Special thanks to Deti Fiegl from the Leibniz Supercomputing Centre in Munich, Germany for providing the "fast" hardware to reproduce spurious bugs ;)

List of changes:
o Replace misleading flag NFCT_ANY_GROUP by NFCT_ALL_GROUPS
o Update test file to use NFCT_ALL_GROUPS
o Add missing check of CTA_PROTOINFO_TCP that resulted in a segfault in 
conjuction with events.
o Fix ICMP conntracks output
o Add missing prototype definition of nfct_default_expect_display_id in 
libnetfilter_conntrack.h
