Tobias Brunner f1aa18b2e8 ikev2: Send retransmits using the latest known addresses 
For instance, if a DPD exchange is initiated by the gateway when a
mobile client is roaming and it then gets a new IP address and sends
an address update via MOBIKE, the DPD retransmits would still be sent
to the old address and the SA would eventually get closed.

Tobias Brunner b678d9e14f ikev2: Send and receive fragmented IKE messages 
If a fragmented message is retransmitted only the first packet is passed
to the alert() hook.

Tobias Brunner 7a53fe5511 ike: Do not cache MID of IKEv2 fragments 
This fails if there are unencrypted payloads before an encrypted
fragment payload in the first fragment.

Tobias Brunner 40bab9a176 ike: Move fragmentation to ike_sa_t 
The message() hook on bus_t is now called exactly once before (plain) and
once after fragmenting (!plain), not twice for the complete message and again
for each individual fragment, as was the case in earlier iterations.

For inbound messages the hook is called once for each fragment (!plain)
and twice for the reassembled message.

Tobias Brunner 249aa67f87 ipsec: Only set PATH if it is not already set 
The comment indicated this but it was always set anyway.  All internal
commands are called via their absolute paths, so the script only uses PATH for
the uname command, but if that is not located in one of the configured
directories the script will fail.

Also, since the internal commands are called via their absolute paths there is
no need to add the directories to PATH.

Tobias Brunner d52b8738b5 ikev1: Fix handling of UNITY_LOAD_BALANCE 
The re-authentication is now handled within the original IKE_SA if it has not
yet been established, so we don't want to destroy it.

Tobias Brunner d4828f51e0 ikev1: Don't queue more than one mode config or XAuth task 
At the time we reset an IKE_SA (e.g. when re-authenticating a not yet
established SA due to a roaming event) such tasks might already be queued
by one of the phase 1 tasks.  If the SA is initiated again another task will
get queued by the phase 1 task.  This results in e.g. multiple mode config
requests, which most gateways will have problems with.
