As discussed with Adam on discord current Lite XL Lua Plugin API was not
working on native plugins with more than 1 source file since imported
symbols were not exposed to other unit files. The issue was tackled on #1332
but the solution introduced another issue when Lite XL was dynamically
linked to the system lua. So we opted to tackle this by using function
wrappers around the function pointers.
* Reintroduce some missing Lua API's from native plugin API
* Add new upvalue functions to header
* Fix things that are actually macros in current lua
* Introduce lua_insert,replace,remove macros from lua5.4
* Getting ready for 2.1.
* Fixed version.
* Year.
* Manually added line as takase said to.
* Fixed minor issue at takase's behest.
* Dunno where that went.
* Updated to use a function pointer.
* OK, as discussed, adding this manually for now.
* Updated SDL.
