[rdiff-backup-users] Restarting development

[Josh Nisly]

Development on rdiff-backup has stagnated for the last while. I think that this is attributable to several reasons:
* Andrew has dropped of the face of the earth, (he's working on graduate studies, IIRC) and I've been busy with other things. Since we're the two core maintainers, that tends to slow things down.
* I started work on unicode support, but realized that it requires a transition period. In current CVS, it's broken just enough to make life difficult.
* The code isn't structured all that well. This is at least partially because we don't have good automated tests, so it's hard to refactor without breaking things.
* We're still using CVS :-)

I propose that we, at least for now, pull the Unicode changes out of CVS. This is unfortunate for a number of reasons, but hopefully we can bring back in transition code that will make full support possible. Additionally, we need to develop a comprehensive test suite that runs on all supported platforms. Code changes should be accompanied by tests.

Once the unicode changes are pulled back out, I've a fair number of patches sitting in my own queue that can go in.

Feedback is welcome,
