trust anchor fixes

Closes #151

See merge request !193

- Remove abstraction of the refresh callback, as we always use the same
  function.  This way the code is significantly easier to understand.
- Add a couple more comments.

It was strange to keep it indefinitely, and the code was already
half-prepared for this change.  Theoretically, if a resolver has been
stopped for too long to miss a key's period of Revoked status, it would
continue to trust the key forever.

- The description was very misleading (far from reality).
- The removed condition in rrcache was bogus.

- printing refresh time in milliseconds could've been confusing;
- move syntactic sugar definitions close to the rest of the table;

... via trust_anchors.{bootstrap_url,bootstrap_ca}

- docs: fix cache.current_* since long ago d5272b4b
- don't allow "cache.foo = 'bar'" for abitrary foo
- restore cache['nic.cz'] after b31bad2ccf while not breaking completion
- #cache won't work on lua 5.1, so remove it

Fix -k argument processing to avoid out-of-bounds memory accesses

Mangling of keyfile_dir and allocation of keyfile_path led to rare
crashes (and Valgrind complaints).

The error was introduced in 21f3a6b9.

The FD leak happened only when we exit the process, but still...

... via "__binary" pseudocommand

That will allow us to discover the top-level symbols for completion.
For others we can e.g.: for n in pairs(net) do print(n); end
I must admit I fail to understand some of the related lua magic.

The theme is no longer included in newer Sphinx versions,
so some systems (at least) will require specifying it explicitly.
(The docs refuse to build without it.)

Closes #101.
