Approach: Keep filling the receive buffer until we have found enough data to extract the first HTTP header and body

Add a second timeout to differenciate keepalive and ping alive packets. We now wait 55s before sending a keepalive (whitespace packet) and 2 minutes before sendind a xmpp ping (and then we wait for 1min the answer before reconnecting) Fixes #4643

Introduce a get_instance factory method for all plugins and other xmpp related classes. This will help us to decouple plugs in order to make them testable.

Proposed Fix. Make sure we read all data from our SSL socket wrappers and don't just rely on gobject.io_add_watch, select or poll.

This isn't really a clean solution, but the less intrusives fix that I can think of. Fixes #2634.
