   Now that pkgsrc-2011Q1 has arrived, and before -6 chimes in, change
   ifxname for xvif(4) from xvif%d.%d to xvif%d-%d. This is needed
   to avoid sysctl(9) EINVAL errors when creating interface nodes.

This change came awfully close to fixing PR misc/39376 too...

(Hyphens may be valid in sysctl nodes while dots are not, but neither
hyphens nor dots are valid in sh variables, for /etc/rc.d/network's
ifconfig_ifN.)
