SVN rev 180968 on 2008-07-29 19:37:16Z by rwatson
When copying in and out current ICMPv6 filters on a raw IPv6 socket,
lock the inpcb and use a local stack variable to copy to/from userspace
so that sooptcopyin()/sooptcopyout() aren't called while holding an
rwlock.
While here, fix a bug in which a failed sooptcopyin() might lead to
partially consistent ICMPv6 filters on the socket by not ignoring the
error returned by sooptcopyin().
