While we print failure messages on the console, sometimes logs are lost or
overwhelmed. Keeping a count of how many times we've failed retriable commands
helps get a magnitude of the problem.
Retried commands can indicate a performance degredation of an nvme drive. Keep
track of the number of retries and report it out via sysctl, just like number of
commands an interrupts.
We don't split the other man pages in their own package so do the same for runtime.

This reworks my last commit in r301285 to more closely match what was in
r241298 (but reverted in r294878).
This is addressing "missing .meta file" rebuilds but also ensuring that
files are always generated when needed in each case.
Note that this is not a complete rework of the problem areas identified
in r301285 as most are "good enough" right now as the new pattern
is too verbose. It's only worth making this current change where headers
may be generated in the INCS list; where missing .meta file rebuilds are
spotted.
--- Technical details follow ---
Several attempts to deal with this problem of multi-output targets, with and
without META MODE, were explained in r241298, r294878, and r301285.
The general problem is with multi-output targets such as:
foo.c foo.h:
touch foo.c foo.h
foo.c foo.h:
touch foo.c
touch foo.h
foo.c foo.h: foo.in
./generator ${.ALLSRC}
This pattern is problematic in jobs mode as both files end up being
built concurrently and leads to races. With META MODE it is worse
as both targets end up rebuilding if they lack a .meta file. So the
generator is force built twice even though it is only needed once.
There are also problems in that 'make foo.h' may be ran before 'make foo.c';
The order of make generating the targets is not guaranteed.
An older attempted workaround to this (discussed in r294878) was:
foo.h: foo.c
foo.c: foo.in
./generator ${.ALLSRC}
This appears fine except that if foo.h is missing and foo.c exists then
foo.h will never be regenerated. This pattern is close to the solution
in this commit though:
foo.h: foo.c .NOMETA
.if !exists(foo.h)
foo.c: .PHONY .META
.endif
foo.c: foo.in
./generator ${.ALLSRC}
There's 2 differences here:
1. foo.h will never expect to have a .meta file since the foo.c target
will generate both and own the .meta file.
2. If foo.h does not exist then it needs to force foo.c to be rebuilt
with .PHONY. That normally disables META MODE though so .META is
given to tell bmake we do really expect a .meta file.
This pattern cannot work with implicit suffix rules since the .c and .h files
may be generated at different times (buildincludes vs depend/all).

The nvme drive dumps only the most relevant details about a command when it
fails. However, there are times this is not sufficient (such as debugging weird
issues for a new drive with a vendor). Setting hw.nvme.verbose_cmd_dump=1
in loader.conf will enable more complete debugging information about each
command that fails.

It is declared here and in rfc931.c and unused here so keep that copy
and discard this one.
