Subject: [PATCHv3 0/3] z3fold: background page compaction

The coming patchset is another take on z3fold page layout
optimization problem. The previous solution [1] used
shrinker to solve the issue of in-page space fragmentation
but after some discussions the decision was made to rewrite
background page layout optimization using good old work
queues.

The patchset thus implements in-page compaction worker for
z3fold, preceded by some code optimizations and preparations
which, again, deserved to be separate patches.

Changes compared to v2:
- more accurate accounting of unbuddied_nr, per Dan's
  comments
- various cleanups.
