queue: add requeue, fix unqueue_matching

Synchronized with emane.git's implementation of this code which
includes a unit test.

This commit also fixes two bugs in unqueue_matching and one inb
unqueue:

- unqueue_matching was returning the wrong pointer when
  there was no match

- both unqueue_matching and unqueue were not clearing the vacated
  queue entry after removing the item
