What seemed to be a race condition (because of not happenning 100% of
the times) ended up being an early garbage collection of a delegate that
was still referenced by an unmanaged struct without having a managed
counterpart [1].
The consequence of this was a NullReferenceException happening in a line
which didn't have a dereference of a null object. The way to reproduce it
deterministically 100% of the times was setting the env var MONO_NO_SMP.

GObject upstream has started disabling support for installing interfaces
in GTypes after they have already been initialized (class_init) [1], so
we need to add GInterfaces a bit earlier (*before* class_init starts).
As GLib.Object.OverrideProperty() cannot to be called before class_init
(because it receives a GObjectClass, not a GType) or after (because
otherwise class_init would complain about properties of an interface not
being defined), then we need to call it during class_init.

A good side-effect of this fix is that we no longer use the hacky uint
field 'idx' to track the properties count for each class; now it gets
moved to the ClassInitializer class, and thus can be non-static, which
makes a bit more sense (we leave the old OverrideProperty overload for
backwards compatibility).
Simplest way to test this is launching the sample/treemodeldemo.exe and
sample/custom-scrollable.exe in Ubuntu 13.04 beta (which has GLib 2.36).

* glib/Value.cs:
mark private struct fields public to avoid 0169, and remove the nowarn
from the csc command. fixed one real warning, exposed a bunch of
obsolete usage still to fix.
* glib/Global.cs: Kill the calling convention field again.
It breaks GLib 2.x compatibility in the generator and there is
probably no need to make the calling convention configurable.
* .cs, *.custom: Hardcode Cdecl calling convention instead of
using GLib's field.
svn path=/trunk/gtk-sharp/; revision=141283
* glib/Global.cs: Add a public constant field specifying the
calling convention used by GLib and depending libraries.
By now it's hardcoded to Cdecl as every non-Win32 runtime
should ignore this attribute.
* *.cs, *.custom: Use GLib.Global.CallingConvention for both
pinvokes and callbacks. Plugs a stack leak on Win32. All
pinvokes defaulted to StdCall and thus the stack was never
cleaned up.

* configure.in.in: add new dir and autofu for it.
* Makefile.am: add new dir
* gapi/*: a small extension method library to add generation-related
api to GType in 2.0. Access it with -pkg:gapi-2.0-compat to pick up
the needed refs.
* generator/GObjectVM.cs: generate new GType getter methods.
* generator/ObjectGen.cs: generate new GType getter methods.
* glib/GType.cs: change a few props to methods to make them extension
method friendly for 2.0 compat.
* glib/Object.cs: use new GType getter methods.
* glib/Value.cs: use new GType getter methods.
* gtk/Widget.custom: use new GetClassPtr method.
svn path=/trunk/gtk-sharp/; revision=139609
* glib/GType.cs: lock the types hash to support threaded access and
type registration. Apparently gtype access/registration is threadsafe
in glib. [Fixes#526229]
svn path=/trunk/gtk-sharp/; revision=139247
* glib/GType.cs: add ResolveType event and TypeResolutionHandler delegate
declarations. This mechanism supports the lazy registration of type mappings
by bindings. Patch from Sebastian with minor naming tweek. [Fixes#497667]
svn path=/trunk/gtk-sharp/; revision=137759
Add support for virtual methods(vm) to the generator.
* parser/gapi2xml.pl: Generate a class_struct element with
all members of the class structure. Dump the first (instance)
parameter for signal and vm elements. Bump up parser version.
* generator/GObjectVM.cs: Added. Support for GObject virtual methods.
* generator/DefaultSignalHandler.cs: Signal specific part of vm
generation.
* generator/InterfaceVM.cs: New class for interface vms.
* generator/ObjectBase.cs: Parse the class struct.
svn path=/trunk/gtk-sharp/; revision=131604
* GType.cs: convert GType.Is to a non-static function.
* Value.cs: track API.
[Last cosmetic bit from #448009]
svn path=/trunk/gtk-sharp/; revision=122505
* generator/InterfaceGen.cs: use the new GLib API to detect
instances that don't implement GInterfaces.
* glib/GType.cs: add new API for checking if an IntPtr instance
implements a certain GType.
[Fixes#448009]
svn path=/trunk/gtk-sharp/; revision=121990
* glib/GType.cs: kill the FindTypeInReferences recursive loading
algorithm and instead do a name-based search through the references
of loaded assemblies only. Fixes the original bug #400595 and it
hopefully will have fewer sideeffects that the recursive loading
approach.
svn path=/trunk/gtk-sharp/; revision=114008
* glib/GType.cs: just fail on location null or empty instead of
checking the assembly type. Avoids failures on the ms runtime.
svn path=/trunk/gtk-sharp/; revision=113989
* glib/GType.cs (FindTypeInReferences): Put a try-catch around the assembly
loading as failure to load a referenced assembly is not really an error.
svn path=/trunk/gtk-sharp/; revision=112905
* glib/GType.cs: beef up the referenced assembly loading code to
handle assemblies located in the same directory as the referring
assembly. Fixes#423450.
svn path=/trunk/gtk-sharp/; revision=112545
* glib/Signal.cs: AddEmissionHook binding (for closing #386950), and
change API of Emit to mimic the detailed_signal pattern.
* glib/GType.cs: GType.FromName: new wrapper for native call.
* glib/ObjectManager.cs: Use the new FromName managed method.
svn path=/trunk/gtk-sharp/; revision=103198
* */*-api.xml: Regen, adding gtype="..." to many enum types
* generator/EnumGen.cs (Generate): if the enum has the
"gtype" property, add a GTypeAttribute pointing to an internal
FooGType class whose GType property can be used to get the enum's
GType.
* generator/ObjectGen.cs:
s/ObjectManager.RegisterType/GType.Register/
* glib/GTypeAttribute.cs: attribute for indicating a property that
will return the GType of a type (particularly for enums, which
can't have GType properties added to them).
* glib/GType.cs: renamed from Type.cs to match the type name
(public static readonly GType ...): add a few missing types.
(Register): moved from ObjectManager.RegisterType
(LookupGType): moved from TypeConverter.LookupType and extended to
handle GTypeAttribute. Also, fix mappings for sbyte/byte/char, and
return specific GTypes for Object subclasses rather than always
returning GType.Object. [Fixes#74699]
(LookupType): moved from ObjectWrapper.LookupType
(ToString): return the type name
* glib/Object.cs (RegisterGType):
s/ObjectManager.Register/GType.Register/
(LookupGType): Make this protected internal so GType can access
it.
* glib/ObjectManager.cs (RegisterType): deprecate in favor of
GType.Register.
(LookupType): moved to GType
* glib/TypeConverter.cs (LookupType): now a deprecated wrapper
around GType.LookupGType.
* glib/Value.cs: Use GType casts rather than TypeConverter
* gtk/NodeStore.cs (ScanType):
* gtk/ListStore.custom (ListStore):
* gtk/TreeStore.custom (TreeStore): Use (GType) cast rather than
TypeConverter. Remove the error check and exception, since the
cast never returns GType.Invalid. (The check probably predates
GLib.ManagedValue.)
* gnome/PanelAppletFactory.cs (Register): Use a GType cast rather
than GLib.Object.LookupGType (which is no longer accessible after
an mcs bugfix)
* sample/GtkDemo/DemoIconView.cs (CreateStore): use the Type[]
constructor rather than the GType[] constructor, since it
translates typeof(Gdk.Pixbuf) correctly now.
