Verify and clean up client ID and global DUID config values before use, in order to prevent DHCP client malfunction and loss of IPv4 and/or IPv6 connectivity. - Accept common separators in the string (colon, dash, spaces/tabs, lf) - Ignore invalid values (non-hex or odd-numbered length) - Log a warning for invalid settings The fall back mechanism is as follows: If a (user-configured) network.<ifname>.clientid setting is found invalid, ignore and fall back to using network.globals.dhcp_default_duid. In case that's also invalid (e.g. has been tampered with), don't pass a client ID to updhc/odhcpc. In that case, udhcpc/odhcpc will use their defaults, which currently is the i/f MAC address resp. the i/f DUID-LL. Only error handling is introduced, no behavior change for valid settings.
