Description
WindbgDebuggerLocal (src/jdk.hotspot.agent/windows/native/libsaproc/sawindbg.cpp) needs some improvements:
- need to report COM error codes (this helps investigate failures like JDK-8204994, JDK-8230731, JDK-8001227);
- SAOutputCallbacks IUnknown implementation (AddRef, Release) are not thread-safe;
- fix int/size_t usage(for example in SAOutputCallbacks::Output)
