Migrating away from GtkStock stuff

[Gabriele Greco <gabriele greco wyscout com>]

Hi guys,

I'm in the process of migrating a big code base from GTK 2.x to GTK 3.x,
I've done most of the work, but I'm facing now some problems with GTK stock
stuff.

I used stock stuff a lot to reduce the localizable strings needed in my
code and to reduce the number of images to ship.

> From what I've seen there are no more stock items in GTK 3 (3.24.2 at the
moment), since they have been deprecated in 3.10.

It's more a removal than a deprecation since my code compiles but the
program seems to fail to find at least the icons pointed by the stock item:

(<unknown>:75970): Gtk-WARNING **: 12:47:16.541: Error loading theme icon
'document-new' for stock: Icon 'document-new' not present in theme Adwaita
(<unknown>:75970): Gtk-WARNING **: 12:47:16.598: Error loading theme icon
'document-open' for stock: Icon 'document-open' not present in theme Adwaita
(<unknown>:75970): Gtk-WARNING **: 12:47:16.599: Error loading theme icon
'document-save' for stock: Icon 'document-save' not present in theme Adwaita
(<unknown>:75970): Gtk-WARNING **: 12:47:16.599: Error loading theme icon
'edit-find' for stock: Icon 'edit-find' not present in theme Adwaita

There is a stack overflow post that suggests how to handle the migration
from a GtkStock item to a "named icon" or a "gtk localized label":

... but what about toolbar or buttons that given the theme may have icons,
labels or both?
