9fa4c67632 gi: Skip mini object method that play with refcounting
It make no sense to allow using that. Any use would lead to leak
of crash. Note that GMiniObject is entirely unusable as you cannot
cast from let's say GstBuffer to GstMiniObject.

ad4569c893 miniobject: disallow a double write/exclusive lock
gst_memory_lock (mem, WRITE | EXCLUSIVE);
gst_memory_lock (mem, WRITE | EXCLUSIVE);

Succeeds when the part-miniobject.txt design doc suggests that this should fail:

  "A gst_mini_object_lock() can fail when a WRITE lock is requested and
  the exclusive counter is > 1. Indeed a GstMiniObject object with an
  exclusive counter 1 is locked EXCLUSIVELY by at least 2 objects and is
  therefore not writable."

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6eb6d9ec38 docs: remove outdated and pointless 'Last reviewed' lines from docs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.

Remove trace, we use debug log for that
Make alloc trace simpler, removing some methods.

Dump leaked objects atexit.
Provide an offset in the object where the GType can be found so that more
verbose info can be given for objects.
Remove -T option from gst-launch because tracing is now triggered with the
environment variable.

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.

ee235a6b07 miniobject: avoid race in bufferpool release
Avoid playing with the refcount to decide when a buffer has been recycled by the
dispose function. The problem is that we then temporarily can have a buffer with
a refcount > 1 being acquired from the pool, which is not writable. Instead use
a simple boolean return value from the dispose function to inform the called
that the object was recycled or not.

cf671d7b0a miniobject: Add weak referencing functionality
API: gst_mini_object_weak_ref()
API: gst_mini_object_weak_unref()

Add weak referencing functionality to GstMiniObject, which
allows to get notifications when an mini object is destroyed
but doesn't increase the real refcount. This is mostly
useful for bindings.

Fixes bug #609473.
