D6355: shelve: add `update --shelve` if shelve extension is loaded

  Should this abort if subrepos are present, since you can't shelve a subrepo?  No -S is available on `update`, but maybe looking for .hgsub with any contents is good enough?
  
  I don't have time to play with it right now, but I know updating a dirty repo with dirty subrepos is massively confusing already.
