Use g_string_assign to avoid issues with assigning GString's internal
buffer back to the same string. This can happen when no translations are
available and _gtk_builder_parser_translate returns back the same
pointer that was passed in.
This fixes a regression from commit e9f182e37a
that caused GtkComboBoxText <items> from GtkBuilder to show up empty if
no translations are available.

Also removed a bogus FIXME comment which might have been true
a long time ago. Clarification: the "domain" attribute specified
in the builder script overrides any domain previously set with
gtk_builder_set_translation_domain(), so the translation of items
here is perfectly correct and does not need to be fixed.

The fix here is slightly different. We make
_gtk_builder_parser_translate return a const char * instead of
a dup'ed string, and fix up the callers.
Presently, GtkComboBoxText lets you list the items for it in the
GtkBuilder markup like so:
<items>
<item translatable='yes'>Red</item>
<item translatable='yes'>Blue</item>
</items>
but has no way to set the "id" column for added items. Add an id='' tag
for that purpose so that you can do:
<item id='red' translatable='yes'>Red</item>
https://bugzilla.gnome.org/show_bug.cgi?id=667319
If the GtkComboBoxText doesn't have id-column or entry-text-column
set for some reason (value -1), better warn and return. Else, unrelated
assertions fail, and warnings from gtk_tree_model_get_column_type()
are printed, which are not really obvious.

Based on a patch by Matthias, add an "active-id" property for
GtkComboBox and add some convenience API for GtkComboBoxText.
Also, add a test case to gtk-demo.
This is a derived class of GtkComboBox to replace the
gtk_combo_box_*_text() convenience API.
