dirmngr: Support pseudo URI scheme "opaque".

* dirmngr/http.h (HTTP_PARSE_NO_SCHEME_CHECK): New.
* dirmngr/http.c (http_parse_uri): Use this flag.  Change all callers
to use the new macro for better readability.
(do_parse_uri): Add pseudo scheme "opaque".
(uri_query_value): New.

This scheme can be used to convey arbitrary strings in a parsed_uri_t
object.
