[PATCH 0/4] MR5256: DbgHelp and debug info lookup (Part IV)

[eric pouech (＠epo)]

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

- support for SLMFLAG_NO_SYMBOLS flag in SymLoadModule
- PDB related values in module information now match what native returns

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.
At the end of the serie, all the todo:s are now resolved.
