vnc: distiguish between ipv4/ipv6 omitted vs set to off
The VNC code for interpreting QemuOpts does not currently
distinguish between ipv4/ipv6 being omitted, and being
set to 'off', because historically the 'ipv4' and 'ipv6'
options were just flags which did not accept a value.
The upshot is that if someone runs
$QEMU -vnc localhost:1,ipv6=off
QEMU still uses PF_UNSPEC and thus may still bind to IPv6,
when it should use PF_INET.
This is another instance of the problem previously fixed
for chardevs in
