	* autogen.sh: check for pkg.m4.

	* configure.in: removed logic to extract GLIB CFLAGS and LDFLAGS
	from the GTK CFLAGS and LDFLAGS. Use AM_PATH_GLIB_2_0() instead.
	This change will break things on awfully misconfigured systems.
	Simplified the checks and moved version numbers to the top to ease
	maintainance. Check if gtk-doc is suffiently new.

	* app/main.c: removed the GimpConfig test code.

	* app/config/Makefile.am
	* app/config/test-config.c: added a (yet very small) standalone test
	suite for GimpConfig.

	* app/config/gimpconfig.[ch]
	* app/config/gimpconfig-deserialize.[ch]: allow to specify if
	unknown tokens should be stored or should cause a parser error.
	Changed code to store unknown tokens to use a list since a hash
	table seems to be overkill here.
