[bitbake-devel] RFC: hg fetcher improvements

[Dan McGregor]

I've made some more changes to the Mercurial fetcher. I'd like
feedback on my changes; they're not that minor. I've made it
always fetch the full repo, and share the repo with the checkouts
in WORKDIR, just like the git fetcher.

The most important change, I think, is that it generates a Mercurial
bundle of the repository for the mirrors. Do people thing that's a good
idea, or should I switch it to creating a tarball of the hg repository
like git does?
