* Fix a bug where the length of the ASCONF-ACK was calculated wrong due
to using an uninitialized variable.
* Fix a bug where a NULL pointer was dereferenced when interfaces
come and go at a high rate.
* Fix a bug where inps where not deregistered from iterators.
* Fix a race condition in freeing an association.
* Fix a refcount problem related to the iterator.
