* common/http.c (send_request, connect_server, http_open): Use a
struct srv instead of a single srvtag so we can pass the chosen host
and port back to the caller.
(connect_server): Use the proper port in the HAVE_GETADDRINFO case.
* keyserver/curl-shim.c (curl_easy_perform): Use struct srv and log
chosen host and port.
* keyserver/gpgkeys_hkp.c (main): Properly take the port given by SRV.
Backported from ba9e974f1f
a CURLOPT_SRVTAG_GPG_HACK (passed through the the http engine).
* http.h: Allow passing srvtag to http_open and http_open_document.
* http.c (http_open, http_open_document): Allow passing srvtag to
http_open and http_open_document.

* curl-shim.h, curl-shim.c (curl_free): Make into a macro.
(curl_version_info): New. Only advertises "http" for our shim, of
course.
protocols we handle. Directly pass them to curl or fake-curl and see if
an error comes back.
* curl-shim.h, curl-shim.c (handle_error), ksutil.c (curl_err_to_gpg_err):
Add support for CURLE_UNSUPPORTED_PROTOCOL in fake curl.
* Makefile.am: Don't need -DFAKE_CURL any longer since it's in config.h.

* gpgkeys_http.c: Don't need to define HTTP_PROXY_ENV here since it's
in ksutil.h.
* gpgkeys_curl.c (get_key, main), gpgkeys_hkp.c (main): Pass AUTH
values to curl or curl-shim.
* curl-shim.c (curl_easy_perform), gpgkeys_curl.c (main),
gpgkeys_hkp.c (main): Use curl-style proxy semantics.
