7477b25df5 caps: Add new data type for handling caps features to the caps
These are meant to specify features in caps that are required
for a specific structure, for example a specific memory type
or meta.

Semantically they could be though of as an extension of the media
type name of the structures and are handled exactly like that.

3b16efa1d1 miniobject: add lock functionality to GstMiniObject
Move the locking methods from GstMemory to GstMiniObject.
Add a miniobject flag to enable LOCKABLE objects. LOCKABLE objects can
use the lock/unlock API to control the access to the object.
Add a minobject flag that allows you to lock an object in readonly mode.
Modify the _is_writable() method to check the shared counter for LOCKABLE
objects. This allows us to control writability separately from the refcount for
LOCKABLE objects.

272142089e caps: remove gst_caps_union()
Remove gst_caps_union(), use gst_caps_merge(). This function was not used
anymore and it is unclear what the difference is with _merge().

8a76c3269a caps: _do_simplify() -> _simplify()
Rename _do_simplify() to _simplify(). The name was introduced as a replacement
method for a deprecated method but we can now rename it again.

9cdbffea94 caps: improve _do_simplify
Make gst_caps_do_simplify() take ownership of the input caps and produce a
simplified output caps. This removes the requirement of having writable input
caps and the method can make the caps writable only when needed.

43abf99a8a caps: avoid using in-place oprations
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.

8ff059ba59 caps: add ANY and EMPTY singletons
Add a singleton for ANY and EMPTY caps and make the GST_CAPS_ANY and
GST_CAPS_NONE point to them. This makes the API more consistent now
that the macro does not magically create a ref. It also solves some leaks in
places where the macro was used to register a padtemplate.

f3b0d3cdbe init: add _get_type() functions
Remove gst_mini_object_register() and add a GST_DEFINE_MINI_OBJECT macro to
define a _get_type() function for the boxed miniobject.
Remove a bunch of custom _get_type() functions and replace them with the
miniobject macro.
Rename some _init method to _priv_*_initialize() like the rest of them.

this, to avoid frustration. See countless bug reports in bugzilla.

31832d3c21 caps: Use G_GNUC_WARN_UNUSED_RESULT for make_writable()
People often call
  gst_caps_make_writable (caps);
instead of
  caps = gst_caps_make_writable (caps);
and cause a bug. Warning about an unused return value helps here.

0ff4086507 Improve caps setters API
This patch adds gst_caps_set_value() and allows gst_caps_set_simple() to
work on non-simple caps. See the API documentation for the functions
about what they do.

The intention of these changes is to ease working with caps in caps
transform functions. An example for this would be ffmpegcolorspace,
where the caps transform function could be changed to look roughly like
this (pseudocode ahead):
  result = gst_caps_copy (template_caps);
  value = gst_structure_get_value (gst_caps_get_structure (caps, 0),
    "widh");
  gst_caps_set_value (result, value);
  /* same for height, framerate and par */
  return caps;
which is much cleaner and easier to understand than the current code.
