D6776: bookmarks: validate changes on push

[durin42 (Augie Fackler)]

  Clarifying I understand: this causes pushing a bookmark to fail in what cases that it currently succeeds? I think it's just the case of:
  
    o 2
    |  o 1 @
    o/ 0
  
  when I last pulled, `@` was on 0, and now I'm doing `hg push -B @`, but since my last pull the server advanced `@` to 2, meaning it's a non-linear update. Right?
  
  If so, I wholeheartedly approve, as this behavior has previously burned me and I think it's well past time we started breaking some compatibility edges on bookmarks to make them actually useful to share.
