GtkSharp/generator/StructField.cs
Dan Winship b6d7f14268 * generator/StructBase.cs: update field-generation logic a bit
* generator/CodeGenerator.cs: add a --glue-includes flag

	* generator/GenerationInfo.cs: Accept glue_includes value from
	Main and output it to the glue_filename.

	* generator/FieldBase.cs (Ignored): handle more ignorable cases.
	(CheckGlue): New method to figure out what kind of glue we'll need
	for a field.
	(GenerateImports): generate appropriate imports per CheckGlue.
	(GenerateGlue): Generate C glue for accessing a struct field;
	either a fully-C-based accessor, or a method to just return the
	field's offset in the struct.
	(Generate): Use the generated glue to read the field.

	* generator/PropertyBase.cs (CType): if the field is a single bit,
	set its type to gboolean.

	* generator/ObjectGen.cs (Generate):
	* generator/OpaqueGen.cs (Generate): Call GenFields.

	* generator/StructField.cs: Use FieldBase's glue-generation code
	to handle bitfields. [#54489]

	* generator/ObjectField.cs: Generates accessors for public fields
	of objects and opaque structs. [#69514]

	* generator/ClassBase.cs (ClassBase): Parse <fields> nodes and
	create ObjectField objects.
	(GenFields): Output field properties
	(IgnoreMethod): Ignore Get/Set methods that duplicate fields

	* generator/Makefile.am (sources): update

	* {gdk,gnome,gtk,pango}/*.metadata: Mark some additional fields as
	public. Rename/retype some fields for consistency with earlier
	hand-coded bindings.

	* {gdk,gnome,gtk,pango}/*.custom: Remove custom methods that can
	now be autogenerated.

	* {gdk,gnome,gtk,pango}/glue/*.c: Remove glue methods that can now
	be autogenerated
	
	* {gdk,glade,gnome,gtk,pango,vte}/Makefile.am
	* {gdk,glade,gnome,gtk,pango,vte}/glue/Makefile.am
	* {gdk,gnome,gtk,pango}/glue/makefile.win32: Update
