Bump PKGREVISION to 1.

Fix build on NetBSD/sparc64 3.x: sync CPP symbols usage between
struct addrinfo definition and its usage in getaddrinfo().

While here define struct addrinfo's pad members the same way as in
NetBSD's /usr/include/netbsd.h and sync code in
lib/bind/irs/getaddrinfo.c:getaddrinfo().

This had been reported to bind9-bugs at isc dot org.
