gpg,sm: Add STATUS_ERROR keydb_search and keydb_add-resource.

Browse source 
* g10/keydb.c (keydb_add_resource): Make ANY_REGISTERED
file-global.  Write a STATUS_ERROR.
(maybe_create_keyring_or_box): Check for non-accessible but existant
file.
(keydb_search): Write a STATUS_ERROR if no keyring has been registered
but continue to return NOT_FOUND.
* sm/keydb.c (keydb_add_resource): Rename ANY_PUBLIC to ANY_REGISTERED
and make file-global.  Write a STATUS_ERROR.
(keydb_search): Write a STATUS_ERROR if no keyring has been registered
but continue to return NOT_FOUND.  Also add new arg CTRL and change
all callers to pass it down.
