hg: acquire wlock while updating the working directory via updatetotally...

hg: acquire wlock while updating the working directory via updatetotally updatetotally() might be invoked outside wlock scope (e.g. invocation via postincoming() at "hg unbundle" or "hg pull"). In such case, acquisition of wlock is needed for consistent view, because parallel "hg update" and/or "hg bookmarks" might change working directory status while executing updatetotally(). Strictly speaking, truly consistent updating should acquire also store lock, because active bookmark might be moved to another one outside wlock scope (e.g. pulling from other repository causes updating current active one). Acquisition of wlock in this patch ensures consistency in as same level as past "hg update".
