The ALTER TABLE…IMPORT TABLESPACE adjustment code that was introduced by
WL#5522 in MySQL 5.6 is incorrectly invoking rec_get_status() on a
ROW_FORMAT=REDUNDANT record to determine if a record is a leaf page record.
The function rec_get_status(rec) is only to be called on
ROW_FORMAT=COMPACT, DYNAMIC or COMPRESSED records.

log_group_read_log_seg(): Only display the message during recovery,
not during normal operation. When the XtraDB configuration parameter
innodb_log_archive is set, this function will be called during
normal operation.

followup for 378beed0 - only count WARN_LEVEL_ERROR,
not warnings or notes.

tabtyp was defined under ODBC_SUPPORT, but used
outside of it too (under JDBC_SUPPORT).

don't prepare for checking view's CHECK OPTION, if
there is no CHECK OPTION in the first place.

Binlog_background_thread does not make a call to set_time(), And when
we call binlog_checkpoint_log_event->write() , we write the wrong timestamp.
In this patch we correct this by calling thd->set_time().

MDEV-13290: Assertion Assertion `!is_set() || (m_status == DA_OK_BULK && is_bulk_op())' or `! is_set()' failed

followup for 97c2a735 - don't use thd->is_error(),
the error could've been set before TABLE_LIST::cleanup_items.
Use the error handler to count errors.

This fixes rpl.rpl_row_binlog_max_cache_size - it was failing when
ER_STMT_CACHE_FULL happened duing multi-table update. Because
multi_update::abort_result_set() calls do_updates() to update
as much as possible, so one cannot rely on thd->is_error() after that.

disable Mongo in 10.0, compiler warnings.

MDEV-13290: Assertion Assertion `!is_set() || (m_status == DA_OK_BULK && is_bulk_op())' or `! is_set()' failed

Check error status which can be set by conversion procedures.

        The MySQL 5.6 doesn't always send the MYSQL_AUDIT_GENERAL_LOG
        notification. So we have to suppress the log_current_query()
        in this case.

Revert Bug #25175249  ASSERTION: (TEMPL->IS_VIRTUAL && !FIELD) || (FIELD && FIELD->PREFIX_LEN ? FIELD

We don't want this in innodb/xtradb

* CMakeLists.txt erroneous duplicated lines.
* Unneded differences in tabjson.cpp
* Unneded space differences in jdbconn.{cpp|h}

This is a squashed merge.

MDEV-13685 Can not replay binary log due to Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8mb4_general_ci,COERCIBLE) for operation 'concat'

- the probably ultimate fix for dependencies on VS
- remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in
cmake 3.9
- simplify signing targets on Windows.
- remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds
in the same package

recv_reset_logs(): Initialize the redo log buffer, so that no data
from the old redo log can be written to the new redo log.

This bug has very little impact before MariaDB 10.2. The
innodb_log_encrypt option that was introduced in MariaDB 10.1
increases the impact. If the redo log used to be encrypted, and
it is being resized and encryption disabled, then previously
encrypted data could end up being written to the new redo log
in clear text. This resulted in encryption.innodb_encrypt_log
test failures in MariaDB 10.2.

The SEARCH_ABORT logic was not working as intended
(tests were not being aborted).

In XtraDB, buf_block_get_frame() can return NULL, and this value
can be passed to buf_page_print(). Do not declare the parameter
as nonnull.

buf_page_print(): Remove the parameter 'flags',
and when a server abort is intended, perform that in the caller.

In this way, page corruption reports due to different reasons
can be distinguished better.

This is non-functional code refactoring that does not fix any
page corruption issues. The change is only made to avoid falsely
grouping together unrelated causes of page corruption.
