* priv.h (nosuid, noexec): New variables.
* init-init.c (nosuid, noexec): New variables, initialized to zero.
* file-exec.c (diskfs_S_file_exec): If noexec is on, then prohibit
all execution with EACCES. If nosuid is on, then prohibit setuid
or setgid execution by silently omitting the uid substitution.
* opts-std-startup.c (parse_startup_opt): Implement --no-suid and
--no-exec.
* opts-common.c (diskfs_common_options): Add --no-suid and
--no-exec.
* opts-std-runtime.c (struct parse_hook): Add nosuid and noexec.
(parse_opt) [cases 'S', 'E', OPT_SUID_OK, OPT_EXEC_OK] Understand
--no-suid, --no-exec, --suid-ok, and --exec-ok.
(parse_opt) [case ARGP_KEY_INIT]: Initialize H->nosuid and
H->noexec.
(OPT_SUID_OK, OPT_EXEC_OK): New macros.
(std_runtime_options): Add --suid-ok and --exec-ok.
(set_opts): Set nosuid and noexec from H->nosuid and H->noexec.
* opts-common.c (diskfs_common_options): Rename --nosync to
--no-sync; leave --nosync as an alias.
