Original commit message from CVS: * gst/elements/gstmultifilesrc.c: (gst_multifilesrc_class_init): Use G_TYPE_STRING in signal prototype instead of G_TYPE_POINTER. * gst/elements/gsttypefind.c: (gst_type_find_element_class_init): Use GST_TYPE_CAPS in signal prototype. * gst/gstcaps.c: (_gst_caps_initialize), (gst_caps_copy_conditional): Convert GST_TYPE_CAPS to boxed. * gst/gstelement.c: (gst_element_class_init): Use GST_TYPE_TAG_LIST in signal prototype. * gst/gstindex.c: (gst_index_class_init): * gst/gstindex.h: Add GST_TYPE_INDEX_ENTRY type. * gst/gstmarshal.list: Add necessary marshal types. * gst/gstpad.c: (gst_real_pad_class_init), (_gst_real_pad_fixate_accumulator), (gst_pad_link_fixate), (gst_pad_recover_caps_error): Use GST_TYPE_CAPS in signal prototypes. Fix some debugging strings. * gst/gststructure.c: (_gst_structure_initialize), (gst_structure_copy), (_gst_structure_copy_conditional): * gst/gststructure.h: Convert GST_TYPE_STRUCTURE to boxed. * gst/gsttag.c: (gst_tag_list_get_type): * gst/gsttag.h: Add GST_TYPE_TAG_LIST type.
