        Fix <rdar://problem/5092653>
        REGRESSION: Image decoding making scrolling slow
        
        If decoder gave back a null frame (which I think happens regularly if you don't have full frame 
        data yet for image that does not decode incrementally) m_decodedSize was incremented anyway. This
        led to massive growth in calculated image size and eventually made cache prune constantly. 
        
        No test, I don't know how to make one for this.

        Fix for: http://bugs.webkit.org/show_bug.cgi?id=13142

        The previous fix http://bugs.webkit.org/show_bug.cgi?id=12636 
        introduced new JNIType to enum in jni_utility.h This is a 
        problem on the Mac as it seems that the JNIType enum is also
        used in the JVM, it is used to specify the return type in
        jni_objc.mm
        Corrected the fix by moving type to the end, and changing
        jni_objc.mm to convert the new type to an old compatible
        type.

        Since CFTypeRef is really void*, a RetainPtr couldn't be used. 
        RefType was "void", which doesn't actually exist as a type.
        Since RefType only existed for operator*(), and since that operator
        doesn't make any sense for RetainPtr, I removed them!

        * kjs/nodes.cpp: Touch this to force a rebuild and (hopefully) help the
          compiler with dependencies
        * wtf/RetainPtr.h: Nuke RefType and operator*()
