Request "sides-supported" and "sides-default" attributes through
IPP if there is no PPD for selected printer.
Pass "sides" option with other options in printer_get_options().
Add function setup_ipp_option() for creating of IPP option
of given name with passed choices and default value.
Mark such an option as "is-ipp-option" so we can distinguish it
later.

Query printer via IPP for paper sizes if there is no
or empty PPD file.
Parse "media-supported" and "media-size-supported" attributes for list
of paper sizes. Parse "media-default" and "media-col-default" attributes
for default settings.

Remove checks for NULL before g_free() and g_clear_object().
Merge check for NULL, freeing of pointer and its setting
to NULL by g_clear_pointer().

When a printer requires auth_info (e.g. a printer connected
over the samba protocol) it is now possible to save the
credentials necessary for printing if a secrets service
is available over dbus.
The auth_info is then stored / loaded from the default
collection of that secrets service.
If no such service is available the user is not shown
the option to remember the password and the behavior
remains the same as before.

Return values of g_variant_get_child_value() were not unreffed
correctly together with one value returned by g_variant_get().
Use g_variant_get_data() instead of copying each byte separately.

Use info available in Avahi TXT records for creation of gtk printer
and request details when needed (through gtk_printer_request_details()).
If there is a printer advertised on Avahi by a remote CUPS server
try to get its PPD file at first or get its capabilities through an IPP
request if it fails.

In avahi_request_printer_list() a new connection to the DBus system bus
is started asynchronously, but it's not cancellable and it's not taking
any reference of the GtkPrintBackendCups. This means that when the
callback is called, the object might have been destroyed already. We can
just pass the cancellable created and check for the cancelled error in
the callback before trying to use the GtkPrintBackendCups. The code to
cancel avahi operations and to unsibscribe from the DBus signals has
been moved from finalize to dispose to make sure it happens as soon as
possible.
https://bugzilla.gnome.org/show_bug.cgi?id=696553
If GtkPrintBackendCups is finalized and cups_get_printer_list hasn't
been called, g_object_unref is called for the GDBusConnection pointer
that is NULL. Use g_clear_object() instead.

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.

gtk+ was trying to display already freed strings, leaking memory,
...I noticed this because I was getting weird blinking characters
as the status of my cups printers, and valgrind confirmed something
was wrong.

These are just wrappers for the functions, and we want to
deprecate them. Stopping to use them internally is a good
first step. Also define GTK_COMPILATION so we can keep using
gdk_threads_enter/leave without causing deprecation warnings.
Having refactored cups_request_printer_list_cb so that the cups
version-dependent block size is small enough to be handled in a single ifdef,
make the ifdef HAVE_CUPS_API_1_6 block.
So that it can be passed as a single parameter to functions as we extract-function to make cups_request_printer_list_cb more manageable.
Note that not all of the affected variables are changed in this changeset. Those are in extracted functions and will be addressed in the next two changes.
