Don't use a GtkIconSet to pick the logo image

Just use the first pixbuf in the default list.
Deprecate GtkIconFactory, GtkIconSet, GtkIconSource

We want to use GtkIconTheme instead. It is worth noting that
the parts that remain undeprecated are GtkIconSize and gtk_icon_size_lookup.
Fixup some of the example widgets used in the docs
Disable primary paste by default
Fix default value of scrolled window placement-set property

To make the testsuite happy.

menushell: don't activate a menu entry when opening a big menu

If a menu is opened and it doesn't fit entirely below or above
the menu bar, gtk+ will place it on top. The button release will
then activate the popup item that happens to appear under the
cursor. Avoid this by ignoring release events if they originated
in the parent menu bar and the duration of the press was too short.

Make ignored settings be set to false by default
Deprecate the gtk stock functions
Deprecate GtkImageMenuItem

Use GtkMenuItem for menus with only text or GMenu for those
with icons for "nouns" and just text for "verbs".
Fix the build

We have to uglify the deprecation messages to make gtk-doc
handle them. The get turned into XML attributes, and there
is no automatic quoting to protect quotes in the text.
Trivial rewording

Make the listbox demo follow the naming convention of the
other demos.
testheaderbar: fix a mmemonic
Add a gtk_window_close function

This is useful when adding close buttons in custom titlebars.

csd: Improve the window title

Manually create the label, so that we can set its margins.
csd: Use a dedicated style class for window buttons

This allows themes to differentiate between regular buttons
in a title bar, and window buttons.
