consumed by bindings

6fa351407a miniobject: Add parent pointers to the miniobject to influence writability
Every container of miniobjects now needs to store itself as parent in
the child object, and remove itself again at a later time.

A miniobject is only writable if there is at most one parent, and that
parent is writable itself, and if the reference count of the miniobject
is 1.

GstBuffer (for memories), GstBufferList (for buffers) and GstSample (for
caps, buffer, bufferlist) was updated accordingly.

Without this it was possible to have e.g. a bufferlist with refcount 2
in two places, modifying the same buffer with refcount 1 at the same
time.

ed5d888ba5 gstsample: new API
gst_sample_set_buffer
gst_sample_set_caps
gst_sample_set_segment
gst_sample_set_info
gst_sample_is_writable
gst_sample_make_writable

This commit makes it possible to reuse a sample object and avoid
unnecessary memory allocations, for example in appsink.

In addition, writability is now required to set the buffer list.

b5028383ab gst: Fix up a bunch of GIR annotations
This is mostly on nullable return values, and some other minor ones that
I ran across.

2759882379 introspection: add missing (nullable) annotations to return values
Support for (nullable) was added to G-I at the same time as nullable
return values.  Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

6eb6d9ec38 docs: remove outdated and pointless 'Last reviewed' lines from docs
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

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.

1be934f0dd miniobjects: pass copy, dispose and free function to gst_mini_object_init()
So mini objects don't have to poke into the GstMiniObject part
of the structure. Saves lines of code, and seems slightly cleaner.
We don't have proper OO hierarchies or methods here after all.

12aefaa078 miniobject: remove the size field
The size field is used by subclasses to store the total allocated size of the
memory for this miniobject. Because miniobject doesn't really do anything with
this field we can move it to the subclasses.

5477399881 sample: remove const
The writability of the structure is ensured by the refcount of the parent
miniobject and we're fine if the parent is writable.

facf937276 sample: add new sample miniobject
Add a new simple miniobject that is a combination of a GstBuffer, GstCaps,
GstSegment and other arbitrary info organized in a GstStructure. This object can
be used to exchange samples between an element and the application or for
storing album art in tags etc.
