Subject: [PATCH] Use CUPS-1.6 IPP API getter/setter functions
CUPS 1.6 makes various structures private and introduces these ippGet
and ippSet functions for all of the fields in these structures.
http://www.cups.org/str.php?L3928
We define our own accessors when building against CUPS < 1.6.
Based on work by Jiri Popelka <jpopelka@redhat.com> at
