Hardware timestamps have been introduced in Linux 2.6.30. Check for the
availability of SO_TIMESTAMPING and print an appropriate error message if
missing. Additionally fix some style issues and define the proper length
of ctrlmsg[].

GitHub user 'crossband' raised an issue regarding the strict-aliasing compiler
warning in his specific setup: https://github.com/linux-can/can-utils/issues/42
In fact memcpy() and memset() are a better solution than the former pointer
magics, so remove the issues and the compiler warning flag too.

Alan sent a pull request to update the README.md with some markdown tweaks
and a SocketCAN logo. Good idea!
After creating a SocketCAN logo PNG in the can-logos repository we can
reference the PNG inside the linux-can organization.
A license file needs to be added too - but this has to be discussed on the
mailing list first.

System startup needs to wait for tun device to be created before
continuing on use of the tun device. Add -D option to fork a daemon of
isotptun and exit(EXIT_SUCCESS) when the tun device can be used.
Log errors to syslog when daemonized or to stderr when in foreground.

and usage goes to stderr.
Change to print errors to stderr.

Exit code does not tell if the service was provided or if it was not
provided due to command line or setup errors.
Change errors to return EXIT_FAILURE instead of 0. Also change other uses
of 0 to EXIT_SUCCESS and 1 to EXIT_FAILURE for clarity and POSIX
conformance.

The sscanf() function to parse bcmserver command strings limited the length of
the CAN netdevice name to six characters. With this patch the length is derived
from the IFNAMSIZ which defines the space in ifr.ifr_name.

With glibc versions before 2.17, we get following build error:
canfdtest.o: In function `millisleep':
canfdtest.c:(.text+0x212): undefined reference to `clock_nanosleep'
collect2: error: ld returned 1 exit status
make[1]: *** [canfdtest] Error 1
make[1]: *** Waiting for unfinished jobs....
glibc versions before 2.17 needs to link with -lrt for
clock_nanosleep(). This patch adds support to detect if linking with
librt is required.
This build issue is detected by Buildroot autobuilder:

After a few complaint about 100% CPU usage of canfdtest over our PCI
-like boards, I have had a look to the source file, and think I have
found the issue in can_echo_dut().

This patch fixes a bug in cangen.c
Bug: When used with -m option, if a CAN FD frame with BRS option set is
sent, that flag never gets cleared for the subsequent frames.
Fix: Reset frame.flags at the start of iteration.
