    kernel - Do not auto-destroy tap interfaces which are manually created
    
    * When a tap interface is created via 'ifconfig tapN create' it
      will no longer be automatically destroyed on the last close.
    
    * Previously could occur for tap units 4 or larger.
    
    * Fixes unexpected ripouts of manually created interfaces, which
      can be particularly bad when the interface is used in a PF rule.
