Add internal helpers for pre-registering quarks from static strings
and using the quark values directly instead of looking them up when
creating and parsing queries. Can be used for event construction too.
Closes #350432.

Original commit message from CVS:
2005-05-06 Andy Wingo <wingo@pobox.com>
* gst/gstquery.h
* gst/gstquery.c (_gst_query_initialize): Extend GstQuery from
GstData, init a memchunk.
(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.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.
Needs review!
* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.

gst/gstquery.h
Original commit message from CVS:
2005-05-06 Andy Wingo <wingo@pobox.com>
* gst/gstquery.h
* gst/gstquery.c (_gst_query_initialize): Extend GstQuery from
GstData, init a memchunk.
(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.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.
Needs review!
* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.

Base value in segment query is not needed.

Original commit message from CVS:

* gst/elements/gsttypefindelement.c:
(gst_type_find_handle_src_query), (find_element_get_length),

API change fix.

(gst_query_new_duration), (gst_query_set_duration),

(gst_query_parse_segment):
* gst/gstquery.h:
Bundling query position/duration is not a good idea since duration
does not change much and we don't want to recalculate it for every
position query, so they are separated again..
Base value in segment query is not needed.
* gst/gstqueue.c: (gst_queue_handle_src_query):
* gst/gstutils.c: (gst_element_query_position),
(gst_element_query_duration), (gst_pad_query_position),
(gst_pad_query_duration):
* gst/gstutils.h:
Updates for query API change.
Added some docs here and there.

* gst/gstquery.h
* gst/gstquery.c (_gst_query_initialize): Extend GstQuery from
GstData, init a memchunk.
(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_pad_set_query2_function): New functions.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.
Needs review!
* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.

(gst_pad_set_query2_function): New functions.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.
Needs review!
* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.
