  Log:
  Several fixes to ARP and route locking, that were done during 6.0 release
  cycle, and are also applicable to RELENG_5:
  
    o Make rt_check() return a locked rtentry.
    o Make rt_check() function more strict:
      - rt0 passed to rt_check() must not be NULL, assert this.
      - rt returned by rt_check() must be valid locked rtentry,
        if no error occured.
    o Modify callers, so that they never pass NULL rt0
      to rt_check().
    o Modify callers, so that they unlock rtentry.
  
    o Fix races in ARP code. See if_ether.c 1.139 for more information.
    o Fix LORs in ARP code. See if_ether.c 1.141 for more information.
  
    o Lock rtentry before dropping radix lock.
  
    o Send published ARP replies only on correct interface. [1]
  
    o Drop rtentry lock before calling rt_getifa(). [2]
  
    o Fixes to rt_setgate():
      - To avoid recursive rtentry locking.
      - Do not change routes in case of failure.
      - Return EADDRINUSE instead of bogus EDQUOT [3]
