web: provide diff summary to the changeset page

This is the same message displayed at the end of the "diff --stat" command.
For example, "9 files changed, 1651 insertions(+), 2 deletions(-)".

The webutil.diffstatgen function allows the diffstat data to be lazily
calculated only once and then re-used.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
