Windows Appveyor build

* builds Windows wheels against a specified libyaml repo/refspec for many Python versions
* since we don't have multiple Appveyor workers, it's faster/more convenient to run them serially
* not all paths sufficient for general CI usage yet; still needs manual inspection/testing of output
* various hacks to quiet warning noise during build on old Pythons
