- added size information about most of the generated thunks (import,
16/32 relay...)
- marked the wine thunks by inserting specific symbols (to be managed
by wine's dbghelp)
- removed the stabs generation:
+ mostly used by winedbg, and the previous item will replace it for
dbghelp
+ still broken for gdb anyway
- enhanced const correctness
