Windows IPv6 cleanup - properly remove IPv6 routes and interface config

after tunnel shutdown.  Needs to make delete_route_ipv6() visible from
tun.c (route.c, route.h) and to properly zero-out host bits from IPv6
"network" at interface route clearing.  Further, add IPv6 routes with
"store=active" to make sure nothing lingers after a system crash while
OpenVPN was running.

While at it, small Solaris cleanup - use CLEAR() to zero-out "ifr" struct.

Tested on Windows XP SP3 and Win7 by Gert Doering and Tony Lim.
