devel: add a config field to force dates to timestamp 0

Add a new config field named default-date under the devel section to force all
implicits date to a specific value. If a explicit date is passed, it will
override the default.

This patch only affect changesets. Other usages (blackbox, obsmarkers) are
updated in later patchs.

The test runner is setting a bunch of alias to force the '--date' argument. We
will replace theses aliases in a later patch.

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