Subject: [PATCH 1/2] WIP CI support for Cygwin.

XXX Doesn't get all the way through yet...

XXX Needs some --with-X options

XXX This should use a canned Docker image with all the right packages
installed

XXX We would never want this to run by default in CI, but it'd be nice
to be able to ask for it with ci-os-only!  (See commented out line)

XXX configure is soooo slooow, can we cache it?!  Compiling is also
insanely slow, but ccache gets it down to a couple of minutes if you're
lucky

XXX I don't know how to put variables like BUILD_JOBS into the scripts

XXX I have no idea if crash dump works, and if this should share
elements with the msys work in commitfest #3575
