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.

flua: add fbsd module This module is bundled into flua, it only provides for now the exec function.

flua: add ucl library libucl comes with a Lua library binding. Build it into flua. This lets us parse/generate config files in the various formats supported by libucl with flua. For example, the following script will detect the format of an object written to stdin as one of UCL config, JSON, or YAML and write it to stdout as pretty-printed JSON: local ucl = require('ucl') local parser = ucl.parser() parser:parse_string(io.read('*a')) local obj = parser:get_object() print(ucl.to_format(obj, 'json')) Reviewed by: kevans, pstef Approved by: mmacy (mentor) Relnotes: yes Differential Revision: https://reviews.freebsd.org/D25009
