module extension: add support for canonical name resolution (#2013)

Browse Source 
Before attempting to load a module, each provided resolver must be given an
opportunity to examine the name of the requested module without actually
loading it so as to canonicalize it, in case a module can be referred to by
multiple names.

Then, modules are loaded and cached by their canonical name.
