• Remove copies of function declarations from the explanation — if
people want those, they can follow links to the reference manual.
• Add markup to make C code more defined.
• Remove use of first person and irrelevant name dropping.

So that first-time users don’t fall into the trap of reading about the
gory memory layout details of GType and GObject when all they wanted to
do was derive a class.
https://bugzilla.gnome.org/show_bug.cgi?id=744060
Use G_DECLARE_INTERFACE and G_DEFINE_INTERFACE. Fix a couple of typos.
Add some comments to empty functions to make it obvious they’re
intentionally empty.
https://bugzilla.gnome.org/show_bug.cgi?id=744060
Restructure the section of the how-to which covers the header and source
code boilerplate for declaring and defining GObjects to use the new
G_DECLARE_*_TYPE macros. Present both final and derivable types.
Trim various supporting paragraphs.
Rename ‘class functions’ to ‘virtual functions’ to use consistent,
modern terminology.

Make it a little easier to find the GType conventions page, which I
guess should be the canonical guide to how to name things.
This adds a brief mention of the valid characters in a type name to the
conventions page.

Add G_DECLARE_DERIVABLE_TYPE() and G_DECLARE_FINAL_TYPE() to allow
skipping almost all of the typical GObject boilerplate code.
These macros make some assumptions about GObject best practice that mean
that they may not be usable with older classes that have to preserve
API/ABI compatibility with a time before these practices existed.

Along the same lines as g_clear_object(), g_set_object() is a
convenience function to update a GObject pointer, handling reference
counting transparently and correctly.
Specifically, it handles the case where a pointer is set to its current
value. If handled naïvely, that could result in the object instance
being finalised. In the following code, that happens when
(my_obj == new_value) and the object has a single reference:
g_clear_object (&my_obj);
my_obj = g_object_ref (new_value);
It also simplifies boilerplate code such as set_property()
implementations, which are otherwise long and boring.
Test cases included.

Used for the commonly used case (in signal emission) where we
initialize and set a GValue for an instance
Includes a fast-path for GObject
Overall makes it 6 times faster than the previous combination
of g_value_init + g_value_set_instance
Makes signal emission around 10% faster

On initialisation, GObject guarantees to zero-fill
class/object/interface structures. Document this so people don’t spend
forever writing:
my_object->priv->some_member = NULL;
my_object->priv->some_other_member = NULL;

Since all element markup is now gone from the doc comments,
we can turn off the gtk-doc sgml mode, which means that from
now on, docbook markup is no longer allowed in doc comments.
To make this possible, we have to replace all remaining
entities in doc comments by their replacement text, & -> &
and so on.
This is really just a very crude and limited conditional breakpoint.
Update the documentation to explain conditional breakpoints in
gdb instead. Also, remove the link to refdbg, which appears dead.

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
