Revert "ISPN-4782 Drop the Mux Channel block in favour of a FORK protocol in the"

This reverts commit c150200b20018bbe9c2862764582b110abed6f59.
ISPN-4864 Drop the JGroups FORK protocol until we can properly support it
ISPN-4776 - The topology id for the merged cache topology is not always bigger than all the partition topology ids
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging
writes to log4j in the cdi module (and dependents).

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
