[PATCH] lua: always return luaL_error in actions
Even if luaL_error is a "no return" function for the Lua runtime, adopt
also in action functions the "return" idiom recommeded for it.
This also helps code analyzers in not thinking that "g" might still be
null after the null check followed by luaL_error.

[PATCH 0/2] improve Lua API for files and initramfs objects
From: Paul Emmerich <p.emmerich at first-colo.net>
Hi,
the new API for initramfs and files in master lacked the ability to build
initramfs objects from files loaded via HTTP/TFTP in Lua. The documentation
indicated that it should be possible (and I believe I did that in an older
version). I implemented a few new functions to handle files/initramfs
objects better.

[PATCH 00/21] Upgrade to Lua 5.2.2, add filesystem module and get_key binding
Hi,
This series targets automatic boot menu generation, but most of it
is the Lua upgrade, because I got tired reading deprecated API docs.
It's mostly a straightforward forward port of the earlier Syslinux
specific changes to Lua 5.1, except that:
* I chose the add a stub getenv() implementation to the COM32 API
instead of #ifdefing out all the references in Lua, and
* I kept oslib
