Moving the libstdc++ lists

[Benjamin Kosnik]

Definitely keep the libstdc++ and libstdc++-cvs lists. I don't care about 
the other one (libstdc++-prs, because the bug database is its own thing 
anyway.)

Note that the java group has pretty much requested the same kind of 
infrastructure. I don't think this is especially hard to implement, and 
it will make the developers in question much happier.

thanks,
