MINOR: lua-thread: Stop usage of struct hlua for the global lua state

The goal is to no longer use "struct hlua" with global main lua_state.

The usage of the "struct hlua" is no longer required. This patch replaces
this struct by another one.

Now, the usage of runtime Lua phase is separated from the start lua phase.
