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).

Add '-P' option for allow user to set the socket priority. This can be
useful in conjuction with queuing discipline.

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

Rework to use a single CAN socket for the received CAN traffic.
This allows to shutdown and restart various CAN interfaces without
terminating the application.
Additionally an auto detection has been implemented with the 'any' CAN
interface. E.g. with any@500000,2000000 CAN interfaces that have not
been defined before are assigned with the given 'any' bitrates when a
CAN frame from this CAN interface has been received.

The CAN interface description can now have two bitrates.
Extend the length check to handle the CAN FD data bitrate correctly.
