gpg: Fix mailbox based search via AKL keyserver method.
* g10/keyserver.c (keyserver_import_name): Rename to ...
(keyserver_import_mbox): this.  And use mail search mode.
* g10/getkey.c (get_pubkey_byname): Change the two callers.
--

In contrast to a search via keyserver_import_ntds the older
keyserver_import_name used a full match of the provided name despite
that it is only called with an addr-spec (mbox).  Due to the mode the
pattern send to dirmngr was prefixed with a '=' and thus dirmngr used
an exact search;.  This did only work for provided user ids like
"foo@example.org" but not for "<foo@example.org>" or
"Foo <foo@xample.org>".  The old code dates back to 2010.

speedo: Automatically select Authenticode signing cert.

This is required because GlobalSign re-issued the certificate (which
actually required to install InternetExploder in addition to Edge) and
now we have two certs to select from.  The /a option seems to use the
latest generated certificate.

gpg: Lookup a missing public key of the current card via LDAP.

* dirmngr/ks-action.c (ks_action_get): Add arg ldap_only.
* dirmngr/server.c (cmd_ks_get): Add option --ldap.
--

This change makes it easy to start working with gnupg: Just insert the
smartcard or token provided to you and the first time you sign a
message the public key associated with the current card will be
imported and everything is set without any configuration.

This works only with an LDAP directory because it can be expected that
the public key has been put into the LDAP during card personalization.
Of course an LDAP server needs to be configured; in a Windows AD
domain this can be a mere "keyserver ldap:///" in dirmngr.conf.  Other
configured keyservers are ignored.

Requirements for the card driver: The $SIGNKEYID attribute must exists
and a query for the KEY-FPR attribute needs to return the OpenPGP
fingerprint for that key.  This is currently supported for OpenPGP
cards and certain PKCS#15 cards.

* scd/app-help.c (app_help_pubkey_from_cert): New.  Taken from 2.3.

Actually the readkey functions needs to return the uncompressed points
but if there is no readkey function, like in app-p15.c, readcert is
used and here we need to extract and the key and uncompress the point.

Noet that the --advanced flag did not and still does not work if the
key is fetched via readcert.

gpg: Keep temp files when opening images via xdg-open
* g10/photoid.c (get_default_photo_command): Change parameter for

xdg-open spawns the user's preferred image viewer and then exits.
Therefore we must not remove the temp file when it exits,
otherwise by the time the actual image viewer is started the file
doesn't exist any more.
