* certchain.c (gpgsm_validate_chain) <gpgsm_cert_use_cer_p>: Do
not just warn if a cert is not suitable; bail out immediately.
* call-dirmngr.c (isvalid_status_cb): New.
(unhexify_fpr): New. Taken from ../g10/call-agent.c
(gpgsm_dirmngr_isvalid): Add new arg CTRL, changed caller to pass
it thru. Detect need to check the respondert cert and do that.
* certchain.c (gpgsm_validate_chain): Add new arg FLAGS. Changed
all callers.
* gpgconf-comp.c (gc_options_dirmngr): Set GC_OPT_FLAG_ARG_OPT for
"LDAP Server".
(change_options_file): Remove assertion that tests that this flag
is not present. Handle an empty string in OPTION->new_value.
* g10.c: New options --gpgconf-list, --debug-level and --log-file
(set_debug): Add arg DEBUG_LEVEL.
(main): Look at less and less version specific config files. From
gnupg 1.3.
* gpgconf-comp.c: Include <signal.h>.
(gc_backend): Add new member runtime_change.
(gpg_agent_runtime_change): New function.
(gc_component_change_options): New variable runtime. Initialize
it. If an option is changed that has the GC_OPT_FLAG_RUNTIME bit
set, also set the corresponding runtime variable. Finally, call
the runtime_change callback of the backend if needed.
* app-nks.c (get_length_of_cert): Removed.
* app-help.c: New.
(app_help_read_length_of_cert): New. Code taken from above. New
optional arg R_CERTOFF.
* card-dinsig.c: Removed.
* card.c (card_get_serial_and_stamp): Do not bind to the old and
never finsiged card-dinsig.c.
* iso7816.c (iso7816_read_binary): Allow for an NMAX > 254.
* gpgconf-comp.c (gc_component_change_options): Set the filenames
of the option's backend, not of the component.
Also use GC_BACKEND_NR, not GC_COMPONENT_NR.
* README.gpgconf (NAME): Add info about optional arg and arg type 0.
* gpgconf-comp.c (gc_component_change_options): Parse list of
arg type 0 options.
(option_check_validity): Add new argument NEW_VALUE_NR. Perform
rigorous validity checks.
(change_options_program): Disable an option also if we have a new
value for it.
* gpgconf-comp.c (struct gc_option): Add new member new_flags.
(option_check_validity): Check OPTION->new_flags beside
OPTION->new_value. Add new argument FLAGS.
(gc_component_change_options): Support default flag correctly.
(change_options_program): Likewise.
