Merge hashlib-2763-3
Author: wsanchez, exarkun
Reviewer: exarkun, mwhudson
Fixes: #2763
Replace uses of md5 and sha modules in Twisted with use of a new twisted.python.hashlib
module which transparently uses the new hashlib standard library module if it is available
or falls back to md5 and sha if not.
