The interrupt counts may have been valuable in the past, but now DDB can
readily provide them via 'show intrcnt'. This is one of the only
consumers of these counter arrays outside of the interrupt code itself,

Along those lines, none of the callers seem to acknowledge that the

The patch introduced a behavior change coming from getopt_long, namely
the entire argument array would be parsed looking for opts, which
affected uses spawning new processes without passing '--' to delimit
where cpuset arguments end. [1]
Apart from that turns out the change had a bug: using CPU_LEVEL_ROOT
instead of CPU_LEVEL_WHICH, returning a different cpuset than intended.
[2]
The intended functionality is provided with nproc(1), which landed after
this change.
As such, revert for the time being.

The prior code mistakently thought that the g_consumer that hung off the
provider we found were the right thing to use to find all the glabel
aliases for this node. However, the only way to find that is to iterate
through all the geoms that belong to the glabel geom class, looking for
those geoms with the same name as the provider with the right efimedia.
Do this in a way that caches glabel class, and allows for it to be
absent. Tighten the filter for mounted filesystems to only look
for the ones that are mounted on /dev/.. since the rest of the code
assumes that.

In the past, we modified pcap/pcap.h to include the system net/bpf.h
rather than libpcap's own pcap/bpf.h. However, starting around 1.10.2,
libpcap requires a few extern functions defined in pcap/bpf.h to build.
Simply reverting that local change and pulling in pcap/bpf.h is not a
solution, because some ports with '#include <pcap.h>' such as mail/spamd
and net/xprobe require the system net/bpf.h to be pulled in. To
accommodate both requirements, make pcap/bpf.h a wrapper around the
system net/bpf.h, but retain the extern function definitions. This is
in preparation for libpcap 1.10.3.
