It seems a bit cleaner, though impact on size and load speed should not
be noticeable.  We simply install most of the lua code, as before, and I
assume that we *do* want to keep that visibility, at least by default.

lib/root-hints.inc: improve regeneration safeguards

- Drop all make dependencies, so it's only generated when the file
  goes missing (i.e. was explicitly deleted).
- Add checks into the generator to avoid producing empty strings on
  failures.  It compiled correctly and wasn't easy to debug.

See merge request !79

lua ffi bindings: fix incorrect structs

Some structures have changed but lua was still using the old ABI.
I think no our lua code used the fields misplaced due to this,
except an example in documentation.

I didn't check much of the ABI in there.  I wish I knew some
(half-)automatic way how to do that.

Copy new query flags from lib/rplan.h to lua

Allow to override hostname() with a lua call hostname("example.com")

This changes lua hostname() call to accept optional parameter with new hostname. This is needed to override possibly wrong name used for ephemeral certs.

Fix osx sed

See merge request !70

That way we should notice breakages like this before merging.

\t escape is a non-standard escape sequence. Thanks Marek for reporting!

- The API and ABI for modules changes slightly (details below).
  KR_MODULE_API is bumped to avoid loading incompatible code.
  We have bumped libkres ABIVER since the last release 1.1.1,
  so leaving that one intact.

- Make KR_STATE_YIELD not reuse 0 value anymore.
  It's easy to e.g. return kr_ok() by mistake.
- struct kr_layer_t:
  * ::mm was unused, uninitialized, etc.
  * Make ::state an int, as it was everywhere else.
  * void *data was ugly and always containing struct kr_request *
- struct kr_layer_api:
  * Drop the void* parameter from ::begin, as it was only used
    for the request which is available as ctx->req anyway
    (formerly ctx->data).
  * Drop ::fail.  It wasn't even called.  Modules can watch for
    KR_STATE_FAIL in ::finish.
- Document the apparent meaning of the layer interface, deduced mainly
  from the way it's used in the code.  Caveats:
  * enum knot_layer_state handling seems to assume that it holds exactly
    one of the possibilities at a time.  The cookie module does NOT
    follow that (intentionally), apparently depending on the exact
    implementation of the handling at that moment.  It feels fragile.
  * I was unable to deduce a plausible description of when ::reset is
    called.  It's practically unused in modules, too.

It causes lots of line changes, but it would be confusing to keep the
current state over long term.

modules/daf: document restriction on order of loading

make: strip *.lua as intended since dcd89700

This saves a few kilobytes in the executable.

Also, the name XXD seemed no longer suitable, as it does lua-specific cleaning.

zonecut: add missing AAAA hints for E and G servers

The other records seem OK. Fixes #100.

Fixes #100.
The file with the addresses is in the repo, so people don't have to
regenerate it, but the build system is able to do it.

lru: new implementation and also interface

The implementation is now a hybrid, slightly described at top of `lib/generic/lru.h`.  Also the API is changed a bit, leading to slight simplification of our use patterns. (EDITED)

See merge request !44

... and that doesn't necessarily mean that malloc() failed.
We do *not* want to evict a heavy-hitter by an unfrequent element.

Note: even the implementation currently in master *did* return NULL,
so some parts of the code were just wrongly returning ENOMEM.

The implementation is now similar to set-associative caches
that x86 CPU use.  Also the API is changed a bit, leading to
slight simplification of our use patterns.

`make bench` now runs a predefined set of
microbenchmarks (right now LRU), it's a start
for comparative microbench of internal structures

The Makefile isn't perfect. I noted it doesn't clean the bench,
but we have the same problem for some other parts, e.g. in deckard.

add option to reorder cached RRs in answers

Fixes https://gitlab.labs.nic.cz/knot/resolver/issues/93.
API of a KR_EXPORT function is changed, so ABIVER is bumped.
