bug#3043: 23.0.92; GtkFileSelection is deprecated

[Sven Joachim]

Emacs uses GtkFileSelection in gtkutil.c which has been deprecated in
GTK+ 2.12.  That means that it will not build with a future GTK+ 3.0,
or with -DGTK_DISABLE_DEPRECATED in a current GTK+ 2.x.

This problem is not urgent, but it would be good if gtkutil.c could use
the GtkFileChooser interface instead.

Actually Emacs has used GtkFileChooser by default for a long time now, more or 
less since it became available in a stable Gtk+ release.  But if both are 
available, GtkFileSelection can be used (I don't remember the customize 
variable for it right now).  There is a configure test for both file dialogs, 
so if one is removed in 3.0, Emacs will compile just fine.  However, as 
configure just looks at link time symbols, we might not do the right thing 
when compiled with -DGTK_DISABLE_DEPRECATED.  I'll check this.

I have checked in a better configure test and some other minor changes so
Emacs compiles with -DGTK_DISABLE_DEPRECATED.

Actually, Emacs does support the new GTK file chooser.  It's used if
HAVE_GTK_FILE_CHOOSER_DIALOG_NEW is defined, which is set by configure
upon checking the existence of the function gtk_file_chooser_dialog_new.
Is it not available on your system?

It is, and HAVE_GTK_FILE_CHOOSER_DIALOG_NEW is defined.  However,
HAVE_GTK_FILE_BOTH and HAVE_GTK_FILE_SELECTION_NEW are also defined
which might explain the problem.

I built with 

,----
| make distclean
| CFLAGS=-DGTK_DISABLE_DEPRECATED -g -O2 ./configure
| make -k
`----

and ran into

,----
