* Notes:
* Functions in this API assume that the supplied dynamic_loader_stream
* object supports the set_file_posn method.

* Procedure dload_module_open

* Effect:
* Reads header information from a dynamic loader module using the specified
* stream object, and returns a handle for the module information. This
* handle may be used in subsequent query calls to obtain information
* contained in the module.
*
* Returns:
* NULL if an error is encountered, otherwise a module handle for use
