to be signed (when exporting) or authenticated (when importing).  Now,
we spawn it once for all and then follow a request/reply protocol.  This
reduces the wall-clock time of:

  guix archive --export -r $(guix build coreutils -d)

from 30s to 2s.

* guix/scripts/authenticate.scm (sign-with-key): Return the signature
instead of displaying it.  Raise a &amp;formatted-message instead of calling
'leave'.
(validate-signature): Likewise.
(read-command): New procedure.
(define-enumerate-type, reply-code): New macros.
(guix-authenticate)[send-reply]: New procedure.
Change to read commands from current-input-port.
* nix/libstore/local-store.cc (runAuthenticationProgram): Remove.
(authenticationAgent, readInteger, readAuthenticateReply): New
functions.
(signHash, verifySignature): Rewrite in terms of the agent.
* tests/store.scm ("import not signed"): Remove 'pk' call.
("import signed by unauthorized key"): Check the error message of C.
* tests/guix-authenticate.sh: Rewrite using the new protocol.
