Make hg update more verbose by default (issue12)

(including small changes to revert and backout to not show these stats
 with the exception of backout --merge)

Show update stats (unless -q), e.g.:
K files updated, L files merged, M files removed, N files unresolved

Inform the user what to do after a merge:
(branch merge, don't forget to commit)

Inform the user what to do if a branch merge failed:
There are unresolved merges, you can redo the full merge using:
  hg update -C X
  hg merge Y

Inform the user what to do if a working directory merge failed:
There are unresolved merges with locally modified files.

     '''Iterate over files and the revs they changed in.
 
     Callers most commonly need to iterate backwards over the history
     it is interested in.  Doing so has awful (quadratic-looking)
     performance, so we use iterators in a "windowed" way.
 
     We walk a window of revisions in the desired order.  Within the
     window, we first walk forwards to gather data, then in the desired
     order (usually backwards) to display it.
 
     This function returns an (iterator, getchange, matchfn) tuple.  The
     getchange function returns the changelog entry for a numeric
     revision.  The iterator yields 3-tuples.  They will be of one of
     the following forms:
 
     "window", incrementing, lastrev: stepping through a window,
     positive if walking forwards through revs, last rev in the
     sequence iterated over - use to reset state for the current window
 
     "add", rev, fns: out-of-order traversal of the given file names
     fns, which changed during revision rev - use to gather data for
     possible display
 
     "iter", rev, None: in-order traversal of the revs earlier iterated
     over with "add" - use to display data'''
