Oliver Hartkopp 99c5c14790 can.h: canxl: support Remote Request Substitution bit access 
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.

Oliver Hartkopp cb5ab07f34 asc2log: handle and skip TxRq messages 
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.

Oliver Hartkopp 7665e1e236 canbusload: add auto detection of CAN interfaces 
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.
