Dan Winship eb4fdee774 Automatic memory management for opaque types [#49565]
* glib/Opaque.cs (Owned): new property saying whether or not gtk#
	owns the memory.
	(Opaque): Set Owned to true in the void ctor and false in the
	IntPtr one.
	(GetOpaque): add a new overload that can also create opaques, a la
	GLib.Object.GetObject.
	(Ref, Unref, Free): empty virtual methods to be overridden by
	subclasses.
	(set_Raw): Unref() and possibly Free() the old value, Ref() the
	new one.
	(~Opaque, Dispose): set Raw to IntPtr.Zero (triggering Free/Unref
	if needed)

	* parser/gapi2xml.pl (addReturnElem): if the method is named Copy
	and returns a pointer, set the "owned" attribute on the
	return-type.

	* */*-api.raw: Regen
	
	* generator/HandleBase.cs (FromNative): Add new
	FromNative/FromNativeReturn overloads that takes a "bool owned"
	param. Implement the 1-arg FromNative and FromNativeReturn in
	terms of that.

	* generator/ObjectBase.cs (FromNative): Implement HandleBase's new
	overload. Use the two-arg version of GLib.Object.GetObject when
	"owned" is true.

	* generator/OpaqueGen.cs (Generate): Pull out Ref, Unref, and
	Free/Destroy/Dispose methods and handle them specially by
	overriding Opaque.Ref, .Unref, and .Free appropriately. (If any
	of the methods are marked deprecated, output a deprecated
	do-nothing method as well, to save us from having to write all
	those deprecated methods by hand.)
	(FromNative): use GetOpaque, passing "owned".

	* generator/ReturnValue.cs (FromNative): if the value is a
	HandleBase, pass Owned to its FromNative().

	* generator/Parameters.cs (Owned): new property (for use on out
	params)
	(FromNative): Call FromNative() on the generatable, handling Owned
	in the case of HandleBase.

	* generator/ManagedCallString.cs:
	* generator/MethodBody.cs:
	* generator/Signal.cs: use param.FromNative() rather than
	param.Generatable.FromNative(), to get ownership right.

	* */*.metadata: Mark opaque ref/unref/free methods deprecated
	(except where we were hiding them before). Add "owned" attributes
	to return values and out params as needed.

	* pango/AttrIterator.custom (GetFont): work around a
	memory-management oddity of the underlying method.

	* pango/AttrFontDesc.cs (AttrFontDesc): copy the passed-in
	FontDescriptor, since the attribute will assume ownership of it.

	* gtk/TreeView.custom (GetPathAtPos): set the "owned" flag on the
	returned TreePaths.

	* gtk/TargetList.custom: Remove refcounting stuff, which is
	now handled automatically

	* gtk/NodeStore.cs (GetPath): clear the Owned flag on the created
	TreePath so that the underlying structure doesn't get freed when
	the function returns

	* gtkhtml/HTMLStream.custom (Destroy): hide this and then
	reimplement it by hand to keep OpaqueGen from using it in
	Dispose(), since calling it after an HTMLStream.Close() will
	result in a crash.
