    Add some missing newin{}.
    
    * docs/reference/Doxyfile.in: Add ALIASES newin.
    * sigc++/functors/macros/functor_trait.h.m4: Add newin{2,2,11} to
    SIGC_FUNCTORS_DEDUCE_RESULT_TYPE_WITH_DECLTYPE.
    * sigc++/signal_base.h: Add newin{2,4} to signal_impl::blocked(), block() and
    signal_base::blocked(), block(), unblock(). Bug #153780.
