tools: New option --keyboxd for gpg-connect-agent.

* configure.ac: New option --keyboxd-pgm.
(KEYBOXD_NAME, KEYBOXD_DISP_NAME): New ac_defines.
* common/util.h: Add substitutes for new error codes.
(GNUPG_MODULE_NAME_KEYBOXD): New.
* common/homedir.c (gnupg_module_name): Support
GNUPG_MODULE_NAME_KEYBOXD.
* common/asshelp.c (SECS_TO_WAIT_FOR_KEYBOXD): New.
(wait_for_sock): Support keyboxd.
(start_new_service): Ditto.
(start_new_keyboxd): New.
* tools/gpg-connect-agent.c: New options --keyboxd and
--keyboxd-program.
(start_agent): Implement new option.
--

This change allows us to test the new keyboxd using our standard
helper.  It also provides the necessary code to start keyboxd on the
fly.
