Merge branches 'bp/reset-quiet' and 'js/mingw-http-ssl' into nd/config-split

* bp/reset-quiet:
  reset: warn when refresh_index() takes more than 2 seconds
  reset: add new reset.quiet config setting
  reset: don't compute unstaged changes after reset when --quiet

* js/mingw-http-ssl:
  http: when using Secure Channel, ignore sslCAInfo by default
  http: add support for disabling SSL revocation checks in cURL
  http: add support for selecting SSL backends at runtime
