I think that any libstdc++ lists that are kept should move to @gcc.gnu.org

For libstdc++-prs, one difficulty is that we are likely to get C++ problem
results where it is initially not clear if the bug is in the compiler or
the library.  It might be cleaner just to have one combined set of prs.

For cvs, having a separate list to track checkins might make it easier
for developers who only care about libstdc++ to spare themselves unwanted
traffic.

That suggests keeping libstdc++ and libstdc++-cvs, but combining the
others (except maybe patches?).

I think that we should treat bugs as one lump. We can use GNATS categories
to separate things out.  As for patches, whatever is most convenient to
the main developers.
