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

Resolve libknot and libzscanner SONAME at the build time and fixes to bootstrap-depends.sh script

The OS X build is still failing, but it's unrelated to these changes.

and set libknot_SONAME and libzscanner_SONAME as lua literals.

Remove now obsolete libpath lua function - use find_soname from
platform.mk to define <arg>_SONAME, add lua_pushliteral to
daemon/engine.c and add -D to daemon/daemon.mk for any new library
loaded from Lua.

Early awareness notification: a new lua module `version`
to periodically check for newer version on server and for CVE.

Also avoid that extremely long line.

worker: avoid uninitialized pointers

The cookie module could segfault due to the `opt` pointer not being initialized when no EDNS was sent in the incoming request.
