Add the lua scripts from the lua-bootloader SoC These are the .lua files from from Pedro Souza's 2014 Summer of Code project. Rui Paulo, Pedro Arthur and Wojciech A. Koszek also contributed. Obtained from: https://wiki.freebsd.org/SummerOfCode2014/LuaLoader Sponsored by: Google Summer of Code Improve the SoC lua menu code to bring it in line with forth menu functionality Submitted by: Zakary Nafziger Sponsored by: FreeBSD Foundation Use loader.setenv and loader.unsetenv instead of loader.perform Convert from include("/boot/foo.lua") to foo = require("foo"); to bring in line with latest lua module conventions. Enforce a uniform style for the new .lua files: o hard tab indenation for 8 spaces o don't have if foo then bar; else bas; end on one line MFC After: 1 month Relnotes: yes Differential Review: https://reviews.freebsd.org/D14295

lualoader: Add ability to intercept cli commands If we failed to execute the input line as pure lua, run the command through parse for consistent argument parsing. Pass the parsed arguments through to a global "cli_execute" written in Lua, which is expected to either handle it or pass it back through to interp_builtin_cmd (via loader.command). lua-handled cli commands will then exist as globals in whatever module they most belong in, and invocations at the loader prompt will magically dispatch to them if they exist.

lualoader: Address some 'luacheck' concerns luacheck pointed out an assortment of issues, ranging from non-standard globals being created as well as unused parameters, variables, and redundant assignments. Using '_' as a placeholder for values unused (whether it be parameters unused or return values unused, assuming multiple return values) feels clean and gets the point across, so I've adopted it. It also helps flag candidates for cleanup later in some of the lambdas I've created, giving me an easy way to re-evaluate later if we're still not using some of these features.

require("cli")
lualoader: Drop terminating semicolons This was previously chosen out of convenience, as we had a mixed style and needed to be consistent. I started learning Lua on Friday, so I switched everything over. It is not a very lua-nic convention, though, so drop it. Excessive parenthesizing around conditionals is next on the chopping block.

lualoader: Bring in local.lua module if it exists Provide a way for out-of-tree users of lualoader to patch into the loader system without having to modify our distributed scripts. Do note that we can't really offer any API compatibility guarantees at this time due to the evolving nature of lualoader right now. This still has some utility as local modules may add commands at the loader prompt without relying heavily on lualoader features- this specific functionality is less likely to change without more careful consideration.
