gpg: Obsolete some keyserver helper options.
* g10/options.h (opt): Remove keyserver_options.other. * g10/gpg.c (main): Obsolete option --honor-http-proxt. * g10/keyserver.c (add_canonical_option): Replace by ... (warn_kshelper_option): New. (parse_keyserver_uri): Obsolete "x-broken-http".
Some of these options are deprecated for 10 years and they do not make
any sense without the keyserver helpers. For one we print a hint on
how to replace it:
gpg: keyserver option 'ca-cert-file' is obsolete; \ please use 'hkp-cacert' in dirmngr.conf
