Do not require uploaders to be present in the system passwd database.
* src/wydawca.h (access_method_id): Remove verify_method, gpg_key_method and user_data_method. Add project_uploader_method. (uploader_info): New structure. (struct file_triplet): Remove gid and user data fields. Add uploader_count, uploader_list and uploader. (TRIPLET_GID): Change definition. (verify_directive_signature): Change signature. (uploader_find_frp): New proto. * src/verify.c (extract_plaintext): New function. (fill_project_name): Rewrite. Parse directive file. (uploader_find_frp): New function. (check_access_rights): Remove. (verify_directive_file): Rewrite. * src/config.c (string_to_access_method_id): Reflect changes to the access method system. * src/builtin.c (default_ncol): Reflect changes to the access method system. * src/gpg.c (gpg_sig_ok_p): Remove. (gpg_verify_signature): New function, based on gpg_sig_ok_p. (verify_directive_signature): Remove `pubkey' argument. Register all public keys from the uploader list. Do not call directive_parse, as the directive file must already be parsed by the time the function is called. * src/mail.c (get_uploader_email): New function. (do_notify): Use get_uploader_email for notifying users. * src/triplet.c (hash_triplet_free): Reflect changes to the triplet structure. (format_file_data): Get user name from the system passwd database. (fill_user_data): Remove. (expand_user_real_name, expand_user_email): Reflect changes to struct file_triplet. * tests/etc/wydawca.rcin: Rewrite to reflect new access method system. * tests/mailstats.at, tests/notify-upl.at, tests/upload-dry.at, tests/upload.at: Update.
