In order to retrieve the user options for a printer, the respective
printer name is used.
This fixes the comparison of printer names to avoid that the options of
another printer are accidently read whose name starts with the same
letters, but is longer (e.g. "myprinterlongername" instead of
"myprinter").
This fixes Bug 753628.
"Yo, we heard you like traversing NULL-terminated arrays to operate on
them, so we called g_strv_length() as the for condition, so you can
iterate the array while iterating the array."
Instead of making famed rapper and television producer Xzibit proud, we
should avoid calling g_strv_length() on an array while looping on the
array, to avoid quadratic complexity.
We do this in various places that deal with arrays of strings that we
cannot really guess are short enough not to matter — e.g. the list of
CSS selectors in the inspector, or the required authentication
information for printing.
Request "output-bin-supported" and "output-bin-default" attributes through
IPP if there is no PPD for selected printer.
Pass "output-bin" option with other options in printer_get_options().
Translate standard IPP values of "output-bin" option.

Add parameter for specification of port to gtk_cups_connection_cups_new().
Use default port returned by ippPort() if the given port is lower than 0.

If auth_info_required is only set to "negotiate" the
request password dialog is shown anyway for each print
job without any input fields. As the request_password
dialog only handles username, password and domain.

We directly get the length of the secret from the g_variant
and use it in a following g_strndup which ensures that the
resulting string is terminated.
This fixes reading secrets which were stored by system-config-printer.

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.

This is a web service provided by Google that allows people to
share their printers (https://www.google.com/cloudprint/learn/).
In addition to being able to print to printers shared on Google Cloud
Print, there is an equivalent of "Print to file" in the form of "Save to
Google Drive".
The cloudprint module uses gnome-online-accounts to obtain the OAuth 2.0
access token for the Google account.
Currently it can discover available printers, get simple details about
them such as display name and status, and submit jobs without any
special options.

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.

Printing a file with to PDF/etc. with the virtual printer option doesn't add
the file to the list of recently used files. It should be there, so I can
easily access it.

It can happen if the io channel has been closed. In that case
g_io_channel_write_chars() returns early because of a g_return macro
that checks if the io channel is writable. When returning from g_return
macros, the bytes written output parameter is not updated and the error
is not filled, so the error is not detected and the written variable is
used uninitialized. We should check the return value of
g_io_channel_write_chars() to break the loop.

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.
