When a test process is not able to write to TH_LOG_STREAM, this step
mechanism enable to print the assert number which triggered the failure.
This can be enabled by setting _metadata->no_print to true at the
beginning of the test sequence.

Update the seccomp-bpf test to return 0 if a test succeeded.

This feature is needed for the Landlock tests.

Changes since the patch from the Landlock series:
* add the step counter in assert/expect macros and use _metadata to
  enable the counter (suggested by Kees Cook)
* only count asserts
* add documentation

I am looking through my Inbox and found this one. Okay to pull
this in for 4.14-rc1?

Yes, could you please pull this one instead of the one from my Landlock
patch series [1] (which is already in your tree)? This patch is more
up-to-date and include documentation.

Thanks,
