Major rework of the user-space event filtering

This patch reworks the user-space filtering. Although we have
kernel-space filtering since Linux kernel >= 2.6.26, we keep userspace
filtering to ensure backward compatibility. Moreover, this patch
prepares the implementation of the kernel-space filtering via
libnetfilter_conntrack's high-level berkeley socket filter API.
