I'll need for the upcoming cthelper infrastructure. Moreover, we avoid
more fragmentation in the netfilter user-space utilities. And the plan
is that `nfct' will replace `conntrack' at some point.

else, piping "conntrack -E expect" output will be buffered/delayed,
which is not what users expect. Normal conntrack events are already
flushed.

This patch adds missing information regarding several conntrackd
options to the manpage and the help info that is displayed in the
command line.

You have to use this:
iptables -I PREROUTING -t raw -j CT --ctevents assured,destroy
instead of:
iptables -I PREROUTING -t raw -j CT --ctevents assured
Otherwise, conntrackd cache gets full since no destroy events
are delivered.

This patch uses the new infrastructure that allows us to filter
by mark from kernel-space.
This change ensures backward compatibility with kernels with
no support for filtering by mark (Linux kernel <= 3.4.x).
This requires lastest libnetfilter_conntrack library.

I forgot to modify the body of msg2exp to include the recently
committed support for the expectation class, helper name and NAT.
This patch fixes the problem.
Now in node-1 (primary), it shows:
proto=17 src=192.168.11.4 dst=192.168.10.5 sport=0 dport=5060 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.10.5 master-dst=192.168.11.4 sport=5060 dport=5060 PERMANENT class=0 helper=sip [active since 31s]
And it node-2 (secondary), it shows:
proto=17 src=192.168.11.4 dst=192.168.10.5 sport=0 dport=5060 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.10.5 master-dst=192.168.11.4 sport=5060 dport=5060 PERMANENT class=0 helper=sip [active since 180s]
This has been tested with the SIP conntrack helper.

This patch allows you to dump the internal and external expectation
cache in XML.

Now you can dump expectations in XML format and display the timestamp.
conntrack -L exp -o xml,timestamp

If ExpectationSync On is used, we synchronize no expectations at
all due to a problem in the event filtering.
This is bug, this patch fixes the problem.
