- Add discovery to JSON tables
  When columns are not defined, CONNECT analyses the json file to find column definitions.
  This wors only on table that are an array of objects. Pair keys are used to generate the
  column names and pair values are used for its definition. When the LEVEL option is defined
  as a not null integer, the eventual JPATH is scanned up to the LEVEL value.

From the current one:
- Fix MDEV-7521 when column names are utf8 encoded (not a general multi-charset fix)

- Adds more to JSON discovery processing and UDF's

- Use PlugDup everywhere it replaces PlugSubAlloc + strcpy.

- Making result files to be ended by LF to avoid test failures

When the server starts up, check if the master-bin.state file was lost.
If it was, recover its contents by scanning the last binlog file, thus
avoiding running with a corrupt binlog state.

Temporary table count fix. The number of temporary tables was increased
when the table is not actually created. (when do_not_open was passed
as TRUE to create_tmp_table).

Add a testcase. The bug itself was fixed by the fix for MDEV-7316.

    Bug #49931          Incorrect type in read_log_event error
    Bug #49932          mysqlbinlog max_allowed_packet hard coded to 1GB

If somehow the COMMIT or XID event in an event group was missing, the code in
parallel replication to handle this was not sufficient, leading to server
deadlock.

InnoDB transaction lock printout.

MDEV-7458: Deadlock in parallel replication can allow following transaction to start replicating too early

In parallel replication, don't rollback inside ha_commit_trans() in case of
error.

The rollback will be done later, but the parallel replication code needs to
run unmark_start_commit() before the rollback to properly control the
sequencing of transactions.

I did not manage to come up with a reliable automatic test case for this, but
I tested it manually.

(Without this, it happened for me that realpath() failed returning
undef for the default vardir. This in turn caused mysql-test-run.pl to
delete the source mysql-test/ directory.)

Backport from 10.1, it's not nice to get one's source directory nuked
by a rouge mysql-test-run.
