1. Support unprivileged symlink creation in Windows …

   Symlink creation on Windows has in the past basically required admin;
   it’s being opened up a bit in the Creators Update, so that at least
   people who have put their computers into Developer Mode will be able to
   create symlinks without special privileges. (Microsoft are being
   cautious about it all; the Developer Mode requirement makes it so that
   it this won’t be as helpful as I’d like, but it’s still an improvement
   over requiring admin.)
   
   Because of compatibility concerns, they’ve hidden this new functionality
   behind a new flag in the CreateSymbolicLink dwFlags:
   SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE. So we add this flag in
   order to join the party.
   
   Older Windows doesn’t like this new flag, though, so if we encounter
   ERROR_INVALID_PARAMETER we try again without the new flag.

     that Developer Mode will still be required.
