Add "gpgconf --kill dirmngr" and avoid useless launch before a kill.

Browse Source 
* common/asshelp.c (start_new_gpg_agent): Add arg autostart.  Change
all callers to use 1 for it.
(start_new_dirmngr): Ditto.
* tools/gpg-connect-agent.c: Add option --no-autostart.
(main): Default autostart to 1.
(start_agent): Implement no-autostart.
* tools/gpgconf-comp.c (gpg_agent_runtime_change): Use --no-autostart.
(scdaemon_runtime_change): Ditto.
(dirmngr_runtime_change): New.
