py3: use a BytesParser in notify extension

This is the first step to make the "long line" case in test-notify.t
pass by fixing a UnicodeDecodeError on Python 3.

We alias a parsebytes() in mail module, similarly as we already have a
parse() function for Python 2 and Python 3 compatibility.

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