CC/CXX/CPP/LD may all have arguments supplied in various circumstances,

tools we're expecting to invoke from PATH, which just requires
examination of the first word. Limit our scope to exactly that.

kbdcontrol: Support building as a bootstrap tool on old and non-FreeBSD

Systems that predate 971bac5ace7a ("kbd: consolidate kb interfaces
(phase one)") cannot build kbdcontrol since kbdelays and kbrates moved
to sys/kbio.h. Moreover, on non-FreeBSD, it requires all kinds of ioctls
and sysctls that are highly FreeBSD-specific to build, but we use it as
a bootstrap tool to generate the keymaps used by some kernels (LINT ones
in particular). Thus, when bootstrapping kbdcontrol, disable everything
that's not needed for that singular use, and use the in-tree kbio.h to
get the definitions of the necessary structures.

This allows KBDMUX_DFLT_KEYMAP, UKBD_DFLT_KEYMAP and ATKBD_DFLT_KEYMAP
to be enabled when building on non-FreeBSD, and thus LINT kernels.

tools/build: Work around broken Clang FreeBSD resource dir logic pre-13

Prior to Clang 13 (e.g. in the Clang 11 present in 13.0-RELEASE), the
resource directory logic for FreeBSD was broken and would not resolve
symlinks, meaning symlinks would only work if in a directory next to the
containing lib directory. Therefore we cannot even use a symlink for
worldtmp, we have to make a wrapper script that execs the real binary
via an absolute path.

namespace nv names, version libnv and libnvpair library symbols

libnv and libnvpair have aliased symbols, and as a result a single process which
dlopens a shared object that is dynamically linked to libnv and another to
libnvpair will wind up with a single set of resolved symbols for those in
conflict. A source file also cannot include both libnv and libnvpair headers
because of aliased identifiers. To resolve the situation, libnv types and
functions are namespaced via nv_namespace.h, and libnv symbols are
versioned. The msgio functions are not namespaced or exported as they are not
part of the external API.

The imported ctf.h is modified to depend only on _types.h, and also to

in a parent CTF container.
