Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.

Make GstObject extend from GInitiallyUnowned, remove the FLOATING flag and use
GObject methods for managing the floating ref.
Remove class lock, it was a workaround for a glib < 2.8 bug.
Remove the parent-set and parent-unset signals, attempt to implement with notify
but disabled because deadlocks in deep-notify.
Adds a new tag to indicate the error in horizontal positioning
in meters. This is one of the available 'gps error' fields in
exif, for example.
API: GST_TAG_GEO_LOCATION_HORIZONTAL_ERROR
Add _set_value() variants that take ownership of the value passed
instead of making a copy of the value. This is useful for setting
values to things that aren't refcounted (e.g. GValueArrays or
strings or string arrays, etc.).
API: gst_structure_take_value()
API: gst_structure_id_take_value()

Add a GstStructure to GstElementClass and GstElementFactory. Add setters/getter.
Handle it in the registry code. Print items in gst-inspect.
Fixes#396774.
API: gst_element_class_set_meta_data(), gst_element_factory_get_meta_data_detail()
Added a new query type to retrieve informations about the areas of the
media currently buffered. See bug 623121.
API: gst_query_add_buffering_range
API: gst_query_get_n_buffering_ranges
API: gst_query_parse_nth_buffering_range
Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.

Adds GST_TAG_APPLICATION_DATA for representing arbitrary private
data that applications might want to store into tags. Exif/id3,
for example, have tags for this.
API: GST_TAG_APPLICATION_DATA
Fixes#626651
For some reason the static inline function GST_CAT_LEVEL_LOG_valist is
now picked up, which then breaks the build because it's not documented,
so add it to the sections file.
Based on patch by Víctor Manuel Jáquez Leal <vjaquez@igalia.com>.
Fixes#625862.
Adds a new tag to inform about the image orientation and how
to rotate and flip it before display.
Note that this tag is a string with a predefined set of
possible values.
API: GST_TAG_IMAGE_ORIENTATION
Fixes#619508
A pad is 'negotiable' when its container element is in a state greater
than GST_STATE_READY

This allows removing structures from caps without them being freed. Helpful when
plugins need to move around structures without having to do an expensive structure
copy.

This makes it possible to easily get a *:5 debug log without all
the refcounting noise, and drastically reduces the number of lines
output for a normal log (46m to 28m for a 20min video). The full log
including refcounting information can still be gotten using *:7.
Fixes#620460.
Adds 3 new geo location tags involving direction and
movement of capture. Those are:
API: GST_TAG_GEO_LOCATION_CAPTURE_DIRECTION
API: GST_TAG_GEO_LOCATION_MOVEMENT_DIRECTION
API: GST_TAG_GEO_LOCATION_MOVEMENT_SPEED
Fixes#617223
Adds those new tags to describe the device manufacturer and
model used to create medias.
API: GST_TAG_DEVICE_MANUFACTURER
API: GST_TAG_DEVICE_MODEL
Fixes#615941
Adds a new tag for user favorite media rating.
User rating informs how much (from 0 to 100) a user
'likes' a media.
Having an percent uint range for this is easy to map into other scales,
like some players that allow users to attribute 'stars' to its
media.
API: GST_TAG_USER_RATING
Fixes#520697
