[PATCH 0/5] MR5248: DbgHelp and debug info lookup (Part III)

[eric pouech (＠epo)]

This is the third part of a larger serie of four parts to cover module loading
and debug info file lookup in dbghelp. This third part covers:

- searching some sub directories of search-path elements
- better support of various forms of module name
- change the order of module lookup (improves performance in some games)
- various corner case fixes

Note: some modifications require new todo marks in the tests, as the full fix
will require changing other areas that would make the change too large.
The large serie of four parts resolves all the todo:s.
