diffstat: properly count lines starting in '--' or '++' (issue5479)

Lines that start in '--' or '++' were previously not counted
as deletions or additions in diffstat, resulting in incorrect
addition/deletion counts.  The bug was present if the start
of the line, combined with the diff character resulted
in '---' or '+++'.

diffstatdata will now track, for each file, if it has moved
pas the header section by looking for a line beginning with
'@@'.  Once that has happened, lines beginning with '-'
or '+' will be counted for deletions and additions.  Once a
line beginning with 'diff' is found, the process starts over.

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