(standard_definitions): Add a few query types, deprecate a few. (gst_query_get_type): New proc. (_gst_query_copy, _gst_query_free, gst_query_new): GstData implementation. (gst_query_new_application, gst_query_get_structure): New public procs. * docs/design/draft-query.txt: Removed LINKS from the query types, because all the rest can be dispatched to other pads -- seemed ugly to have a query that couldn't be dispatched. internal_links is fine as a pad method. * gst/gstpad.h: Add query2 as a pad method, add the new functions in gstpad.c, but maintain binary compatibility for the moment. Will fix before 0.9 is out. * gst/gstqueryutils.c: * gst/gstqueryutils.h: New files, implement 3 methods for each query type: parse_query, parse_response, and set. Probably need an allocator as well. * gst/gst.h: Add gstquery.h and gstqueryutils.h to the list. * gst/elements/gstfilesink.c (gst_filesink_query2): * gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query, query_types, and formats methods. * gst/gstpad.c (gst_pad_query2, gst_pad_query2_default) (gst_pad_set_query2_function): New functions.

/* refcounting */
Convert unref/copy functions of GstMiniObject subclasses to static inline functions unref and copy functions are sometimes used as function pointers for example in the case of g_hash_table_new_full as a GDestroyNotify function. Currently GstBuffer, GstEvent, GstMessage and GstQuery define their respective unref and copy functions as macros, making use of gst_mini_object_unref/copy. This approach works very well for most cases, except for some automatically generated bindings (currently Vala), where the memory management semantics are defined declaratively. The possible solutions would be to either convert all the macros into static inline function, or change the signature of gst_mini_object_unref to take a void* instead of a GstMiniObject*. Fixes bug #572480.

(gst_real_pad_init): Set query2_default as the default query2 function. Basically just dispatches to internally linked pads.

/* copy query */
Convert unref/copy functions of GstMiniObject subclasses to static inline functions unref and copy functions are sometimes used as function pointers for example in the case of g_hash_table_new_full as a GDestroyNotify function. Currently GstBuffer, GstEvent, GstMessage and GstQuery define their respective unref and copy functions as macros, making use of gst_mini_object_unref/copy. This approach works very well for most cases, except for some automatically generated bindings (currently Vala), where the memory management semantics are defined declaratively. The possible solutions would be to either convert all the macros into static inline function, or change the signature of gst_mini_object_unref to take a void* instead of a GstMiniObject*.

pad: remove getcaps and use caps query Remove the getcaps function on the pad and use the CAPS query for the same effect. Add PROXY_CAPS to the pad flags. This instructs the default caps event and query handlers to pass on the CAPS related queries and events. This simplifies a lot of elements that passtrough caps negotiation. Make two utility functions to proxy caps queries and aggregate the result. Needs to use the pad forward function instead later.

Original commit message from CVS: - major API breakage (one of the last, I promise...) - GST_PAD_QUERY -> GST_QUERY - GstPadQuery -> GstQuery - Move query definitions to gstquery.h to allow for future dynamic query types. - remove _pad_handles_* in favour of extra format/event functions to make the same checks. - fix elements - Implemented missing query/event/formats functions in gstelement
