Restrict the name used in %extend to be just the struct/class name and not a typedef to a class/struct. Typedefs were only partially working anyway. Anonymous struct typedefs excluded. Deprecate with a warning for now.

 ============================
 
+2013-02-15: wsfulton
+            Deprecate typedef names used in %extend that are not the real class/struct name. For example:
+
+              typedef struct StructBName {
+                int myint;
+              } StructB;
+
+              %extend StructB {
+                void method() {}
+              }
+
+            will now trigger a warning:
+
+              swig_extend.i:19: Warning 326: Deprecated %extend name used - the struct name StructBName
+              should be used instead of the typedef name StructB.
+
+            This is only partially working anyway (the %extend only worked if placed after the class
+            definition).
