MDEV-83 Cost-based choice for the pushdown of expensive predicates to joined tables

Commit of current work state. The commit implements a prototype of the task, where
the main things missing are:
- handling of semi-join nests (predicates cannot be moved outside of semi-join nests), and
- outer join restrictions on predicate moves

MDEV-342: Do not mark old binlog file as cleanly closed during rotate until
the new file is fully synced to disk and binlog index. This fixes a window
where a crash would leave next server restart unable to detect that a crash
occured, causing recovery to fail.
