Problem was the use of SHOW PROCESSLIST. This is not fully functional in
embedded server, STATE is hardcoded to "Writing to net".

Fixed using --replace_result for STATE.

The test is supposed to provoke a deadlock, to test a crash of the server in
some deadlock scenarios.

The problem is that in recent version of MySQL, no deadlock occurs. It is not
clear why a deadlock should be expected. One transaction does an insert+delete
on primary key value 1 in table t2. The other transaction does an insert on
primary key value 123. There seems no reason that these should conflict, so
there is no deadlock.

(Presumably an earlier version did get a deadlock due to maybe taking excessive
locks on the insert+delete of primary key value 1. The table has only one row,
so maybe a different locking was used ("Impossible WHERE noticed after reading
const tables"))

Fix is to have transaction 1 lock PK 1 and transaction 2 lock PK 123. Then have
transaction 2 access PK 1 (wait) and transaction 1 access PK 123 (deadlock).

It has been checked that this modified test case still crashes the server in
the same way prior to fix of the original bug (Bug#24989).


mysql-test/include/read_many_rows.inc:
  Provoke deadlock on same PK value in the two transactions to ensure that the
  deadlock does occur independently on whatever execution plan is chosen.
mysql-test/r/read_many_rows_innodb.result:
  Result file update.

Some result updates necessary due to extra tables and columns added in
information_schema in MariaDB (XtraDB, PBXT, microsec_process).

Also fix bad merge of two result files; apparently the test case was merged,
but the result file was not.

  Since result file includes PBXT information_schema tables, we need PBXT to run this test.

The --enable_prepare_warnings allows to not discard warnings from autorepair
of crashed table in --ps-protocol mode.

Use this to properly fix the parts.partition_recover_myisam and
maria.maria-recover tests.

Add a test case for the new feature. This also adds missing test coverage
for the case where the same warning is thrown in both prepare and execute
phase.

- Include maria_chk and other maria binaries
- Include sql/$TARGET/mysqld.lib, like mainline does (but what is that useful for?)
- Don't include my_safe_{process,kill} garbage.
- call '/bin/find', not just 'find' is that is some incompatible windows command.

 - Don't need any m1 prefix for the first release based on given MySQL
   version number.

 - Fix mysql-test-run to understand that some stuff is installed under
   share/mariadb rather than share/mysql.

- Update EXPLAIN results after table elimination
- mysqlslap now specifies 'Engine=' in CREATE TABLE instead of using

  we can't be bothered to investigate at the moment, so add --replace

- Adjust CMakeLists.txt to follow latest mysql's expectations about plugins
- Add typecasts
- wrap pbms_enabled.cc in #ifdef

 - innodb-index needs regexp replace for embedded like other similar tests.

 - partitions_special_* need to be modified for the extension from 16 to 32
   max key parts allowed that was made in MariaDB.
