gtk_window_get_group() never returns NULL; if the window isn't in a group,
a default window group is returned instead. Use gtk_window_has_group() instead.
This fixes some previous commits to use accessors to access GtkWindow.

Remove message dialogs showing an error when printing. Return
GTK_PRINT_OPERATION_RESULT_ERROR and set error in such a case.
Also return GTK_PRINT_OPERATION_RESULT_CANCEL when cancelled.
Do it for synchronous and asynchronous cases (#549127).
This commit was created using a script that searched for all docstrings
containing a parameter and the string 'or %NULL'.
Gdk backends and demos excluded as they are not part of a public API

The Gtk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GTK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.
When printing, increment page sequence before rendering of the page,
not after (#590084).
In opposite case it runs "end_page" function with wrong parameters when
drawing a page in another thread.
Paper size combo and orientation combo can be added by
gtk_print_operation_set_embed_page_setup_dialog() to GtkPrinUnixDialog
now. This function induce calling of
gtk_print_unix_dailog_set_embed_page_setup_dialog() after creation of
dialog. These two functions control embed-page-setup-dialog properties
in GtkPrintOperation and in GtkPrintUnixDialog.
There is also new function gtk_print_unix_dialog_get_page_setup_set()
which says whether page setup was set by user.
Selected page setup is stored as default page setup in
GtkPrintOperation.
New class is added, its name is GtkCustomPaperUnixDialog. The class
manages custom sizes. It is derived from GtkPageSetupUnixDialog's
CustomPaperDialog structure.
Page layout preview is modified, so, it shows dimensions of current
page setup (mm or inch - depends on locale). It also shows the name of
actual paper if page setup dialog is not embedded (paper size combo is
not visible).
gtk-demo is actualized to include this new feature.
Add a new radio button "Selection" to the print dialog. Its presence
depends on calling of functions gtk_print_operation_set_support_selection()
and gtk_print_dialog_unix_set_support_selection().
Sensitivity of the radio depends on calling of
functions gtk_print_operation_set_has_selection() and
gtk_print_dialog_unix_set_has_selection().
There are new properties GtkPrintUnixDialog::support-selection,
GtkPrintUnixDialog::has-selection, GtkPrintOperation::support-selection
and GtkPrintOperation::has-selection. Corresponding getters are
gtk_print_dialog_unix_get_support_selection(),
gtk_print_dialog_unix_get_has_selection(),
gtk_print_operation_get_support_selection() and
gtk_print_operation_get_has_selection().
Application has to set number of pages to which the selection will be formated
in GtkPrintOperation::begin-print's callback by the
gtk_print_operation_set_n_pages() function (bug #344519).
There is also new property GtkPrintUnixDialog::manual-capabilities controled by
gtk_print_unix_dialog_set_manual_capabilities() and
gtk_print_unix_dialog_get_manual_capabilities().
