shared/ip-procotol-list: generalize and rework parse_ip_protocol()
Optionally, accept protocols that don't have a known name. Avoid any allocations in the common case. Return more granular error codes: -ERANGE for negative values, -EOPNOTSUPP if the protocol is a valid number, but we don't know the protocol, and -EINVAL only if it's not a numerical string.
