onwards to git

[Jim Meyering]

I've converted the trunk and all branches, filtering
to aggregate commits, and cleaning up by removing empty commits
and applying heuristics to use reasonable commit messages
derived from ChangeLog entries.

The result is uploading to the glibc1.git repo:

    http://sources.redhat.com/git/gitweb.cgi?p=glibc1.git;a=summary

All existing tags have been adjusted to point to the
rewritten commits, too.

If this turns out to be good enough, I'll rename it to glibc.git
in the next day or two.

Feedback welcome,

Jim
