Rewrite in_control(), so that it is comprehendable without getting mad.

o Provide separate functions for SIOCAIFADDR and for SIOCDIFADDR, with
  clear code flow from beginning to the end. After that the rest of
  in_control() gets very small and clear.
o Provide sx(9) lock to protect against parallel ioctl() invocations.
o Reimplement logic from r201282, that tried to keep localhost route in
  table when multiple P2P interfaces with same local address are created
  and deleted.

I'm not sure what's going on. Perhaps it has to do with the last bit (about
keeping localhost route in table).

Maybe the problem goes away when updating freebsd-net-tools to 10.x...
