Tobias Brunner 07df944c9c Add support to create IKE fragments 
All fragments currently use the same fragment ID (1) as that's what
other implementations are doing.

Tobias Brunner b816037739 Allow ID_PROT/AGGRESSIVE messages for established IKE_SAs if they contain fragments 
Other implementations send fragments always in an initial message type
even for transaction or quick mode exchanges.

Tobias Brunner 9b1659f52c Add message rules to properly handle IKE fragments 
These are sent in unencrypted messages and are the only payload
contained in such messages.

Tobias Brunner ddfad8b67e Reset the encrypted flag when handling IKE messages that contain a fragment 
Racoon sets the encrypted bit for messages containing a fragment, but these
messages are not really encrypted (the fragmented message is though).

Tobias Brunner 0080daa787 Fix deadlock in IMC/IMV managers 
Since reserve_id() might be called from e.g. notify_connection_change()
using a write lock will not work as this can't be acquired while holding
the read lock.

Also, with the previous code it was possible that two IMCs/IMVs added by
two threads at the same time would get the same ID assigned.
