The main purpose is to add commandline support for Transmitter Delay
Compensation (TDC) in iproute. Other issues found during the
development of this feature also get addressed.

This patch series contains four patches which respectively:

  1. Correct the bittiming ranges in the print_usage function and add
  the units to add clarity: some parameters are in milliseconds, some
  in nano seconds, some in time quantum and the newly TDC parameters
  introduced in this series would be in clock period.

  2. factorize the many print_*(PRINT_JSON, ...) and fprintf
  occurrences in a single print_*(PRINT_ANY, ...) call and fix the
  signedness while doing that.

  3. report the value of the bitrate prescalers (brp and dbrp).

  4. adds command line support for the TDC in iproute and goes together
  with below series in the kernel:
  https://lore.kernel.org/linux-can/20210814091750.73931-1-mailhol.vincent@wanadoo.fr/T/#t

I am sending this series as RFC because the related patch series on
the kernel side have yet to be approved. Aside of that, I consider
this series to be ready. If the can: netlink patch series get accepted,
I will resend this one as is (just remove the RFC tag).
