Details:

Most systems allow a hosts file so that a few static IP addresses can be
defined, say for things on a local subnet which can't be resolved.

This patch adds a callout to 'dns.c', provisionally called
sys_hosts_file_dns_lookup() for want of a better name. This allows (under the
control of define DNS_HAS_HOSTS_FILE) a system specific hosts file to
optionally return a result.

Some systems may opt to cache the hosts file in RAM, others may parse its
contents and store in a compact form, other mays need to scan a disc drive
(hence sys_ territory).
