gmmproc: _WRAP_METHOD: Allow multi-word parameter types (unsigned int)

* tools/pm/Function.pm: parse_param(): Allow multi-word parameter types,
as in _WRAP_METHOD(void set_button(unsigned int button = 0),
                   gtk_gesture_single_set_button).
Affects _WRAP_METHOD, _WRAP_SIGNAL, _WRAP_CTOR, _WRAP_CREATE, _WRAP_VFUNC.
Add support for GtkContainer child properties
Rename ambiguously named overridden property variable and type

* glib/glibmm/class.[cc|h]:
* glib/glibmm/interface.cc:
* glib/glibmm/property.cc: Rename properties_quark and properties_type to
iface_properties_quark and iface_properties_type.
As custom_[set|get]_property_callback() in property.cc also sets and gets
user-defined properties, this naming choice may be confusing.
These names are intended for use by glibmm only. Renaming is not an
ABI/API break. Bug #731484.
PropertyBase: Use g_object_notify_by_pspec() instead of g_object_notify()

This approach is faster and recommended by GLib. Bug #731484.
