Original commit message from CVS: * gst/gstcaps.c: (gst_caps_from_string_inplace): fix bug when converting from empty string. * gst/gstcaps.c: (gst_caps_new_any), (gst_caps_new_simple), (gst_caps_new_full_valist), (gst_caps_copy), (gst_caps_copy_1): use gst_caps_new_empty to allocate a new caps. Only that function allocates memory for caps now. * gst/gstcaps.c: (gst_caps_remove_and_get_structure), (gst_caps_remove_structure): add ability to remove one structure (but not to header yet) * gst/gstcaps.c: (gst_caps_compare_structures), (gst_caps_simplify), (gst_caps_structure_figure_out_union), (gst_caps_structure_simplify), (gst_caps_do_simplify), * gst/gstcaps.h: add gst_caps_do_simplify that tries to simplify a caps in place. Deprecate old gst_caps_simplify function. * testsuite/caps/caps.h: add caps.h containing a common set of caps to test against. * testsuite/caps/sets.c: (check_caps), (main): use it. * testsuite/caps/.cvsignore: * testsuite/caps/Makefile.am: * testsuite/caps/simplify.c: (check_caps), (main): add test to check correctness and efficency of caps simplification.
