src: allow to use nfct handler for conntrack and expectations at the same time
This patch re-works the callback handling to allow the use the same socket to send/receive commands and listen to events of both conntrack and expectation subsystems. Now you can register one callback for conntrack and one for expectation with the same handler with no problems (before this patch, this was not possible, you required two different handlers).
