We no longer need it and it's just confusing,
e.g. the bit assignments were ignored now.

sed -e 's/flags |= QUERY_\([A-Z0-9_]*\);/flags.\1 = true;/g' \
        -e 's/flags &= ~QUERY_\([A-Z0-9_]*\);/flags.\1 = false;/g' \
        -e 's/\(flags\|options\|opts\) & QUERY_\([A-Z0-9_]*\)\()\| ||\)/\1.\2\3/g' \
        -i $(git grep -l QUERY_)

I didn't recall this doesn't work on Darwin.

... even if LIBDIR isn't on a standard place.

The description didn't match the reality.  Change docs for now,
even though 1% seems a bit too little to me personally.

It seemed a bit strange to have 'stats' module collect expiring records
in an LRU, then once a few minutes convert that via JSON to a lua table,
and put those records into prefetching queue.  Apart from complexity,
it wouldn't work well with short TTLs typical for today's CDNs, e.g. 30
or 60 seconds.

Our security policy prevented those from reaching cache,
crippling the feature.

Closes #154.

I'm sorry I broke the module in 06b0d3d4.  Thaks Vita!

... to allow NEWS update

The epoch indices are from [1..period].

i.e. downgrade a zone to insecure when *all* DNSKEYs of the apex are
unverifiable due to unimplemented DNSKEY or DS algorithms.

Closes #204.

... to fix conflict in NEWS.

Which semantically reverses part of fbe88ccd.
I would personally prefer not to, but I guess it would be less consistent.
Also make the error messages a little better.

Almost all of them were getting redirected correctly, but why keep the
old ones.  Also update a couple nitpicks directly around.

I broke this in 3da1535e when changing stuff around addr2reverse;
now it should be OK, after partially reversing that commit.
I'm sorry.  Thanks to Vita for noticing the breakage.

At least it seems so...
