Commit message

Use "insert" signal instead of "child-added" (LP: #1203888)

In recent Gtk+2 versions, the "insert" signal has been backported from
Gtk+3. This replaces the "child-added" signal, which was carried in an
Ubuntu-specific patch and was dropped in Saucy.

Description of the change

This change removes the special case logic for "insert"/"child-added" since it is no longer needed on current Gtk2.

The full details are in

For a test case see

If libdbusmenu is broken, you will only see "One" in the appindicator menu, and the warning about "child-added". If it is working you will see "One" and "Two".

The tl;dr version:

 * libdbusmenu needed to know when items were added to a GtkMenu. There was no signal for this in Gtk2, so Ubuntu invented one called "child-added" and carried it in a patch called 072_indicator_menu_update.patch:

 * Gtk3 came out, and it had a signal for this purpose called "insert", so libdbusmenu was patched with a piece of logic to detect Gtk2/3 and use the appropriate signal name:

 * Later, the "insert" signal was backported to Gtk2:

 * The Ubuntu "child-added" patch was subsequently dropped in Saucy, but libdbusmenu was not updated to use the "insert" signal with Gtk2.
