Jon Shallow c0559e37b4 option checking: Do further option syntax checking for incoming PDUs ...

Extend coap_option_check_critical() for repeating options that are not
repeatable, so 4.02 error code can be returned.
https://www.rfc-editor.org/rfc/rfc7252#section-5.4.5

Check for option Proxy-Scheme and return 4.02 if option Uri-Host is
not present.

Clear M bit for option Block2 in a request as it must be ingnored on reception.
https://datatracker.ietf.org/doc/html/rfc7959#section-2.2

check_repeatable() now is coap_option_check_repeatable() (still internal).
