I think lua_Stack is more appropriate than lua_Thread;

Consider code
- In C having L1 as reference
- it calls Lua code
- The Lua code calls another C function, having L2 as reference

If you name it lua_Thread, you would assume L1 and L2 would be the same, as they run on the same coroutine/thread. But they are not the same, they both have their own stack to interact with Lua.

Hence lua_Stack would be more appropriate I think.
