patch to apache for IPv6 only httpd

[Curtis Villamizar]

FYI-

This very simple patch prevents an assert when httpd is run on a
server that has no IPv4 address.  An example is a BSD jail running
with only an IPv6 address on the interface (no loopback so no
127.0.0.1 address to bind to).

Copy the patch below into the files directory as
/usr/ports/www/apache22/files/patch-server__config.c

The port maintainer is on the Cc.  No bug has been reported.

BTW- I noticed this a long time ago.  I don't remember if I reported
it or forgot to.  Appologies if this is a duplicate.  It is not in the
httpd-2.2.22.tar.bz2 tarball, in the distinfo dated 23 July 2012.
