Support 'symbolic' themed icons

Add gtk_icon_info_load_symbolic() to load symbolic icons, and
theme their background/foreground colours to match the
colours used in the theme.

Adds the gtk_icon_info_load_symbolic() function, explicit
support in GtkImage and GtkCellRendererPixbuf, and test cases
for those 2 widgets.

With help from Bastien Nocera <hadess@hadess.net>

* @error_color: (allow-none): a #GdkColor representing the error color of the icon

* @was_symbolic: (allow-none): a #gboolean, returns whether the loaded icon was a symbolic
* one and whether the @fg color was applied to it.
* @error: (allow-none): location to store error information on failure, or %NULL.
*
* Loads an icon, modifying it to match the system colours for the foreground,
* success, warning and error colors provided. If the icon is not a symbolic one,
* the function will return the result from gtk_icon_info_load_icon().
*
* This allows loading symbolic icons that will match the system theme.
*
* Unless you are implementing a widget, you will want to use
* g_themed_icon_new_with_default_fallbacks() to load the icon.
*
* As implementation details, the icon loaded needs to be of SVG type,
* contain the "symbolic" term as the last chunk of the icon name,
* and use the fg, success, warning and error styles in the SVG file itself.
* See the <a ulink url="http://www.freedesktop.org/wiki/SymbolicIcons">Symbolic Icons spec</ulink>
* for more information about symbolic icons.
*
* Return value: a #GdkPixbuf representing the loaded icon
