IT IS DONE IN-PLACE
With change buffer enabled, InnoDB doesn't write a transaction log
record when it merges a record from the insert buffer to an secondary
index page if the insertion is performed as an update-in-place.
Fixed by logging the 'update-in-place' operation on secondary index
pages.

* add TokuDB, together with the ft-index library
* cmake support, auto-detecting whether tokudb can be built
* fix packaging - tokudb-engine.rpm, deb
* remove PBXT
* add jemalloc
* the server is built with jemalloc by default even if TokuDB is not built
* documentation files in RPM are installed in the correct location
* support for optional deb packages (tokudb has specific build requirements)
* move plugins from mariadb-server deb to appropriate debs (server/test/libmariadbclient)
* correct mariadb-test.deb to be not architecture-independent
* fix out-of-tree builds to never modify in-tree files
* new handler::prepare_index_scan() method
After MDEV-4817, WHERE clause may be evaluated early, in fix_fields.
In ps-protocol fix_fields happens both for prepare and execute phase,
generating double the number of warnings from the early WHERE clause
executions.
ORDER BY does not work
Use "dynamic" row format (instead of "block") for MARIA internal
temporary tables created for cursors.
With "block" row format MARIA may shuffle rows, with "dynamic" row
format records are inserted sequentially (there are no gaps in data
file while we fill temporary tables).
This is needed to preserve row order when scanning materialized cursors.
When a non-nullable datetime field is used under an IS NULL predicate
of the WHERE condition in a query with outer joins the remove_eq_conds
function should check whether this field belongs to an inner table
of any outer join that can be, in a general case, a nested outer join.

sql/log_event.cc:
Added DBUG_PRINT
Set thd->first_successful_insert_id_in_prev_stmt_for_binlog when setting thd->first_successful_insert_id_in_prev_stmt.
This is required to get last_insert_id() replicated.
This is analog to how read_first_successful_insert_id_in_prev_stmt() works.
sql/rpl_utility.cc:
Added DBUG_PRINT
When in function remove_eq_conds() a sub-formula of the processed condition
is replaced for another formula we should ensure that in the resulting
formula AND/OR levels must alternate.
The patch to fix mdev-4418 turned out to be incorrect.
At the substitution of single row tables in make_join_statistics()
the used multiple equalities may change and references to the new multiple
equalities must be updated. The function remove_eq_conds() takes care of it and
it should be called right after the substitution of single row tables.
Calling it after the call of make_join_statistics was a mistake.
The bug was that if mysql.slave_gtid_pos was missing, operations on variables
gtid_slave_pos, gtid_binlog_pos, and gtid_current_pos would fail, and continue
to fail even after the table was fixed, until server restart.
Now setting the variables retry loading the table, succeeding if it has been
restored. And querying the variables when the table is not there acts as if
the table was there and was empty.
Also, attempt to fix a race in the rpl.rpl_gtid_basic test case.
The code of JOIN::optimize that performed substitutions for the best equal
field in all ref items did not take into account that a multiple equality
could contain the result of the single-value subquery if the subquery is
inexpensive. This code was corrected.
Also made necessary corresponding corrections in the code of make_join_select().
