P/Invoke wrapper for goproxy

GoProxy wrapper

This is go proxy wrapped for .NET 2.0. Repo contains golang part and c# part.

• .NET MS Visual Studio debugger conflicts with GO Crash Handler. So in order to work it normally you have to apply a small patch to go runtime. In file c:\Go\src\runtime\signal_windows.go, line 154 or whatever path you have add

// lastcontinuehandler is reached, because runtime cannot handle
// current exception. lastcontinuehandler will print crash info and exit.
//
// It is nosplit for the same reason as exceptionhandler.
//
//go:nosplit
func lastcontinuehandler(info *exceptionrecord, r *context, gp *g) int32 {
   if testingWER {
   	return _EXCEPTION_CONTINUE_SEARCH
   }

   return _EXCEPTION_CONTINUE_SEARCH //this is new line. We had to pass all of this to .NET handler so debugging would work in MSVS
