Yasushi SHOJI 7e35c7e1de canfdtest: Follow Bash exit status when signaled 
Bash and many other shells use 128 + signum as the exit status when a
program get signal and exit.  Follow the common behavior so that we
know how the programs are killed.

canfdtest.c was effectively raising the received signal again to run
the default signal handler.  This has been declined by the maintainer
because it's over-engineering.  This commit replaces it with the
method proposed by the maintainer.

Added the '-b' command line option, to be used in conjunction with the '-d'
option that enables CAN FD, to set the BRS bit in a CAN FD frame. When
enabled, the data part of the CAN FD frame is transmitted at a higher speed.
All remaining parts of the CAN FD frame use the classic CAN speed.

Oleksij RempelandOleksij Rempel ba603c59ae canfdtest: test if TX and RX msg are properly ordered 
In some cases we can get local TX echo after remote response
for same TXed message was already received.

For applications which relay on proper order of TXed and RXed
message this will be fatal.

With this patch the package generating side will test if TX and RX are
properly ordered.
Currently with following commands, this issue can be easily
reproducible:
canfdtest -g can0 &
while(true); do chrt 40 dd if=/dev/zero of=/dev/null count=10000; done
