Upgrade to GTK+ 1.2.3, and bump shared library numbers.

	Major changes:
	 - USE_LIBTOOL.  Major decrease in patching...
	 - Don't always link with thread flags.  No longer means that GTK+
	   is always linked with libc_r.

	Other ports:
	 - Changed depenancies
	 - USE_LIBTOOL
	 - Sane: Fix PLIST.
	 - gFTP: Proper use of -pthread.
	 - gtkportscan: Use $PREFIX.
	 - pdq: Add MESSAGE to package.
	 - gtk--: Use egcs on < 4.0 (Closes ports/11776).

	Note:  I've not contact maintainers.  I've lost track...
