[PATCH 00/10] Seventh step (and last to date) for Dwarf 3/4 support in dbghelp

[Eric Pouech]

The following series implements:
- better support for some compilation units descriptions
- DW_OP_call_frame_cfa implementation: gcc when emitting dwarf4, heavily
  uses this for describing vars/parameters.
- silencing some unsupported yet elements
- now letting dbghelp, **by default**, load compilations unit with
  dwarf 2, 3 or 4 debug information
- by option, let wine be compiled with dwarf4 debug information (default is
  still dwarf 2)

A+
