Add support for using raw public keys in TLS (RFC 7250)

Since GnuTLS removed support for OpenPGP keys in TLS (RFC 6091), and
no other library supports it, we have to change the protocol to use
something else.  We choose to use "raw public keys" (RFC 7250).  Since
we still use OpenPGP keys to decrypt the secret password, this means
that each client will have two keys: One OpenPGP key and one TLS
public/private key, and the key ID of the latter key is used to
identify clients instead of the fingerprint of the OpenPGP key.

Note that this code is still compatible with GnuTLS before version
3.6.0 (when OpenPGP key support was removed).  This commit merely adds
support for using raw pulic keys instead with GnuTLS 3.6.6. or later.

* DBUS-API (Signals/ClientNotFound): Change name of first parameter
                                     from "Fingerprint" to "KeyID".
  (Mandos Client Interface/Properties/KeyID): New.
* INSTALL: Document conflict with GnuTLS 3.6.0 (which removed OpenPGP
           key support) up until 3.6.6, when support for raw public
           keys was added.  Also document new dependency of client on
           "gnutls-bin" package (for certtool).
* Makefile (run-client): Depend on TLS key files, and also pass them
                         as arguments to client.
  (keydir/tls-privkey.pem, keydir/tls-pubkey.pem): New.
  (confdir/clients.conf): Add dependency on TLS public key.
  (purge-client): Add removal of TLS key files.
* clients.conf ([foo]/key_id, [bar]/key_id): New.
* debian/control (Source: mandos/Build-Depends): Also allow
                                                 libgnutls30 (>= 3.6.6)
  (Package: mandos/Depends): - '' -
  (Package: mandos/Description): Alter description to match new
                                 design.
  (Package: mandos-client/Description): - '' -
  (Package: mandos-client/Depends): Move "gnutls-bin | openssl" to

* debian/mandos-client.README.Debian: Add --tls-privkey and
                                      --tls-pubkey options to test
                                      command.
* debian/mandos-client.postinst (create_key): Renamed to "create_keys"
                                             (all callers changed),
                                             and also create TLS key.
* debian/mandos-client.postrm (purge): Also remove TLS key files.
* intro.xml (DESCRIPTION): Describe new dual-key design.
* mandos (GnuTLS): Define different functions depending on whether
                   support for raw public keys is detected.
  (Client.key_id): New attribute.
  (ClientDBus.KeyID_dbus_property): New method.
  (ProxyClient.__init__): Take new "key_id" parameter.
  (ClientHandler.handle): Use key IDs when using raw public keys and
                          use fingerprints when using OpenPGP keys.
  (ClientHandler.peer_certificate): Also handle raw public keys.
  (ClientHandler.key_id): New.
  (MandosServer.handle_ipc): Pass key ID over the pipe IPC.  Also
                             check for key ID matches when looking up
                             clients.
  (main): Default GnuTLS priority string depends on whether we are
          using raw public keys or not.  When unpickling clients, set
          key_id if not set in the pickle.
  (main/MandosDBusService.ClientNotFound): Change name of first
                                           parameter from
                                           "Fingerprint" to "KeyID".
* mandos-clients.conf.xml (OPTIONS): Document new "key_id" option.
  (OPTIONS/secret): Mention new key ID matchning.
  (EXPANSION/RUNTIME EXPANSION): Add new "key_id" option.

                                 when using raw public keys.
* mandos.xml (NETWORK PROTOCOL): Describe new protocol using key ID.
  (BUGS): Remove issue about checking expire times of OpenPGP keys,
          since TLS public keys do not have expiration times.
  (SECURITY/CLIENT): Alter description to match new design.
  (SEE ALSO/GnuTLS): - '' -
  (SEE ALSO): Add reference to RFC 7250, and alter description of when

                             parameters (based on size of OpenPGP key)
                             when using OpenPGP in TLS.  Default
                             GnuTLS priority string depends on whether
                             we are using raw public keys or not.
