= util: remove unnecessary reflection in regex

Rather than reflecting on the pattern to get at the `capturingGroupCount` field (which does not exist on android and makes the routes blow up) we take the pattern and do a dummy match against an empty string, getting the `groupCount` from the result.

All the spray-routing tests passed, and trying it out in the console, the new snippet seems to do what I want. It also made my spray-on-android attempt get further in the boot process before blowing up on something else, so it solved my initial problem.

= http: fix Cache-Control directives parser, fixes #862

3 changes:
  - `no-cache = ...` never worked because of ordering of parsing alternatives
  - list of field-names must be quoted completely not per-element
  - allow `token` for `no-cache` / `private` field-names to be more lenient
    even if the httpbis specification says

    "This directive uses the quoted-string form of the argument syntax.  A
     sender SHOULD NOT generate the token form (even if quoting appears
     not to be needed for single-entry lists)."
