stty: ensure no side effects from invalid options
* src/stty.c (apply_settings): A new function refactored
from main() that is used to both check and apply options.
(main): Call apply_settings before we open the device,
so all validation is done before interacting with a device.
* NEWS: Mention the improvement.
* tests/misc/stty.sh: Add a test case.
