[krbdev.mit.edu #1160] Kerberos requires non-loopback networking

[rbell@alumni.caltech.edu via RT]

	'Hi.  Unfortunately the Kerberos KDCs and servers require
non-loopback addresses to function properly.'
	'This constraint comes from the protocol specification not
from our implementation, so the code is correct as implemented.'
	If I comment out the two bits of code that causes Kerberos to
ignore the loopback interface it works fine for me.  I got all my
testing done at home and am ready to install it for the Committee.
	I wanted to know how IFF_LOOPBACK stays set no matter what I
do to unset it.  I don't see it set anywhere in the code.
