	Add hidden aliases for exported symbols which are
	used internally in order to get rid of many PLT
	entries.  (#145519, Arjan van de Ven)

	* gtk/Makefile.am: Add rules to generate gtk.def and
	from gtk.symbols, and make make check check the abi
	with abicheck.sh.
	(gtk_private_h_sources): Add gtkinternals.h
	(gtk_built_private_headers): Add gtkalias.h
	(gtk_extra_sources): Add gtk.symbols
	(EXTRA_DIST): Add makegtkalias.pl and abicheck.sh

	* gtk/gtk.symbols: New file. Definition of the GTK+ ABI.
	The file can be processed by cpp to filter out certain
	subsets of symbols.

	* gtk/abicheck.sh: New file. Script to check the actually
	symbols exported from libgtk-x11.2.0.so against the symbols
	found in gtk.symbols.

	* gtk/makegtkalias.pl: New file. Perl script to generate the
	header containing the alias definitions for internally used
	exported symbols from a list of symbols.

	* gtk/gtkinternals.h: New file. An uninstalled header listing
	symbols which must be exported for some reason and do not appear
	in any other header.

	* gtk/*.c: Include gtkalias.h
