David Schleef 67455089a4 gst/elements/gstmultifilesrc.c: Use G_TYPE_STRING in signal prototype instead of G_TYPE_POINTER.
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.
