8079087: Add support for Cygwin 2.0

[erikj79]

This is a backport of three Cygwin related fixes from jdk8u. In order to better facilitate development in jdk8u-ri, I would like to get these fixes in, so that developers may use recent versions of Cygwin as build environment for this repository. I'm not even sure it's possible to install a pre Cygwin 2.0 environment anymore. All three fixes have been used successfully in jdk8u for years.
