recentchangesdiff: truncate extremely large diffs

A diff was already truncated after 200 lines. But it could still be
arbitrarily enormous, if a spammer or other random noise source likes long
lines. That could use a lot of memory to html encode etc the diff and fill
it into the template. Truncating after 100kb seems sufficient; it allows
for 200 lines of up to 512 characters each.
