dirmngr: Use sks-keyservers CA by default for the hkps pool.
* dirmngr/Makefile.am (dist_pkgdata_DATA): Add sks-keyservers.netCA.pem.
* dirmngr/http.c (http_session_new): Add optional arg
intended_hostname and set a default cert.
* dirmngr/ks-engine-hkp.c (send_request): Pass httphost to
http_session_new.

Ship the certificate for the sks-keyservers hkps pool.  If the user
has specified that they want to use
hkps://hkps.pool.sks-keyservers.net, and they have not specified any
hkp-cacert explicitly, then initialize the trust path with this
specific trust anchor.

dirmngr: Add option --use-tor as a stub.
* dirmngr/dirmngr.h (opt): Add field "use_tor".
* dirmngr/dirmngr.c (oUseTor): New.
(opts): Add --use-tor.
(parse_rereadable_options): Set option.
(main): Tell gpgconf about that option.

* dirmngr/crlfetch.c (crl_fetch): Pass TOR flag to the http module and
return an error if LDAP is used in TOR mode.
(ca_cert_fetch): Return an error in TOR mode.
(start_cert_fetch): Ditto.
* dirmngr/ks-engine-finger.c (ks_finger_fetch): Pass TOR flag to the
http module.

* dirmngr/ks-engine-http.c (ks_http_fetch): Ditto.
* dirmngr/ks-engine-ldap.c (ks_ldap_get): Return an error in TOR mode.
(ks_ldap_search): Ditto.
(ks_ldap_put): Ditto.
* dirmngr/ocsp.c (do_ocsp_request): Ditto.  Also pass TOR flag to the
http module.

* dirmngr/server.c (option_handler): Add "honor-keyserver-url-used".
(cmd_dns_cert): Return an error in TOR mode.
(cmd_getinfo): Add subcommand "tor"
* tools/gpgconf-comp.c (gc_options_dirmngr): Add TOR group.
--

More work is required to actually make --use-tor useful.  For now it
returns an error for almost all network access but as soon as we have
added the TOR feature to the http module some parts will start to
work.

84419f42da dirmngr: Support https for KS_FETCH.
* dirmngr/ks-engine-hkp.c (cert_log_cb): Move to ...
* dirmngr/misc.c (cert_log_cb): here.
* dirmngr/ks-engine-http.c (ks_http_fetch): Support 307-redirection
and https.
--

Note that this requires that the root certificates are registered using
the --hkp-cacert option.  Eventually we may introduce a separate
option to allow using different CAs for KS_FETCH and keyserver based
requests.

096e7457ec Change all quotes in strings and comments to the new GNU standard.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems.  We now use two \x27 characters ('...').

The proper solution would be to use the correct Unicode symmetric
quotes here.  However this has the disadvantage that the system
requires Unicode support.  We don't want that today.  If Unicode is
available a generated po file can be used to output proper quotes.  A
simple sed script like the one used for en@quote is sufficient to
change them.

The changes have been done by applying

  sed -i "s/\`\([^'\`]*\)'/'\1'/g"

to most files and fixing obvious problems by hand.  The msgid strings in
the po files were fixed with a similar command.

231d27e0fe Make HKP keyserver engine work again.
We had some debug code here which prevented it from working.
The host selection code still needs a review!

	* ks-engine-http.c (ks_http_help): Do not print help for hkp.
	* ks-engine-hkp.c (ks_hkp_help): Print help only for hkp.
	(send_request): Remove test code.
	(map_host): Use xtrymalloc.

	* certcache.c (classify_pattern): Remove unused variable and make
	explicit substring search work.
