[PATCH v2] cygwin: define IPTOS_DSCP_VA in netinet/ip.h

[Michał Korczak]

Define IPTOS_DSCP_VA (0xb0) according to RFC 5865 to complete the DSCP
code point definitions in <netinet/ip.h>. This fixes compilation for
utilities like openbsd-netcat.

I provide this patch to the Cygwin sources under the 2-clause BSD license.
