Direct CVS import tool

I've got some rather large, broken, CVS trees that I'm trying to migrate
to git (X.org).

Attempts to do this with the existing cvsps-based git-cvsimport have
proved rather disasterous; missing files, incorrect log messages and
incorrect revisions are spread throughout the tree, including on the tip
of each branch.

I'm reasonably sure the problems are caused by cvsps, and while I've
hacked at that quite a bit, it seems like it's so focused on analysing
the tree for putative software engineering reesarch that it cannot be
made to accurately reproduce the tree via changeset analysis.

So, I've given up hacking cvsps and wrote a simple RCS file parser that
directly reads ,v files into a git-like revlist structure, and then
merges those together into a final tree. At this point, it's generating
the right head information for every named branch, but it's still not
successfully connecting all of the branches back together at suitable
points.

It's also not yet generating actual git trees; instead it dumps the
generated revision tree structure to a graphviz file for visual
inspection of the results.

But, I figured instead of doing this work in secret, I'd let people know
what I'm up to in case others want to play along.

And, of course ideas for a suitable name would be welcome.
