Lane userdata implementation refactoring:

    - Refactor lane proxy implementation: it is now a full userdata instead
      of a table, and its methods are implemented in C instead of Lua.
      * its metatable is no longer accessible.
      * writing to the proxy raises an error.
      * it is no longer possible to overwrite its join() and cancel() methods
    - when a deep userdata idfunc requests a module to be required, manually
      check that it is not loaded before requiring it instead of relying on
      the require function's loop detection feature.
    - when a module must be required, raise an error if the 'require' function
      is not found in the target state.
    - we know Lanes is loaded in the master state, so we don't force it
      to be required in every lane too when a linda deep userdata is copied.
