Use ENABLE_cookies=yes variable to compile functionality.

this module is superseded by http module, removing

this change introduces new API for cache backends,
that is a subset of knot_db_api_t from libknot
with several cache-specific operations

major changes are:
* merged 'cachectl' module into 'cache' as it is
  99% default-on and it simplifies things
* not transaction oriented, transactions may be
  reused and cached for higher performance
* scatter/gather API, this is important for
  latency and performance of non-local backends
  like Redis
* faster and reliable cache clearing
* cache-specific operations (prefix scan, ...) in
  the API not hacked in
* simpler code for both backends and caller

this allows to override any dstdir variable without
patching config.mk

this module allows to rewrite address ranges in answers to different address ranges specified in configuration

same for LDFLAGS. this fixes common problem where CFLAGS after make
was evaluated as a make variable and replaced the default, while
before as env variable and was prepended to the default string.
now they both behave as an env. variable

module can identify clients based on their source address or used TSIG
key

by default it blocks queries to private zones, can be extended to match anything in the query content (i.e. water torture style attacks)

the Redis backend supports UNIX, TCP and custom ports
no real transactions nor iteration, but it’s not needed at the moment
transactions keep replies in a freelist, which is purged on transaction
commit / abort

memcached is a distributed caching system, it is a good fit
for building resolvers with shared and replicated cache

this hooks into query resolution and collects counters on answers, queries and iterator

the build system now doesn't always relink targets
