* dirmngr/dirmngr-status.h: New. * dirmngr/dirmngr.h: Include dirmngr-status.h and move some prototypes to that file. * dirmngr/t-support.c: New. * dirmngr/Makefile.am (dirmngr_SOURCES): Add dirmngr-status.h. (t_common_src): Add t-support.c. * dirmngr/server.c (dirmngr_status_printf): Bypass if CTRL is NULL. * dirmngr/dns-stuff.c: Include dirmngr-status.h. (libdns_init): Print WARNING status line. Change call callers to take and pass a CTRL argument. * g10/call-dirmngr.c (ks_status_cb): Print info for new WARNING status. -- To test this you can change RESOLV_CONF_NAME in dns-stuff.c and run gpg --recv-key -v SOMETHING.
