Ilya Berezhniuk updated HARMONY-5590:
-------------------------------------

    Attachment: 0002-Move-signal-and-crash-handling-to-the-Port-to-be-use.patch
                0001-move-Moving-to-PORT-memory-access-stack-dump.patch

I've moved signal and crash handling to the Port onto the new signal/crash handling interfaces.
Additionally this included:
- moving memory access functions and breakpoints instrumentation to the Port;
- moving native stack unwinding to the Port;
- moving mutex implementation from the Hythread to the Port;

The patches suggested were build over r634360; pre-commit tests are passed on Windows/Linux x86/x86_64, and Linux/ia64/interpreter.

Known problems:
1) these patches should be merged with latest canges, specifically with r634547 and r634569
2) crash stack now contains native functions only; Java unwinding VM callback is not implemented yet
3) to work properly, the Port should become shared library (to avoid static vars duplication etc.)

I'm going to perform tasks 1) - 3) soon, then I'll update the patches.
