Move the DBus classes into a Gio::DBus namespace.

* gio/giomm.h:
* gio/src/dbus*.[hg|ccg]
* gio/src/error.hg: Rename all DBus* classes to remove the prefix, putting
them in a Gio::DBus namespace.
This required the use of the new _GMMPROC_EXTRA_NAMESPACE macro, to avoid
generating a confused wrap_init.cc.
Along the way, I removed unnecessary class predeclarations, instead including
the relevant header, because that is more convenient for users of the API.
* gio/src/dbuserror.[hg|ccg]: Renamed to dbuserrorutils.[hg|ccg] and
renamed the Error namespace to ErrorUtils, to avoid a clash with the
Gio::DBus::Error exception.
* gio/src/filelist.am:
* tools/m4/convert_gio.m4: Changed some conversions.
* examples/dbus/busserver.cc:
* examples/dbus/peer.cc:
* examples/dbus/userbus.cc: Adapted.

This is generally more organized. A prefix, instead of a namespace, looked
generally wrong to C++ coders.
