 Here's a merge candidate for the utls_2 branch. Changes since comment:12:
  * Support for socks5, http, and https proxies. (The same proxy types
 net/http supports.)
  * `utls=none` and `utls=HelloGolang` mean "no uTLS".
  * Copying default `http.Transport` timeouts and other settings.
  * Rudimentary integration tests for the http and https proxies.

 Replying to [comment:13 yawning]:
 > Note that I treat not specifying the argument as "use a sensible
 default", and have `none` special cased as "use the built in TLS stack",
 under the rationale that once the code is solid the only reason to not use
 utls is if something breaks, and "Add `utls=none`" is a easier interim
 workaround to convey to the unwashed masses than "Edit an existing
 argument".

 This sounds like a good design. I think for at least the next release I'll
 leave no `utls` meaning native TLS, and then a future release can
 compatibly upgrade it to mean some sensible uTLS configuration by default.
