The POSIX version have been kept intact, the changes intend to move the usages of OS-specific types (ucontext_t and EXECPTION_POINTERS et al) out from utilities/debug.cpp, to keep it os-agnostic, and let OS specific handlers call into it (for disarm and context save (now os specific)).

There are also some simplifications and const-correctness.
