lua: reduce diffs between luaconf.h copies

Upstream luaconf.h is contrib/lua/src/luaconf.h.dist, while userland lua
and loader lua have copies in lib/liblua/luaconf.h and
stand/liblua/luaconf.h.

Adjust whitespace, VCS tags, etc. to match upstream's version, for ease
of comparison.

We need to define the LUA_FLOAT_INT64 macro even if we don't use it (copied
from stand/luaconf.h). While touching luaconf.h.dist also sync it with the
the 5.3.5 release version (matches the one in lib/liblua).

flua: don't allow dlopen, et al., for bootstrap flua

There are some logistics issues that need to be sorted out here before we
can actually allow this to work.

flua: support "require" for binary objects in the base system

Export symbols from flua, and enable dlopen.

flua: initial support for "require" in the base system

Use /usr not /usr/local for base system components.

Use /usr/lib/flua and /usr/share/flua (not lua) for consistency and to
avoid the possibility that other software accidentally finds our base
system modules.

Also drop the version from the path, as flua represents an unspecified
lua version that corresponds to the FreeBSD version it comes with.

LUA_USE_DLOPEN is not yet enabled because some additional changes are
needed wrt symbol visibility.

liblua: ensure that "require" will fail in bootstrap flua

We do not want to support bootstrapping lua modules, so ensure that
require will fail by providing a nonexistent path.

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.
