    Cygwin: CI configuration update
    
    Install autoconf and automake, and run winsup/autogen.sh, and don't have
    it silently ignore failures.
    
    On AppVeyor:
    - use latest VM image, to reduce time spent installing updates.
    - run the testsuite, but ignore the result, as some tests don't work
    correctly.
    - hardcode the python-lxml and python-ply packages to install, so we get
    ones for the right python.
    - install texlive collections now needed to build documentation.
    
    On github:
    - Use a copr for cocom, since RPMSphere's package updates don't track
    fedora:latest very efficently.
