[Mono-list] Detect OS using mono framework

[Jonathan Pryor]

Your OSDetection.IsOSX code can be simplified greatly by using
Mono.Posix.dll in Mono 1.9:

        static bool IsOSX {
                get {
                        if (IsWindows)
                                return false;
                        Mono.Unix.Native.Utsname buf;
                        if (Mono.Unix.Native.Syscall.uname (out buf) ==
                        0) {
                                return string.Compare(buf.sysname, "darwin", true) == 0
                        }
                        return false;
                }
        }
