version 3.4.4
   * bugfix: take into account the fact that "coroutine" is no longer part of base library in Lua 5.2
   * bugfix: if "bit32" was listed in the libraries, it wouldn't open (library list parsing failing on digits)
   * bugfix: Use luaL_requiref() to open standard libraries in Lua 5.2 as we should
   * bugfix: any Lua state created by Lanes reuses the allocator function of the originating state
   * bugfix: don't call on_state_create() while GC is suspended during lua state initialization
