Fix Comet with HTTP/APR connector

Fix Comet with HTTP/APR connector
r1144391 switched the key for the processor map for this connector from the socket to the socket wrapper. That prevented Comet from being able to retrieve the processor from the map when processing a comet event.
This commit changes all the connectors to map the socket (or rather whatever the SocketWrapper wraps) to the processor rather than the SocketWrapper.
