trx_assign_rseg_low(): Skip dedicated undo tablespaces if
innodb_undo_tablespaces=0 has been set after the database was created.

When dropping a partially created table due to failure,
use SQLCOM_TRUNCATE instead of SQLCOM_DROP_DB, so that
no foreign key constraints will be touched. If any
constraints were added as part of the creation, they would
be reverted as part of the transaction rollback.

We need an explicit call to row_drop_table_for_mysql(),
because InnoDB does not do proper undo logging for CREATE TABLE,
but would only drop the table at the end of the rollback.
This would not work if the transaction combines both
RENAME and CREATE, like TRUNCATE now does.

If a table had a KEY_BLOCK_SIZE attribute, but no ROW_FORMAT,
it would be created as ROW_FORMAT=COMPRESSED in InnoDB.
However, TRUNCATE TABLE would lose the KEY_BLOCK_SIZE attribute
and create the table with the innodb_default_row_format (DYNAMIC).

This is a regression that was introduced by MDEV-13564.

update_create_info_from_table(): Copy also KEY_BLOCK_SIZE.

The error handling in the MDEV-13564 TRUNCATE TABLE was broken
when an error occurred during table creation.

row_create_index_for_mysql(): Do not drop the table on error.

fts_create_one_common_table(), fts_create_one_index_table():
Do drop the table on error.

create_index(), create_table_info_t::create_table():
Let the caller handle the index creation errors.

ha_innobase::create(): If create_table_info_t::create_table()
fails, drop the incomplete table, roll back the transaction,
and finally return an error to the caller.

lock_rec_queue_validate(): Assert page_rec_is_leaf(rec), except when
the record is a page infimum or supremum.

lock_rec_validate_page(): Relax the assertion that failed.
The assertion was reachable when the record lock bitmap was empty.

lock_rec_insert_check_and_lock(): Assert page_is_leaf().

MDEV-17804: Galera tests cause mysql_socket.h:738: inline_mysql_socket_send: Assertion `mysql_socket.fd != -1' failed.

Do not do end of statement logic if thd is already killed as
socket is already closed.

Problem was that controlling connection i.e. connection that
executed the query SET GLOBAL wsrep_reject_queries = ALL_KILL;
was also killed but server would try to send result from that
query to controlling connection resulting a assertion
mysqld: /home/jan/mysql/10.2-sst/include/mysql/psi/mysql_socket.h:738: inline_mysql_socket_send: Assertion `mysql_socket.fd != -1' failed.
as socket was closed when controlling connection was closed.

wsrep_close_client_connections()
	Do not close controlling connection and instead of
	wsrep_close_thread() we do now soft kill by THD::awake

wsrep_reject_queries_update()
	Call wsrep_close_client_connections using current thd.

Disable galera_3nodes tests using xtrabackup.

Disable galera tests using xtrabackup.

Record result files for 10.2.

Add test case for encrypted and page compressed tables.

recv_addr_trim(): Do not try to detach the hash bucket, because
the code for doing that does not always work.

recv_apply_hashed_log_recs(): Do not attempt to read pages for which
there exist no redo log records.

for debug build.

Skip tests which expectedly fail when Aria is not used for temporary tables

Remove unnecessary have_debug requirement, record results using
release build and create .rdiff file for debug builds where
needed.

Commit ff88e4bb broke the Windows build.
Clean up one more redundant #include to fix it.

lock_discard_page(): Traverse and discard the B-tree record locks
only if they exist. Else, discard the R-tree (spatial) index locks.

Compare against the correct constant 0. NOT_KILLED belongs to
enum killed_state, while THD_IS_NOT_KILLED is what we want.

Record .rdiff file for debug build and record .result file using
product build.

Add proper wait conditions to second node before continuing test.

THD::close_temporary_tables(): Revert the change.

ha_innobase::delete_table(): Move the work-around inside
a debug assertion, and check thd_kill_level() instead of thd_killed(),
because the latter would not hold for KILL_CONNECTION.

For prepare statemtent/stored procedures we rollback the items to original
ones after prepare execution in the function reinit_stmt_before_use.
This rollback is done for group by, order by clauses but is not done for
the window specification containing the order by and partition by clause of the
window function.

MDEV-17726 Assertion `sqlcom != SQLCOM_TRUNCATE' failed in ha_innobase::delete_table after truncating temporary table

THD::close_temporary_tables(): Assign lex->sql_command so that
the debug assertion will not fail in ha_innobase::delete_table().

Alternatively, we could ensure that thd_killed() holds inside
ha_innobase::delete_table().

There should be no impact for the non-debug build. The thd_sql_command()
inside ha_innobase::delete_table() only affects the treatment of
persistent FOREIGN KEY metadata. There is no persistent metadata
nor foreign key constraints for temporary tables.

No test case was added, because the failure is nondeterministic.

The fix for "MDEV-17698 MEMORY engine performance regression"
previously fixed this problem.

- Adding the test for MDEV-17724
- Re-recording wrong results for tests:
  * engines/iuds/r/insert_number
  * engines/iuds/r/update_delete_number
  which started to fail since MDEV-17698

Also, backporting a part of:
  MDEV-11485 Split Item_func_between::val_int() into virtual methods in Type_handler
for easier merge to 10.3.
