It's now a directory, one C file for each lua table of functions.
We get more total lines due to per-file copyright headers,
but the original file was just too long (nearing 2k lines).
The layout was inspired by the lib/cache/ split.

Disadvantage: git operations (e.g. blame) will stumble on this commit.

During the move, rename the "str" and "xstr" macros, too.
Otherwise there are no real changes, as they would be hard to spot.

Almost.  A trivial lib/layer/cache.c remains.
I put all lib/generic/*.h into libkres_HEADERS, to be sure.
They rarely change anyway.

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
