- Normalize the preemption/ipi setting code by introducing sched_shouldpreempt()
so the logical is identical and not repeated between tdq_notify() and
sched_setpreempt().
- In tdq_notify() don't set NEEDRESCHED as we may not actually own the thread lock
this could have caused us to lose td_flags settings.
- Garbage collect some tunables that are no longer relevant.
Quoth the man-page:
Fifologs provide a compact round-robin circular storage for recording
text and binary information to permanent storage in a bounded and pre-
dictable fashion, time and space wise.

the NOPs used are 0x01.
While we could simply pad with EOLs (which are 0x00), rather use an
explicit 0x00 constant there to not confuse poeple with 'EOL padding'.

- Allow realpath to accept multiple paths on the command line.
- Add -q to suppress warnings if some paths can't be processed, and use
getopt(3) to process flags.
- Print the path being requested rather than a possibly partially
processed path when a failure occurs so that you can tell which of
several passed paths did fail.

- Add -v to print file names as they are processed; -vv prints the flags
change as well.
- Add -f to ignore failures with the same semantics as chflags(1), neither
printing an error nor affecting the return code.
- Don't try to set the flags if they won't change.
I made minor cosmetic tweaks to the code in the patch.

- rev. 1.11: Use PRId64 instead of a cast to long long and %lld to print
an int64_t.

HPT drivers would sometimes test the value of a preprocessor definition but
not always make sure that the definition existed in the first place, leading
to warnings on newer compilers. I blindly assumed the same with this driver,

The change as committed differs slightly from the patch in the PR,
as I force the size of the retrieved value (and the automatic
address increment) to be sizeof(void *). This seems to provide
the most useful auto-increment behavior, and defaults using the
default size (4), which is not sizeof(void *) on 64-bit platforms.
