[PATCH] removed unused macro "classname" , unused funcion "demangle_classname", unneccessary file "flower/rtti.cc"

[Bernard Hurley]

The definition of the function "demangle_classname" is the only content
of flower/rtti.cc. This is only referenced in
flower/include/virtual-methods.hh, where it is used in the definition of
the macro "classname".

Hence the references to "demangle_classname" in virtual-methods.hh can
be deleted along with the file rtti.c

Of course it is possible that someone may have added them recently with
a view to using them for something, but it looks like historical cruft
to me.

I append a pathch
