Split ER_NO_SUCH_TABLE into ER_NO_SUCH_TABLE and ER_NO_SUCH_TABLE_IN_ENGINE to be able to distingus if a .frm file is missing or if the table is missing in the engine.

MDEV-405: Server crashes in test_if_skip_sort_order on EXPLAIN with GROUP BY and HAVING in EXISTS subquery
- Testcase

- Don't do early cleanup of uncorrelated subqueries if we're running an EXPLAIN.

        the fill_help_table-5.5.sql file was copied into mariadb.

per-file comments:
  scripts/fill_help_tables.sql
        MDEV-471 update help tables.

force -fno-strict-aliasing for oqgraph

The problem was that was_null and null_value variables was reset in each reexecution of IN subquery, but engine rerun only for non-constant subqueries.

Fixed checking constant in Item_equal sort.
Fix constant reporting in Item_subselect.

Various places in the server replication code was incorrectly quoting
strings, which could lead to incorrect SQL on the slave/mysqlbinlog.

fix mysys/waiting_threads.c to compile w/o performance schema
include clients. scripts and manpages in -DWITHOUT_SERVER

only add cmake as a build dependency for distributions, where cmake is recent enough

Item::get_date() should return 1 unless the value is a valid date.

two tests still fail:
  main.innodb_icp and main.range_vs_index_merge_innodb
  call records_in_range() with both range ends being open
  (which triggers an assert)

increase xtradb verson from 13.0 to 13.01
