testing: Reorganizing IKEv1 and IKEv2 examples

Browse Source 
For documentation purposes the new folders ikev1-algs, ikev2-algs,
ikev1-multi-ca and ikev2-multi-ca have been created. Most of the
test cases have now been converted to the vici interface. The
remaining legacy stroke scenarios yet to be converted have been put
into the ikev2-stroke-bye folder.

For documentation purposes some legacy stroke scenarios will be kept
in the ikev1-stroke, ikev2-stroke and ipv6-stroke folders.

The roadwarriors <b>alice</b> and <b>venus</b> sitting behind the router <b>moon</b> set up
tunnels to gateway <b>sun</b>. Since both roadwarriors possess the same 10.1.0.0/25 subnet,
gateway <b>sun</b> uses Source NAT after ESP decryption to map these subnets to PH_IP_CAROL10
and PH_IP_DAVE10, respectively.
<p/>
In order to differentiate between the tunnels to <b>alice</b> and <b>venus</b>, respectively,
<b>XFRM marks</b> are defined for both the inbound and outbound IPsec SAs and policies using
the <b>mark_in</b> and <b>mark_out</b> parameters in ipsec.conf.
<p/>
<b>iptables -t mangle</b> rules are then used in the PREROUTING chain to mark the traffic to
and from <b>alice</b> and <b>venus</b>, respectively.
<p/>
The script designated by <b>leftupdown=/etc/mark_updown</b> automatically inserts
iptables mangle rules that mark the inbound ESP packets as well as iptables IPsec-policy rules
that let pass the tunneled traffic. In order to test the tunnel, the hosts <b>alice</b>
and <b>venus</b> ping the client <b>bob</b> behind the gateway <b>sun</b>.
