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.
