fix bad assumption about uniqueness of file versions
Mercurial had assumed that a given file hash could show up in only one
changeset, and thus that the mapping from file revision to changeset
was 1-to-1. But if two people perform the same edit with the same
parents, we can get an identical hash in different changesets.
So we've got to loosen up our uniqueness checks in addgroup and in
verify.
