TODO items.
o #define BIT_... different on bigendian and smallendian systems so that
the htons on flags is not needed to send a message from the cache.
o speed up pkt domain name decompression loop detection using counter perhaps.
o detect OS/400 pthreads implementation that allows upgrading to writelock
on pthreads rwlocks and use it to examine-rd before storing-wr rrset cache.
o understand synthesized DNAMEs, so those TTL=0 packets are cached properly.
o understand NSEC/NSEC3, aggressive negative caching, so that updates to
NSEC/NSEC3 will result in proper negative responses.
o scrubber has slow pkt_subdomain and pkt_strict_subdomain functions.
o get serverselection algorithm out of local optimum.
make subtargets to get rtt info for a couple of targets, like fetch-policy.
or send out multiple queries to multiple servers.

get stats, get memstats, get ..., reload, clear one zone from cache
o watch for spoof nearmisses. Keep counter of nearmisses and print that
in the stats lines, operator can determine what level is a redalert.
o improve compression of DNS packets by first puttig uncompressible rrs, then
compress to their rdata.
o improve compression of DNS packets by first putting uncompressible rrs, then
compress to their rdata. Messes up the ordering of RRs, so bad for interop.
o NSID rfc 5001 support.
o timers rfc 5011 support.
o Treat YXDOMAIN from a DNAME properly, in iterator (not throwaway), validator.
