          start ref counts at 1 instead of 0 for speed

        * kjs/nodes.cpp:
        (KJS::ParserRefCounted::hasOneRef): Added. Replaces refcount.
        * kjs/nodes.h: Replaced refcount with hasOneRef.

        * wtf/ListRefPtr.h:
        (WTF::ListRefPtr::~ListRefPtr): Changed to use hasOneRef instead of
        refcount, so this class can be used with the RefCounted template.

        * wtf/RefCounted.h:
        (WTF::RefCounted::hasOneRef): Made const, since there's no reason for
        it to be non-const.
