[PATCH 00/12] Some dbghelp enhancements for gecko support

[Eric Pouech]

Jacek ping'ed me about winedbg/dbghelp not being able to fully support gecko (especially for preparing the 1.2 release).
The following patchset enhance winedbg/dbghelp support:
- proper support for method management in dwarf debug format (now being able to step/break/... on methods
  as one is supposed to do on functions)
- proper C++ namespace support
- fixed some COFF bugs
- performance increase, especially for very large files (gecko being one on them). performance loss on regular files
  is merely perceptible (<+1% from my testing) but give more than 90% speed increase on large files.

A huge thank you to Jacek for his various efforts to test several versions of this patchset.

However, there are still a couple of issues to be fixed on winedbg/dbghelp, especially on stack backtracing.
But let first get this one committed.

A+
