Introduced new function type GEqualFunc to return TRUE for equal params.

	* gcache.h, gcache.c, ghash.h, ghash.c, grel.c, grel.h, gtypes.h:
	Introduced new function type GEqualFunc to return TRUE for equal
	params. This is now used instead of GCompareFunc (which should
	work akin to strcmp) here. This kind of fixes Bug #14412. Note
	that technically GCompareFunc and GEqualFunc are still the same
	types, as gint == gboolean.

	* ghash.h, gutils.c: g_int_equal and g_direct_equal now return
	gboolean to be really become GEqualFunc.

	* gscanner.c, testglib.c, tests/hash-test.c: Some tiny changes to
	follow the above change.
