Thanks to Marek for noticing it.

It fired also when the name didn't contain the final dot.

We use it as relatively high-level function, often on user-input names,
so it seems suitable that it does convert the case.
This fixes cache.clear('Example.Org.'), and probably also negative trust
anchors and policy uses.

Problem was caused by our lookup format where only the root zone starts
with \0 and all other zones start differently. This caused
cache_match('.') to match only data from root zone.

This is handy mainly for tests but it costs nothing so why not to do it.

Error message is now contains apex name and advice how to clear negative
proofs.

Also make the CLI table-printer print a bit longer strings
than it used to.

WIP: needs at least review, perhaps some more modifications

... thanks to new API in libknot-2.7.
Apart from being simpler, it now rotates even uncached answers.

When at it, switch to generating the libzscanner bindings.

The _t isn't uint8_t* anymore but a structure with .len and .data.

To work on RRSIG TTLs, libknot >= 2.7.1 is needed.

Previously multiple kresd processes might use the same .lock file at
once and thus have a race between writing and renaming.  That could
happen relatively often if starting many instances *at once*.

The catch is that during configuration file processing,
no cache is open (yet), as kresd can't know if the config
does open it in some later part (with non-default path or size).
Now we just throw an error.  Exceptions:
 - cache.open() and cache.backends(), of course :-)
 - cache.ns_tout() - not required, it's not really inside cache
 - cache.close() - it sounds reasonable to allow "closing a closed cache"

This immediately caught a typo in cache metatable.

Previously the module was created on configuration time, so it wasn't
possible to inject custom endpoints to the default interface.

The handlers in Lua can now store per-request variables that are automatically
GC'd when the request is finished. This is useful for stateful modules,
such as DNS64 that uses internal option flags for state tracking.

The layers can now get a variable table like so:

```
local vars = kres.request_t(r):vars()
vars.hello = true
```

The variables are persisted between different layers for each request.
