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.

Dan Winship 6bf7376094 * parser/gapi2xml.pl (addParamsElem): change the handling of
anonymous function pointer types in method signatures. Before, we
	added a <callback> child to the <parameters> node, but the
	generator just ignored it. Now we add the callback (with a made-up
	name) to the toplevel node, and add an ordinary <param> node
	referencing it to the <parameters> node. Also, if the last param
	of the callback is a gpointer, rename it from "arg#" to "data" so
	it will be treated correctly (as the user data passed from the
	calling method). [Fixes #66241]

	* art/art-api.raw: 
	* gdk/gdk-api-2.4.raw: 
	* gdk/gdk-api-2.6.raw: Regen

	* generator/Parameters.cs (IsHidden): loosen the definition of
	hideable user_data; it doesn't have to occur at the end of the
	parameter list, as long as there's a callback arg before it.

	* generator/MethodBody.cs (GetCallString): Use Parameters.IsHidden
	to decide whether or not to squash user_data params, rather than
	trying to duplicate its logic. As a side effect, this also causes
	a handful of methods that take non-hidden IntPtr arguments to
	start actually passing those arguments to C rather than always
	passing IntPtr.Zero.

	* generator/Method.cs (Equals, GetHashCode): Remove unnecessary
	and possibly erroneous hashing overrides.

	* gtk/Gtk.metadata: Hide Gtk.Container.ForeachFull, since it's
	useless and wasn't in gtk# 1.0

	* gtk/Menu.custom (Popup):
	* gtk/TextIter.custom (ForwardFindChar, BackwardFindChar):
	* gnome/App.custom (CreateMenusInterp, InsertMenusInterp,
	CreateToolbarInterp):
	* gnome/Client.custom (RequestInteractionInterp):
	* gnome/Popup.custom (MenuDoPopupModal, MenuDoPopup): Add
	[Obsolete] compat overloads for methods that have now lost a
	useless IntPtr.

Dan Winship 40c4db88a4 * parser/gapi2xml.pl: Make the enum value parser do the right
thing with parenthesized values ("FOO = (1 << 2)") and within-type
	aliases ("GTK_ANCHOR_N = GTK_ANCHOR_NORTH"). Make it intentionally
	do the wrong thing with unparsable values (outputting them as-is
	into the api file) so that we are forced to fix them with metadata
	rather than silently getting incorrect values.

	* gdk/gdk-api-2.4.raw: 
	* gdk/gdk-api-2.6.raw (PixdataType): Now recognized as flags,
	not enum

	* gtk/Gtk.metadata: hide the enums ArgFlags and RcTokenType (which
	are not used by any wrapped API, and which formerly contained
	entirely wrong values).

	* gtk/gtk-api-2.4.raw: 
	* gtk/gtk-api-2.6.raw (AnchorType, SelectionMode): update with
	values for aliases

	* gnome/Gnome.metadata: fix value of Gnome.PrintButtons.Cancel

	* gnome/gnome-api.raw (PrintUnitBase, PaperSelectorFlags,
	PrintDialogFlags, PrintDialogRangeFlags): Now recognized as flags,
	with values.

* bootstrap :
	* bootstrap-2.4 : use ln instead of cp for api files so reparsing
	causes rebuilds.
	* sources/gtk-sharp-2.6-sources.xml : moved from gtk-sharp-sources.xml
	plus fixed the pango, atk, and gdk raw filenames.
	* sources/gtk-sharp-2.4-sources.xml : sources file for 2.4 api.
	* sources/Makefile.am : added 2.4/2.6 targets for api and get-source
	with make api/get-source-code getting/parsing both versions.
	* */*.raw : regenerate
