458e3b7a84 value: Allow automatic transforms to/from interfaces
Use the new g_type_interface_instantiable_prerequisite() to check
compatibility for transform functions.

In particular, this allows interfaces (in my case GDK_TYPE_PAINTABLE) to
be transformed to/from any GObject type (in my case G_TYPE_OBJECT) using
the transform function registered to transform between any 2 objects
(g_value_object_transform_value() does a type check and uses NULL if the
types don't match).

And this in turn allows be to g_object_bind_property() a gobject-typed
generic property (GtkListItem::item) to a GtkImage::paintable.

Tests for the new functionality are included.

18a33f72db introspection: use (nullable) or (optional) instead of (allow-none)
If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.

It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.

25a7c817d3 glib: Add missing (nullable) and (optional) annotations
Add various (nullable) and (optional) annotations which were missing
from a variety of functions. Also port a couple of existing (allow-none)
annotations in the same files to use (nullable) and (optional) as
appropriate instead.

Secondly, add various (not nullable) annotations as needed by the new
default in gobject-introspection of marking gpointers as (nullable). See
https://bugzilla.gnome.org/show_bug.cgi?id=729660.

This includes adding some stub documentation comments for the
assertion macro error functions, which weren’t previously documented.
The new comments are purely to allow for annotations, and hence are
marked as (skip) to prevent the symbols appearing in the GIR file.

3c0d38d68b gvalue: Improve _unset() documentation
g_value_unset() only works with initialized value and will assert
if the GValue is zero-filled (or initialized with G_VALUE_INIT). Document
this behaviour and refer to g_value_clear() for a method that work on
both initialized and zero-filled GValue.

c5c3c320a2 gvalue: New g_value_init_from_instance
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

4b94c0831e Use 'dumb quotes' rather than `really dumb quotes'
Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.

However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.

Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.

Fix this by just using 'dumb quotes' everywhere.

d2ca14c270 Add G_VALUE_INIT
The implementation of GValue is not public or documented.  When
allocated on the stack, initializing a GValue is usually done as
documented with:

GValue value = { 0, };

There is lot code around (including WebKit) that added all the missing
fields, resulting in this ugly and non-obvious:

GValue value = { 0, { { 0 } } };

However, this doesn't play nice with -Wmissing-field-initializers for
example. Thus, G_VALUE_INIT.

2d75227eb1 reverted a change to have an assert instead of a g_return_val_if_fail()
Mon Oct  2 15:50:16 2006  Tim Janik  <timj@gtk.org>

        * gvalue.c (g_value_peek_pointer): reverted a change to have an
        assert instead of a g_return_val_if_fail() here. libraries (and
        programs) should only ever g_assert or g_error if there is no way
        to carry on with the current program state. that's clearly not
        the case here.
