[PATCH] [Support] Lazy load of dbghlp.dll on Windows

[Leny Kholodov]

The additional issue with automatic DLL delay loading is error handling. By default, application will fail in case of DLL absense, if there are no hooks or SEH handlers (https://msdn.microsoft.com/en-us/library/3aeywt27.aspx). So for automatic delay-loaded DLLs we have to write such hooks/handlers. Manual loading aproach doesn't have such drawback.
