Openfire considers that if a session has authenticated as A, and has
authenticated to B, then the session is already authorized to send stanzas
from A to B. This is not always the case.

This patch stores domain pairs (encapsulated as a DomainPair object) for a
session, and always authenticates if it has previously not requested
authorization for this domain pair.

This should be sufficient to fix OF-1309, but testing is tricky.

Fixing NullPointerException caused by having a mix of valid Groups and NULLs inside the result of getGroupsFromKeys

Openfire 4.2.0 will have the functionality that's now in the websocket plugin. As a result,
this plugin should not be used in Openfire 4.2.0. To facilitate this, we've defined a new concept
of 'priorToServerVersion' in OF-1353.

This commit defines that the plugin should only be used in Openfire instances prior to version 4.2.0.

websocket plugin has been broken since Openfire 4.1.4. This PR implements the missing code and fixes the issue

    @Override
   public ConnectionConfiguration getConfiguration()
   {
       // TODO Here we run into an issue with the ConnectionConfiguration introduced in Openfire 4:
       //      it is not extensible in the sense that unforeseen connection types can be added.
       //      For now, null is returned, as this object is likely to be unused (its lifecycle is
       //      not managed by a ConnectionListener instance).
       return null;
   }
