[libvirt] PATCH: Implement virKill for Windows
The addition of virKill to src/util.c breaks Windows build which lacks the
kill() function. Now we technically don't have any code which runs virKill
when built on Windows, but after the 2 weeks holiday I'm very motivated so
wrote a basic implement of virKill() which is a starting point for Win32
in case we need it based on the recommendations in this thread
http://www.nabble.com/kill-signal-td149789.html
Seems Perl does much the same for its kill() implement on Win32 (and is
even more thorough/complete), though we can't just use the Perl code
directly since its GPL licensed. So I've done a minimal stub
