Implemented optional properties.
* objc-act.h (PROPERTY_OPTIONAL): New.
* objc-act.c (objc_add_property_declaration): Set
PROPERTY_OPTIONAL if appropriate.
(finish_class): When generating definitions of setter and getter
methods associated with a property for a protocol, mark them as
optional if the property is optional.
(maybe_make_artificial_property_decl): Added 'getter_name'
argument. Set PROPERTY_OPTIONAL.
(objc_maybe_build_component_ref): Updated calls to
maybe_make_artificial_property_decl. Added code for optional,
readonly properties.
(objc_build_class_component_ref): Updated call to
maybe_make_artificial_property_decl.
