[gtkada] Heap corruption and other problems

[Dmitry A. Kazakov]

1. It seems that Gtk3 up to version 3.8 (Glib 2.36) has serious problem
which corrupts Ada's memory pool sooner or later. The bug is sporadic and I
cannot track it down, especially without building Glib from sources, which
is a problem itself.

2. Another serious problem is in GDK which shows itself as:

   Gdk-CRITICAL **: gdk_device_get_source: assertion `GDK_IS_DEVICE
(device)' failed

on many occasions. E.g. in combo boxes after resizing them.

So far Gtk3 looks barely usable for any serious application. Sorry for all
efforts AdaCore spent on GtkAda.
