Collecting cvsps patches

Since there are has been some work done here and there on cvsps, but upstream does not seem to have time to issue a new release, I have started to collect the patches I found.

I guess this is a good place for a heads-up: if you know of any other bugfixes or feature patches to cvsps, I'd like to hear about it, so I can add it to my repo.

Not that the master branch is an octopus merge of all works in there, including my preliminary work on multiple-tag support, so for now you may want to do your own mix.

For now it has:

* bugfixes and such:

Anand Kumria:
      FreeBSD isn't evil - just misguided

Linus Torvalds:
      Increase log-length limit to 64kB
      Improve handling of file collisions in the same patchset
      Fix branch ancestor calculation

Yann Dirson:
      Cleanup the tag handling to simplify multi-tag handling
      Dependency handling

* features

Yann Dirson:
      Allow to have multiple tags on a single patchset.
