* Merge from debian unstable. Remaining changes: - pbuilderrc, debian/pbuilder.config, debian/pbuilder.templates: Set default archive mirror to "archive.ubuntu.com/ubuntu". - pbuilderrc: Set default distribution to "natty" and the default keyring to the Ubuntu one. - pbuilderrc: change how we pass keyring in DEBOOTSTRAPOPTS - debian/rules: install temporary locale so man page tests don't cause FTBFS.
