The early environment is typically cleared, so these new options
need the PRESERVE_EARLY_KENV kernel config(8) option. These environments
are reported as missing by kenv(1) if the option is not present in the
running kernel.

The contents of the kenv will be dumped to stdout, while dump could have
also meant 'discard'. Call it 'list' instead.

Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate
package, which requires pre-install/post-install scripts, to be
added later.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

scripts the way sysctl(8) is. The -N option, like in sysctl(8),
displays only the kenv names, not their values. The -v option prints an
individual kenv variable name with its value as name="value". This is
the inverse of sysctl(8)'s -n flag, since the default behaviour of
kenv(1) is already like sysctl(8) -n.

- Print a diagnostic if kdumpenv() fails. This can occur due to MAC
restrictions or lack of memory. Catch all kenv(2) failures as well.
- Just of the heck of it, DTRT if the kernel environment size changes
at the wrong time. The old code could fail silently or fail to
null-terminate a buffer if you got exceptionally unlucky.
- Sort and GC the #includes.

"sticky". It tries to use \ style quoting so that it can be used directly
with foo.conf files. It can also extract specific variables.
