Log:
[KDVBOX]
Implement a virtualkd compatible kernel debugger transport DLL. I started this, because I
didn't manage to get the original one working, but it turned out, the original one
works, you only need to use the correct virtualkd version. Anyway, it's there now. A
virtualkd version that works with VBox 4.3.16+ can be found here:
http://forum.sysprogs.com/viewtopic.php?f=4&t=3370 or here:
http://public.avast.com/~hnanicek/VirtualKd.zip
The folder is called kdvm, since I thought about adding support for VMWare as well, but
here the original one probably works as well.
Also fix my email address in some files.
