blackhole(4), except that blackhole(4) uses sysctl's. This xref

- introduce a -o option that displays opaque variables.
- introduce a -x option that displays opaque variables in full.
- deprecate -A in favor of -ao and -X in favor of -ax.
- remove -A and -X from usage() and SYNOPSIS (but not from DESCRIPTION).
- ignore -a if one or more variables were listed on the command line.
- deprecate -w, it is not needed to determine the user's intentions.
- some language and style cleanup in the man page.
This commit should not break any existing scripts.

This will make a number of things easier in the future, as well as (finally!)

by sysctl and never can be in their documented form (kern.name_max would
have to become fs.filesystemname.name_max, etc.).

seem to misnamed. <sys/sysconf.h> says that they correspond to POSIX2
names, but the sysconf names don't have POSIX2 or "posix2" like all the
other POSIX2 names.
via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)
Now it is at least possible to prohibit one user opening maxfiles
