The definition of ROOT::Reflex::longlong is now removed.

It is not needed by the Reflex API, and it interfers
with user code defining its own longlong, because
the dictionaries pull it in via "using namespace ROOT::Reflex".
Leave an "#if 0" in there, so it's easier to trace.

Only Kernel.cxx needs the typedef.
