• switch property lists to be vector+set of Identifiers instead of list of References

This has the following benefits:

• no duplicates in property lists
• simplifies API calls
• probably more efficient, since linked list is gone
• entirely removed Reference, ReferenceList and ProtectedReference types from the API

• kjs/PropertyNameArray.cpp: Added. (KJS::PropertyNameArray::add): Check set, if not already there, add to vector.
• kjs/PropertyNameArray.h: Added. (KJS::PropertyNameArray::PropertyNameArray): Newly added type, combines a set and a vector to make a unique but ordered list of identifiers. (KJS::PropertyNameArray::begin): ditto (KJS::PropertyNameArray::end): ditto (KJS::PropertyNameArray::size): ditto (KJS::PropertyNameArray::operator[]): ditto
• kjs/array_instance.h:
• kjs/array_object.cpp: (ArrayInstance::getPropertyNames): renamed from getPropertyList, updated for PropertyNameArray (ArrayInstance::setLength): updated for PropertyNameArray (ArrayInstance::pushUndefinedObjectsToEnd): ditto
• kjs/nodes.cpp: (ForInNode::execute): updated for PropertyNameArray
• kjs/nodes.h:
• kjs/object.cpp: (KJS::JSObject::getPropertyNames): renamed from getPropertyList, updated for PropertyNameArray
• kjs/object.h:
• kjs/property_map.cpp: (KJS::PropertyMap::getEnumerablePropertyNames): updated for PropertyNameArray (KJS::PropertyMap::getSparseArrayPropertyNames): ditto
• kjs/property_map.h:
• kjs/protected_reference.h: Removed.
• kjs/reference.cpp: Removed.
• kjs/reference.h: Removed.
• kjs/reference_list.cpp: Removed.
• kjs/reference_list.h: Removed.
• kjs/scope_chain.cpp: (KJS::ScopeChain::print): Use PropertyNamesArray instead of ReferenceList.
• kjs/string_object.cpp: (StringInstance::getPropertyNames): Updated for new approach.
• kjs/string_object.h:
• kjs/ustring.h:
• API/APICast.h: (toJS): Added overload for PropertyNameAccumulatorRef / PropertyNameArray* (toRef): ditto
• API/JSBase.h:
• API/JSCallbackObject.cpp: (KJS::JSCallbackObject::getPropertyNames): Fixed for new API.
• API/JSCallbackObject.h:
• API/JSObjectRef.cpp: (JSPropertyNameArray::JSPropertyNameArray): Type used for a publicly vended JSPropertyNameArrayRef. (JSObjectCopyPropertyNames): New API call - renamed / refactored from JSObjectCreatePropertyList (JSPropertyNameArrayRetain): new retain call for JSPropertyNameArray. (JSPropertyNameArrayRelease): new release call for - " -. (JSPropertyNameArrayGetCount): Instead of having to use a stateful enumerator you can now get the count and items in any order. (JSPropertyNameArrayGetNameAtIndex): See above. (JSPropertyNameAccumulatorAddName): What you add properties to is now an opaque accumulator object.
• API/JSObjectRef.h: Prototyped new functions, removed old ones
• JavaScriptCore.exp: Updated exported symbols.
• JavaScriptCore.xcodeproj/project.pbxproj: Added new files, removed old.
• API/testapi.c: (MyObject_getPropertyNames): Renamed / fixed callback to fit new paradigm. (main): Updated for new API.
