mdiff: let _unidiff yield hunks as (<range information>, <hunk lines>)

Now _unidiff yields each hunk lines packed into a tuple with the "range
information" `(s1, l1, s2, l2)` that is used to build the typical hunk header
'@@ -s1,l1 +s2,l2 @@'.
This will be used to make it possible to filter diff hunks based on this range
information.

The new "range information" is ignored in unidiff() (only caller of _unidiff)
for now.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
