. Try harder to make sure the flags returned from getFlags isn't negative,

since a number of places in the code check for that and assume that it
  means an error occurred.  On FreeBSD, in particular, the value of
  ifr_flags can be negative if multicast is enabled on the socket since
  the possible flags have expanded to fill more than a short.

  Instead of blindly promoting ifr_flags to an int, which will preserve
  the sign, we fill the int return value with ifr_flagshigh in the high
  16 bits and ifr_flags in the low 16 bits.
