af68c71a5e Add a -v and -N option to kenv(1), so it can be more easily used in
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.

87a99f5ff2 Various quibbles:
- 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.

ad3f90f6ca Deuglify the usage message by putting the program name after the
"usage:" string.  This is how most (all?) other programs in the system
do it.

c87a63c10f Initial kenv(1) hack for dumping the kernel environment. This can be
used to extract modified boot hints to make loader(8)-time changes
"sticky".  It tries to use \ style quoting so that it can be used directly
with foo.conf files.  It can also extract specific variables.
