_frame.flags element.

TxRq messages are internal measurement messages that document the time of
a transmission request (to the CAN driver) to be checked against the real
transmission time, when the CAN message has been sent.
There is no such feature in the SocketCAN log format, so we detect this
tag but skip TxRq messages in the ASC log files.

Add '-s' option for display busload statistic, the output contains
minimal, maximum and exponentially-damped moving sums of one second
average (borrowed from Linux load average algorithm) since start or
reset (press 'r' while running).

With the introduction of CAN FD the bitrate has not been printed
correcty. Fix the CAN FD bitrate output and try to shrink the
bitrates by using kilo or Mega suffixes: 500000 -> 500k
