- roll in some patches from ubuntu via freebs:
- parse ~/.cups/lpoptions
- check whether the printer URI starts with http://,
ipp://, or smb:// to test whether its local or not
- do not warn on stderr in case of IPP_NOT_FOUND
- replace IPP_SET_PRINTER_ATTRIBUTES with CUPS_ADD_MODIFY_PRINTER
- fix a mem leak in gnome_cups_request_add_requested_attributes()
- fix PPD retrieval for printers picked up with cups browsing
(still broken, but these patches won't hurt anyway)
