[syslinux] [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 for its exit() and getenv() functions.
   
I kept the various changes needed to make Lua compile in separate
commits to simplify future forward porting, but this breaks the
Syslinux build until the 12th patch in the series.  Shall I disable
Lua until then, or is this breakage a manageable inconvenience during
bisection?  Also, the current extension modules are disabled during
this series, but reenable at the end (with a slight change in usage:
they must be explicitly require()d before use).

The Lua 5.2.2 tarball does not contain tests, so that directory is
gone now.  They were not of much use in my opinion.

Maybe the extension modules should be moved into another directory,
I'm not sure.

And an official stat() implementation would be very useful.  After
inventing mine, I noticed rosh also invented its own...  Given some
instructions about which underlying interface it should be based on,
I'd give a shot implementing it.

Comments welcome.

Ferenc W?gner (21):
  lua: import Lua 5.2.2
  lua: replace src/Makefile to build Lua as a Syslinux COM32 module
  dev.h: get size_t definition
  lua: the COM32 API does not provide signal.h
  lua: explicitly put the console in standard mode
  lua: the COM32 API does not provide locale.h
  lua: use integer arithmetic
  lua: the COM32 API does not provide strcoll()
  lua: the COM32 API supports only part of iolib
  stdlib.h: provide a stub definition for getenv()
  lua: the COM32 API actually supports exit() of oslib
  lua: the COM32 API does not support time()
  lua: the COM32 API does not support freopen()
  sys/module.h: remove the #ifdef DYNAMIC_MODULE condition
  sys/module.h: fix some typos in function documentations
  lua: enable dynamic module loading
  lua: add the LuaFileSystem library
  lua: reactivate the syslinux extension module
  lua: bind get_key() in the syslinux module
  lua: also reactivate the cpu, dhcp, dmi, pci and vesa extension
    modules
  lua: make the dmi module standalone

[syslinux] [PATCH 02/21] lua: replace src/Makefile to build Lua as a Syslinux COM32 module

Start with the src/Makefile in Syslinux before importing Lua 5.2.2.
Refresh the core Lua object list based on the original Makefile.
Add the new builtin library objects.
Temporarily remove the Syslinux extension library objects, as they
need adjustments for the new API.

Under Lua 5.2 modules are not expected to set global variables
to reduce namespace pollution. Explicit require() is preferred.

Hmm, yes.  The series is available at https://github.com/wferi/syslinux
as well (lua52 branch, based on upstream firmware branch).
