the PMCs are system-wide, fine-grained and more tunable by the user.
We don't do application tracking, since it would require to store the PMC
values in mdproc and starting/stopping the counters on each context switch.
While this doesn't seem to be particularly difficult to achieve, I don't
think it is really interesting; and if someone really wants to measure
the performance of an application, they can simply schedctl it to a cpu
and look at the PMC results for this cpu.

iostat -y now reports data about waiting and active requests.
So far only drivers using dksubr and dk, ccd, wd and xbd collect data about
waiting requests.
This means that "mixerctl" (no args) will generate a usage msg, even when
/dev/mixer cannot be opened (or any other device given via -d or $MIXERDEVICE)
While here, get rid of "goto usage" replacing the usage: with a
static inline void __dead function... The compiler ought to optimise
the calls into essentially the same code as existed with the goto version,
but this is much cleaner.
Also, mixerctl falls back on /dev/mixer0 if /dev/mixer cannot be opened.
(that is old code - probably from when /dev/mixer was first added)
It used to do that when called as mixerctl -d /dev/mixer or with
"MIXERDEVICE=/dev/mixer mixerctl...". No longer. Now the fallback (which
is probably obsolete now anyway) only happens when the user doesn't specify
any mixer device (by either method) and the default of /dev/mixer is used.
In other cases, only the device specified is tried.
For unknown reasons, IPv6 multicast addresses are linked to a first
IPv6 address assigned to an interface. Due to the design, when removing
a first address having multicast addresses, we need to save them to
somewhere and later restore them once a new IPv6 address is activated.
mkludge stuffs support the operations.
This change links multicast addresses to an interface directly and
throws the kludge away.
Note that as usual some obsolete member variables remain for kvm(3)
users. And also sysctl net.inet6.multicast_kludge remains to avoid
breaking old ifmcstat.

netstat appends '*' to the name of an interface without IFF_UP, so
if_nametoindex which is used in mc_print fails. mc_print needs just
an interface index so pass it instead of a tweaked interface name.
The .SS field of the datetime argument of -t option can have range from 0 to 60

loop, to use signals properly. There are two copies of this code; one
uses kvm and the other uses sysctls. One copy had been updated to use
sigset_t and sigsuspend; the other was using vintage sigpause(). Sync
up the code so both use sigpause. Also, use sig_atomic_t, and block
SIGALRM when not waiting for it to avoid a small and unlikely but real

Since the non-modernized copy of the code *had* for some been
modernized to use setitimer instead of just alarm(), propagate that
change to the other copy.
These copies could share more logic than they do.

realpath(3) is expensive, and meta mode at least uses it extensively.
We use cached_realpath() to save the result of successful calls to
realpath(3) in a private variable context.
This improves the worst case performance (eg examining libc with
nothing to do) by a factor of 4.

Both meta_create() and meta_oodate() now share meta_needed()
to indicate if a .meta file is needed.
This allows for deciding that missing .meta file is cause of out-of-date.
The new knob 'missing-meta' controlls this, and is off by default
since the side effect files of generators like yacc will typically need
.NOMETA to avoid problems.
This however makes it much easier for folk to switch back and forth
with meta mode (eg. FreeBSD's normal build can leverage meta mode for
improved reliablility without need to clean).
Also if .MAKE.MODE does not contain 'nofilemon', the knob
'missing-filemon' allows control as to whether missing filemon data
should cause the target to be out-of-date.
Again off by default.
setting \n as the record delimited using a numeric value rather than literal
\n - and to not incorrectly turn \n into a field separator if -R is used to
make some other char the record separator (\n becomes a field separator in
that case as long as the field separator remains "white space" but should not
be in any other case - unless set explicitly of course.)
Plus more cosmetic changes - the man page and usage are updated to make it
more clear that the 2 (or 1) params to -k are not fields (field1 and field2)
but specifiers of the beginning and end of one key field. There was an
unused 'x' option in the GETOPTS string. The usage message is reformatted
to display properly on both 80 col and > 80 col displays (on < 80 it will
still probably look pretty ugly ... perhaps not quite so bad though), and
is also updated to show the different usage for the -c case (and -C) from the
others (only 1 file permitted) - the man page synopsis has a similar update.
Using more than one of -c -C or -m generates a usage message rather than
just ignoring the -m as it did before (there was no -C before of course).
Aside from the bug fix to the interaction between -R and -t, there are no
changes that affect the way anything is sorted (or read, or written).
