The naming is inspired by Unbound's "outgoing-interface".

The format of TA store is compatible both ways with old kresd.
Note: it requires the parent commit to work, i.e. new libzscanner.

Comment parsing will only be supported in future libzscanner version.
Also move out of the module, as trust_anchors.lua requires it and isn't
in a module.

... and perform extra checks when converting from the floating-point
number.

It will be a useful idiom for IP address storage and correct conversion
of sockaddr* pointers.

engine_cmd() doesn't print the error() exceptions thrown from lua;
it only leaves the message on lua stack.

- 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.

- 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

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...

This might help if the lua command returns an unexpected number of
arguments.

That's to allow tunnelling the TTY to a different endian.

It was possible to write past the end of the buffer, if very unlucky.

The build system is prepared for libedit.

... 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.

Fixes #147.

I believe it was unused, so no risk was caused, but better remove it.
There's the complication that its signature has changed since libknot-2.4.0.
