* 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. svn path=/trunk/gtk-sharp/; revision=47928
