gpg: Refresh expired keys originating from the WKD.

(get_pubkey_byname): Set it.
(only_expired_enc_subkeys): New.
(get_best_pubkey_byname): Add support to refresh expired keys from the

--

A little drawback of that code is that if the WKD has no update for an
expired key each access of the key will trigger a WKD lookup (unless
cached by the dirmngr).  To avoid this we need to record the last time
we have checked for an update but that would in turn require that we
update the keyring for each check.  We defer this until we have a
better key database which allows for fast updates of meta data.

Testing the code is currently a bit cumbersome because it requires to
update a key in the WKD several times.  Eventually we we need a
network emulation layer to provide sample data for the regression
tests.

--

This is a first try on a protocol to pair two devices so that they can
agree on a shared secret to exchange secret keys.  The idea is that if
you want to sync your secret keys to another machine (e.g. from
desktop to mobile) you have physical access to both devices and thus a
pairing protocol allows to authenitcate the connection using a short
string.  See the source for a protocol description.

How to test:

  $ gpg-pair-tool -va --homedir . --initiate >msg.commit
  $ gpg-pair-tool -va --homedir 2ndhome --respond  \
                                        <msg.commit >msg.dhpart1
  $ gpg-pair-tool -va --homedir . --respond \
                                        <msg.dhpart1 >msg.dhpart2
  $ gpg-pair-tool -va --homedir 2ndhome --respond \
                                        <msg.dhpart2 >msg.confirm

Now set the SAS as printed by the responder into SAS and run

  $ gpg-pair-tool -va --homedir . --respond --sas $SAS <msg.confirm

Storing the secret on disk is obviously not the right thing to do.
With the new PUT_SECRET and GET_SECRET commands of gpg-agent we can
change this to store it all in gpg-agent instead.  This will make it
also easier for gpg to access the secret and we won't need an option
to return it from gpg-pair-tool.  Thus gpg-pair-tool can be dedicated
to run the protocol and maybe to popup info dialogs.

Adding a second expiration time for running the protocol in addition
to the expiration of the secret is probably a better idea than just
that simple catch-all TTL.

There is no good reason to bind local port aggressively.  It might be
some reason to do so, then, a user can specify it in /etc/resolv.conf
by the second argument of "interface" directive.

At least, it causes a problem on Windows.  Binding a specified port in
user space can trigger the Firewall dialog on Windows.  Since it can
be considered valid question, it is better not to bind with an
ephemeral port which is selected in user space, by default.

wks: Take name of sendmail from configure.
* configure.ac (NAME_OF_SENDMAIL): New ac_define.
* tools/send-mail.c (run_sendmail): Use it.

We used to ac_subst the SENDMAIL in the old keyserver via mail script.
We cab reuse this to avoid a fixed name for sendmail in the
send-mail.c helper.
