[PATCH 0/5] MR5233: Dbghelp and debug info lookup (Part II)

[eric pouech (＠epo)]

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

- new tests about SymLoadModule flags and options
- separating PDB file loading from trying to find the PDB file matching
  the requested lookup parameter

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.
