Add --[enable|disable]-v4-mapped configure option to control
whether or not Apache expects to handle IPv4 connections
on IPv6 listening sockets. Either setting will work on
systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
must be used on systems that always allow IPv4 connections on
IPv6 listening sockets.
Note: As the ssl config file is not automatically generated and
it is expected to require editing anyway to work, the only
change there was to suggest the required Listen statements
in a comment.
