Enable having some gdk-pixbuf loaders built-in even if loading the others

	* configure.in: Enable having some gdk-pixbuf loaders built-in
	even if loading the others dynamically. Define Automake
	conditional INCLUDE_FOO for each loader as TRUE if that loader is
	built-in. See also gdk-pixbuf/ChangeLog.

	Enable having some loaders built-in even if loading the others
	dynamically. Have loaders in the same order as in configure.in in
	all places where they are handled/listed.

	* Makefile.am: Define the STATIC_FOO_LIB and FOO_LIB macros
	conditionally depending on whether said loader is built-in or
	not. Use the names libstatic-pixbufloader-foo.la instead of
	libpixbufloader-static-foo.la for the built-in ones so that the
	"echo libpixbufloader-*.la" won't match them.

	* gdk-pixbuf-io.c: Reorganize code as to plumb the built-in
	loaders also if USE_GMODULE. Don't warn about a missing
	gdk-pixbuf.loaders file if we have at least one included loader.

	* gdk-pixbuf-private.h
	* io-*.c: Don't define a generic MODULE_ENTRY, as we can't use it
	in the loaders anyway. Each loader needs to check if INCLUDE_foo
	is defined.
