HTTPS: fix python2.3, persistent connections, don't explode if SSL is not available
The urllib2 differences between python 2.3 and 2.4 are hidden by
using keepalive.py, which also gives us support for persistent
connections.
Support for HTTPS is enabled only if there's a HTTPSHandler class in
urllib2.
It's not possible to have separate classes as handlers for HTTP and
HTTPS: to support persistent HTTPS connections, we need a class that
inherits from both keepalive.HTTPHandler and urllib2.HTTPSHandler. If
we try to pass (an instance of) this class and (an instance of) the
httphandler class to urllib2.build_opener, this function ends up getting
confused, since both classes are subclasses of the HTTPHandler default
handler, and raises an exception.
