[glibmm] Implement Gio::Socket ctors using Gio::Initable

[Daniel Elstner <daniel src gnome org>]

commit a8154e320e5da74564c7f068baeea2c1ab03f949
Author: Daniel Elstner <danielk openismus com>
Date:   Tue Sep 8 18:03:41 2009 +0200

    Implement Gio::Socket ctors using Gio::Initable
    
    * gio/src/gio_vfuncs.defs: Add GInitableClass::init() vfunc.
    * gio/src/initable.{ccg,hg} (Initable::init): Use _WRAP_METHOD().
    (Initable::init_vfunc): Wrap GInitableClass::init() vfunc.
    * gio/src/socket.{ccg,hg} (Socket::Socket): Wrap constructors
    manually.  Call Initable::init() from the constructor body.
    (Socket::create), (Socket::create_from_fd): Forward to constructors.
    * tools/m4/convert_gio.m4: Add conversion from GCancellable* to
    const Glib::RefPtr<Cancellable>&.
