[GTK] Replace deprecated gdk_pixbuf_new_from_inline()

Use GResource instead, if available. Add autotools and cmake compile time
checks for build requirements (GIO >= 2.32 and GDK-Pixbuf >= 2.26).

Merge all the various static pixbuf csource header files into
a single pixbuf-csource.h header with external linkage through use of the
tools/make-pixbuf-csource.pl script.

Fix inline pixbuf build target for some image paths (broken for GTK
in gb4a4de7).

Add missing 'expert_ok.png' file to distribution (GTK only).

Minor improvements to style/structure of ui/gtk/Makefile.am.
