Lua without IO

This is a customized version of Lua that does not do any IO.

You can toggle whether it's built with IO support in the luaconfig.h header, where you can undefine the LUA_NOIO flag.

Additionally, you'd need to change the src/Makefile to build lua and luac, as they use a lot of the Lua IO functionality.

src/noio is a test program that checks the no-IO setup.

Users of the no-IO version should probably implement these macros to provide output for their no-IO system, in lauxlib.h. They are noop by default.

/* print a string */
#if !defined(lua_writestring)
#define lua_writestring(s,l) {}
#endif

/* print a newline and flush the output */
#if !defined(lua_writeline)
#define lua_writeline() {}
#endif

/* print an error message */
#if !defined(lua_writestringerror)
#define lua_writestringerror(s,p) {}
#endif
