* glib/Object.cs: add support for native instantiation of
managed types.
* glib/ParamSpec.cs: add Flags ctor overload.
* sample/NativeInstantiationTest.cs: new sample to test the
unmanaged instantiation capability.
Based on a patch from Sebastian Dröge [Fixes#499900]

* 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.

* 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.
