onwards to git

Please name all the existing branches and all the existing tags 'cvs/*',
and as a top-level name only leave 'master' as a copy of the final
'cvs/master' id (which will stand as the marker of when CVS was cut off).
(Leave no tags at all not under 'cvs/'.)  For all the branch and tag names
to be used in the future, we'll make them manually with new naming
conventions.


Thanks,
Roland
