Add a trusted_proxies CIDR-list config key alongside blocked_networks.
Generalize the blocked_networks parser into parseCIDRList and
cidrListEntries, which take the key name as a parameter, so both keys
share one parser rather than a second copy. An invalid entry aborts
startup naming the key and value; an omitted or empty key leaves the
list empty.
