with a number of positive benefits:
- Start using UMA(9) statistics for mbufs and clusters, which avoids
using the mbuf allocator statistics which suffer from races under
load on SMP. This should eliminate "negative" mbuf counts in
netstat -mb.
- We are now able to track cached (free) mbufs and clusters and count
it towards memory allocated by the network stack.
- We are now also able to track memory allocated to mbuf tags since
libmemstat(3) can also query malloc(9). We don't print this except
as part of the total (for now - #if 0).
- We are now able to track mbuf/cluster/packet allocation failures,
although they are not currently printed (#if 0).
- Don't print out sfbuf statistics when running on a kernel core, as
currently that code is able only to query sysctl for statistics.

not change because it has been make's behaviour for ages.

The form of a pseudo target was deliberately choosen to minimize work
for POSIX compatibility (Makefiles are not allowed to use any targets
starting with a dot and consisting only of uppercase letters except those
specified in the standard when they want POSIX compatible behaviour, so
such a Makefile can never contain .EXPORTVAR.)

of asking the environment for each variable we could not find otherwise

NGROUPS groups. getgrouplist(3) may put a duplicate group
id into the passed array (it sets [0] and [1] to the value
of the gid argument), but id_print() sorts them out.
Showing the ids of both an user given by an argument to `id',
and the current user, is now handled in a single function.
Displaying the current user's ids was inaccurate because
getgroups(2) had been used. getgroups(2) returns the current
kernel state of a user's groups, which may not always be
correct if /etc/group was recently changed.
