12f6b80429 Added purge_tree for connection_t's which are no longer in the connection,
active or id trees, but which may still be referenced. This tree is flushed
when it is safe, this replaces purge_connection_tree().

Also lots of bugfixes related to the new trees.

319e0cb48e Split connection list into two lists:
- one list to handle all incoming/outgoing TCP connections
 - another list to handle all UDP connections

This will prevent race conditions.
