This is a 10.3 specific part of MDEV-13049.
It disables automatic sorting for
"SELECT .. FROM INFORMATION_SCHEMA.{SCHEMATA|TABLES}"
and adjusts the affected tests accordingly.

MDEV-13997 Change Item_bool_rowready_func2 to cache const items at fix time rather than evaluation time

Side effect: the second debug Note in cache_temporal_4265.result disappeared.

Before this change:
- During JOIN::cache_const_exprs(),
  Item::get_cache() for Item_date_add_interval() was called.
  The data type for date_add('2001-01-01',interval 5 day) is VARCHAR,
  because the first argument is VARCHAR (not temporal).
  Item_get_cache() created Item_cache_str('2001-01-06').
- During evaluate_join_record(), get_datetime_value() was called,
  which called Item::get_date() for Item_cache_str('2001-01-06').
  This gave the second Note. Then, get_datetime_value() created
  a new cache, now Item_cache_temporal for '2001-01-06', so not
  further str_to_datetime() happened.

After this change:
- During tem_bool_rowready_func2::fix_length_and_dec(),
  Arg_comparator::set_cmp_func_datetime() is called,
  which immediately creates an instance of Item_cache_date for
  the result of date_add('2001-01-01',interval 5 day).
  So later no str_to_datetime happens any more,
  neither during JOIN::cache_const_exprs(),
  nor during evaluate_join_record().

        bind_address variable added.

Forgot to put the updated rocksdb.result in

Downscale rocksdb.add_index_inplace_sstfilewriter to be 10x smaller

Fix a race condition in the testcase.

ReadFile/WriteFile operations.

Innodb opens files with FILE_FLAG_OVERLAPPED. lpNumberOfBytesRead/Written
are documented to be potentially inaccurate in this case,
(possibly even if async operations complete synchronously?)

The fix is to always pass NULL for the correspondng parameters,
as recommended by  MSDN. Read the actual counts with
GetQueuedCompletionStatus() or GetOverlappedResult().

os_file_get_size(): Use fstat() instead of calling lseek() 3 times.
In this way, concurrent calls to this function should not interfere
with each other.

Suggested by Vladislav Vaintroub.

The predicate page_is_root() would not hold if btr_create() fails
before the root page is fully initialized. Move the debug assertion
from btr_free_root_invalidate() to its other caller,
btr_free_if_exists(). In that caller, we actually already checked
for page_is_root().

os_file_set_size(): Sometimes the file already is large enough.
Avoid calling posix_fallocate() with a non-positive argument.
Also, add a missing space to an error message.

Adjust and enable rocksdb.2pc_group_commit test

With this patch, parameters passed to posix_fallocate() will be
the same as they were prior to refactoring in  commit b731a5bc

In particular, 'offset' parameter for posix_fallocate is again current_file_size
and 'length' is new_file_size - current_file_size.

This seems to fix crashes on ancient Linux (kernel 2.6).

The assertion failure was relaxed in
commit 02ba15a9
but it was not enough, because another assertion would fail.

trx_undo_free_prepared(): Allow any undo log state. For transactions
that were resurrected in TRX_STATE_COMMITTED_IN_MEMORY
the undo log state would have been reset by trx_undo_set_state_at_finish().

The redo log record MLOG_UNDO_HDR_DISCARD is never written, and
the function trx_undo_discard_latest_update_undo() is never called
outside crash recovery.

Starting with MariaDB 10.2.2, crash recovery from an older InnoDB
version is refused. Therefore, we can safely remove the code for
parsing this long-unused redo log record type.

The use of MLOG_UNDO_HDR_DISCARD was removed by Heikki Tuuri,
the original designer and author of InnoDB, more than 13 years ago:

  commit 3caab0f3
  Author: unknown <heikki@hundin.mysql.fi>
  Date:   Thu Mar 18 14:57:22 2004 +0200

    trx0undo.h, trx0undo.c, trx0trx.c:
      Update an obsolete comment about trx commit: we can no longer call
      trx_undo_update_cleanup_by_discard(), and actually, the idea to
      call it was erroneous, it cannot work

trx_free_prepared(): The function trx_resurrect_insert()
can resurrect a committed transaction when the TRX_UNDO_STATE
field is not TRX_UNDO_ACTIVE or TRX_UNDO_PREPARED.
(In the examined failure of mariabackup.xb_compressed_encrypted,
assertion failure in --apply-log shutdown at line 25,
the TRX_UNDO_STATE strangely contained the value 0xffff.)

In any case, the assertion must allow the state
TRX_STATE_COMMITTED_IN_MEMORY for resurrected transactions.

Apply fix for https://github.com/facebook/mysql-5.6/issues/748
A few tests in rocksdb suite fail with --ps-protocol

They fail because --ps-protocol uses different data format on the
wire. Work around that by doing a dummy CONCAT operation which forces
the data to be transfered in text form (like it is done without
--ps-protocol)
