Converts usage of Avahi API to DBus calls. This change allows
us to remove dependency on avahi-gobject and avoids of possible
circular dependency.
Lists printers if Gtk+ is compiled with CUPS 1.6 or newer.
Show printers advertised by avahi on local network. CUPS
backend now looks for _ipps._tcp and _ipp._tcp services
offered by avahi. If it finds such a service (printer)
it requests its attributes through IPP_GET_PRINTER_ATTRIBUTES
ipp request and adds it to the list of printers. Such printer
behaves like a remote printer then.
If an avahi printer is a default printer then it is considered
default by the backend only if there is no local or remote
default printer.
This functionality is enabled when building Gtk+ with CUPS 1.6
or later because it replaces browsing protocol removed in CUPS 1.6.

If the PPD is not available when the printer is loaded then the PPD options are
not available and we can't get the correct qualifier to use with colord.
When the PPD becomes available, refresh the profile title to reflect reality.

This functionality adds a new 'Printer Profile' entry to the 'Color' page in the
UNIX print dialog if colord support is enabled.
This shows the user what color profile will be used for the settings they have
selected, and if no profile or the default profile is going to be used.
We are deliberately not allowing the user to _change_ the selected profile, as
the ICC profile is an implementation detail, and we should not change the other
print settings based on the characterization state.
The OpenICC group broadly recommend showing the profile that is used, so that
power users can be sure the correct profile is being used at the right time.
Normal users won't care, as they don't know how horrible the color match is
without profiling the printer and media.
Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)
and G_IMPLEMENT_INTERFACE use automatic variables for GTypeInfo and
GInterfaceInfo structs, while tutorials and source code often use
static variables. This commit consistently adopts the former method.

Check for 'auth-info-required' attribute from printer attributes to
find out whether an authentization of user is needed.
Change password dialog of print backend to be able to require informations
requested thru 'auth-info-required' (#566522).
This patch tests availability of remote host before getting ppd file
for selected printer (#586207). It also adds a state message for
failure of getting details.

* modules/printbackends/cups/gtkprintercups.[ch]
(gtk_printer_cups_get_ppd_name): change return value and local
variable to const gchar* to fix warning about discarding const
qualifier.
svn path=/trunk/; revision=20021
* modules/printbackends/cups/gtkprintbackendcups.c:
(cups_request_printer_list_cb): Get the name of the first printer
in a class to use when requesting a PPD
(cups_request_ppd_cb, cups_request_ppd): Fix the parameters of
the "details-acquired" signal emittion
(cups_request_ppd): get the ppd name from the cups printer
* modules/printbackends/cups/gtkprintercups.c (gtk_printer_cups_get_ppd_name):
New method for getting the name of the ppd we should request
2006-05-04 Alexander Larsson <alexl@redhat.com>
* gtk/gtk.symbols:
Added new symbols
* gtk/gtkpagesetupunixdialog.c:
* gtk/gtkprintunixdialog.c:
Destroy backends when finalizing dialogs.
Fix printer leak in selected_printer_changed.
* gtk/gtkprintbackend.[ch]:
Convert from interface to baseclass.
Move printer hashtable here so that the baseclass can handle
the slightly complicated ownership model.
Add gtk_print_backend_destroy which runs the dispose method,
causing the ref-cycles between the backend and its printers
to be broken.
Add gtk_print_backend_unref_at_idle().
* gtk/gtkprinter.[ch]:
GtkPrinter objects now ref their backend so that its always
availible, since its needed for the printer object to work.
This causes a reference-cycle that is broken using
gtk_print_backend_destroy.
Add gtk_printer_compare.
* gtk/gtkprintoperation-private.h:
* gtk/gtkprintoperation-unix.c:
* gtk/gtkprintoperation.c:
Implement !show_dialog for unix.
Make sure the print data is fully spooled before returning
from a sync run_dialog.
* modules/printbackends/cups/gtkcupsutils.[ch]:
Add gtk_cups_request_ipp_add_strings
* modules/printbackends/cups/gtkprintbackendcups.c:
* modules/printbackends/cups/gtkprintercups.c:
* modules/printbackends/lpr/gtkprintbackendlpr.c:
* modules/printbackends/pdf/gtkprintbackendpdf.c:
Convert backends to derive instead of implementing interface.
Move common code into baseclass.
CUPS:
Remove the printer polling in dispose, not finalize.
In the cups watch, remove the backend at idle instead of
immediately, since the unref can cause the module to be unloaded.
Limit the number of printer attributes requested
Get printer uri in initial printer listing so that we can use
the printer object immediately.
* tests/Makefile.am:
* tests/testnouiprint.c:
Add testcase for !show_dialog.
