core: allow IPv4 to fail by default

Browse source 
(comments by dcbw)
This allows out-of-the-box connectivity	on IPv6-only networks.
Once caveat is that connections	where the user currently
expects	no IPv4	connectivity to	terminate the connection and
retry will no longer do	so until IPv6 also times out, and if
that network where IPv4	is expected to fail also has an IPv6
router sending advertisements, the connection will succeed
instead	of failing.  That can be resolved by setting the
right bit in the connection's config file; and it's expected
that the number	of users who expect IPv4 failure on a
network	with usable IPv6 connectivity is quite small
compared to the	benefit	of OOB IPv6 connectivity.
