EFI secure boot VECTX related changes

When VECTX is enabled as a kernel option and non-EFI loaders are

LOADER_VERIEXEC_VECTX or not in readin.h. Source that includes
bootstrap.h must ensure the kernel option agrees with the compile
time CFLAGS in the various make related files.

stand: liblua: add a pager module

This is nearly a 1:1 mapping of the pager API from libsa. The only real
difference is that pager.output() will accept any number of arguments and
coerce all of them to strings for output using luaL_tolstring (i.e. the
__tostring metamethod will be used).

The only consumer planned at this time is the upcoming "show-module-options"
implementation.

Add flua to the base system, install to /usr/libexec

FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.

flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.

linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.

luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.

src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

stand: consolidate knowledge of lua path

Multiple places coordinate to 'know' where lua scripts are installed. Knock
this down to being formally defined (and overridable) in exactly one spot,
defs.mk, and spread the knowledge to loaders and liblua alike. A future
commit will expose this to lua as loader.lua_path, so it can build absolute
paths to lua scripts as needed.

Add Lua as a scripting langauge to /boot/loader

liblua glues the lua run time into the boot loader. It implements all
the runtime routines that lua expects. In addition, it has a few
standard 'C' headers that nueter various aspects of the LUA build that
are too specific to lua to be in libsa. Many refinements from the
original code to improve implementation and the number of included lua
libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default
module path. Numerous cleanups from the original GSoC project,
including hacking libsa to allow lua to be built with only one change
outside luaconf.h.

Add the final bit of lua glue to bring in liblua and plug into the
multiple interpreter framework, previously committed.

Add LOADER_LUA option, currently off by default.

Presently, this is an experimental option. One must opt-in to using
this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been
lightly tested, so keep a backup copy of your old loader handy.
The menu code, coming in the next commit, hasn't been exhaustively
tested. A LUA boot loader is 60k larger than a FORTH one, which is
80k larger than a no-interpreter one. Subtle changes in size
may tip things past some subtle limit (the binary is ~430k now
when built with LUA). A future version may offer coexistance.

Bump FreeBSD version to 1200058 to mark the milestone.
