[PATCH 0/5] MR5204: DbgHelp and debug info lookup (Part I)

[eric pouech (＠epo)]

This is the first part of a larger serie to cover module loading and debug
info file lookup in dbghelp.
This first part covers:
- a bunch of new tests
- ensuring correct behavior of native some errors pointed out by tests
  (64 bit modules can be loaded on 32 bit programs, and whether the
   fullpath is used in some API).
