bookmarks: pull --update updates to active bookmark if it moved (
issue4007)
This makes `hg pull --update` behave the same wrt the active bookmark as
`hg pull && hg update` does as of
2096e025a728. A helper function,
bookmarks.calculateupdate, is added to prevent code duplication between
postincoming and update.
