/** @brief callback function called on definition of a named type in the IDL input file.
 *
 * Generate code for the following IDL construct:
 * @verbatim
   =>   typedef <type-name> <name>;
   @endverbatim
 *
 * This function generates a prototype for the helper function to
 * load the typedef metadata if the typedef is defined
 * within the global scope or the scope of a module.
 * The name of the metadata load function is:
 * @verbatim
        __<scope-elements>_<name>__load
   @endverbatim
 * If the type specification is idl_tbasic a standard mapping will be applied:
 * @verbatim
	typedef <basic-type-mapping> <scope-elements>_<name>;
   @endverbatim
 * If the type specification is a user defined idl_ttypedef, idl_tenum,
 * idl_tstruct or idl_tunion a scoped name mapping will be generated.
 * @verbatim
	<typedef-name> <name>;     => typedef enum <scope-elements>_<typedef-name> <scope-elements>_<name>;
	<enum-name> <name>;        => typedef enum <scope-elements>_<enum-name> <scope-elements>_<name>;
	<struct-name> <name>;      => typedef struct <scope-elements>_<structure-name> <scope-elements>_<name>;
	<union-name> <name>;       => typedef struct <scope-elements>_<union-name> <scope-elements>_<name>;
   @endverbatim
 * If the type specification is idl_tarray then generate a scoped name
 * with the array specifiers:
 * @verbatim
        <other-usertype-name> <name>[n1]..[nn]; =>
            typedef <scope-elements>_<other-usertype-name> <scope-elements>_<name>[n1]..[nn];
        <basic-type> <name>[n1]..[nn];          =>
            typedef <basic-type-mapping> <scope-elements>_<name>[n1]..[nn];
        sequence<spec> <name>[n1]..[nn];        =>
            typedef c_array <scope-elements>_<name>[n1]..[nn];
        sequence<spec,length> <name>[n1]..[nn]; =>
            typedef c_array <scope-elements>_<name>[n1]..[nn];
   @endverbatim
 * If the type specification is idl_tseq then generate a mapping on c_sequence:
 * @verbatim
        sequence<spec> <name>;        => typedef c_sequence <scope-elements>_<name>;
        sequence<spec,length> <name>; => typedef c_sequence <scope-elements>_<name>;
   @endverbatim
 *
 * @param scope Current scope
 * @param name Specifies the name of the type
 * @param defSpec Specifies the type of the named type
