testing: Reorganizing IKEv1 and IKEv2 examples

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.

+An IPsec <b>transport-mode</b> connection between the natted host <b>alice</b> and gateway <b>sun</b>
+is successfully set up. <b>leftfirewall=yes</b> automatically inserts iptables-based firewall
+rules that let pass the decrypted IP packets. In order to test the host-to-host connection
+<b>alice</b> pings <b>sun</b>.<br/>
+<b>Note:</b> This scenario also demonstrates two problems with transport-mode and NAT traversal:
+<ol>
+<li>The client <b>venus</b> behind the same NAT as client <b>alice</b> is not able to ping <b>sun</b>
+(even with ICMP explicitly allowed there) because the request arrives unencrypted and thus gets
+dropped when the IPsec policies are consulted (increases the <em>XfrmInTmplMismatch</em> counter
+in <em>/proc/net/xfrm_stat</em>).</li>
+<li>A similar issue arises when <b>venus</b> also establishes an IPsec <b>transport-mode</b> connection to
+<b>sun</b>. Due to the conflicting IPsec policies <b>sun</b> will use the newer SA from
+<b>venus</b> to send traffic to the common transport mode address.</li>
