port mod_ipp to Apache 2.2
We have an Apache module for IPP printing, here:
It currently requires Apache 1.x headers to build.
We'd like to build it against Apache 2.2 (the one illumos currently uses).
The module compiled that way will probably work on later Apache too.
It was also suggested we should not install the Apache plugin module in a directory that assumes any particular version of Apache might be installed. Dealt with that by changing the delivery locations to:
etc/lp/ipp/httpd-standalone-ipp.conf usr/lib/lp/ipp/mod_ipp.so var/lp/ipp-listener/index.html
