19c51cfa49 Tidy and fix cache->uid handling. 
Some CNAMES left the value of ->uid undefined.

Since there are now special values if this, for CNAMES
to interface names, that could cause a crash
if the undefined value hit the special value.

Also ensure that the special value can't arise
when the uid is encoding the source of an F_CONFIG
record, in case there's a CNAME to it.

ee4158678a Use DS records as trust anchors, not DNSKEYs. 
This allows us to query for the root zone DNSKEY RRset and validate
it, thus automatically handling KSK rollover.
