create defs.mk for common definitions

# $FreeBSD$
Move all the ficl common code into ficl.mk There's a number of copies of basically identical code to enable building forth in /boot/loader. Move it all into ficl.mk.

Centralize several variables. MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the same, so set them in defs.mk. MAN= is common, so set it here too. This removes a lot of boring repetition from the Makefiles that added almost no value.

Fix build of userboot.so Since it's not possible to unset a variable easily, create a new variable 'PIC' to signal that we are creating a shared object that we want to install. defs.mk refains from defining NO_PIC and ITNERALLIB when PIC is defined. This unbreaks userboot.so building.

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. Pedro Souza's 2014 Summer of Code project. Rui Paulo, Pedro Arthur, Zakary Nafziger and Wojciech A. Koszek also contributed. Warner Losh reworked it extensively into its current form.

Instead, copy over the files we know are safe to use and constrain what else is used. We use -nostdinc to achieve this.

Install the 4th files in sys/boot/forth instead of each loader Also, move generation of loader.help into loader.mk. Set HELP_FILES= to disable this (so we only install one help file, for now). At the same time remove some duplicate -I lines. Fix several FILES= and CLEANFILES= into the += form since we're touching both of those in the .mk files. Make sure we only build one loader.help file per platform in a unified way (we were building many on some, with the last to install winning, though often they were the same text). Also, we're now installing loader.rc and menu.rc everywhere. arm and mips uboot installed these as menu.rc.sample, but there's no need since the loader.rc for those platforms doesn't do menu.rc processing by default. pcibios.4th is now installed everywhere, but will failsafe on non x86 platforms (it isn't loaded by default anywhere).
