wsrep_gtid_domain_id was incorrectly being parsed and stored
as a signed long number on the joiner node.

/var/run/mysqld must be created before wsrep recovery.

Update ExecStartPre scripts to not fail if 'galera_recovery'
script is not available.

MDEV-10412 fix WITH_ASAN option for 10.1

Disabled NoNewPrivileges until SELinux policy is fixed.

In the AFTER_SYNC case, semi-sync was taking the binlog file name from
the wrong place, so around binlog rotation it could be using the new
name with a position belonging to the previous binlog file name.

Remove unnecessary semicolon

THD's statement transaction handle (st_transactions::stmt)
should also be looked for registered htons while serving a
request to abort a transaction.

- Update test result (checked)

- Fixed the test
- Improved comment for wsrep_drupal_282555_workaround

During wsrep position recovery, galera_recovery.sh script
redirected mysqld's error log to a temporary file in order
to find the start position. This, however, will not work
if --log-error is configured for the server.

Fixed by using --log-error in command line instead of
redirection.

[Patch contributed by Philippe MARASSE]

The problem was caused by a merged semi-join, which contained a non-merged
semi-join, which used references to the top-level query in the left_expr.

When moving non-merged semi-join from the subquery to its parent, do not
forget to call fix_after_pullout for its Item_subselect. We need to do
that specifically, because non-merged semi-joins do not have their
IN-equality in the WHERE clause at this stage.

Do not set 'optimized' flag until whole optimization procedure is finished.

* MDEV-10294: Put testname into environment as MTR_TEST_NAME during MTR

* MDEV-10294: restructure mtr to allow --valgrind-option=--tool=XXX

* MDEV-10294: mtr valgrind - supressions all tools + feedback

Fixed threadpool_add_connection to use thd_prepare_connection()
to match thread-per-conection flow.

set the 'typelib' member for plugin boolean sysvars

don't call strlen() in the loop

a test case for a broken vcols behavior with different
charsets. this is fixed in 10.2

TABLE_SHARE::init_from_binary_frm_image has a rule: if an index
has a partially-covered column (like in "KEY(col(N))" ), then dont
provide "Extended Keys" feature for this index.

The problem was that due to coding error Extended Keys feature was
disabled for *ALL* subsequent indexes. Fixed the error.

The problem was introduced by 1859caf6:
  MDEV-10175: range optimizer calls records_in_range() for full extended keys

  Make the range optimizer not call records_in_range() when it would
  not give any benefit.

that patch used an incorrect way to check for full extended key. Now fixing
the check.

Add ProtectSystem=full, NoNewPrivileges=true, PrivateDevices=true, and ProtectHome=true to the systemd units.

MDEV-10211 : fix ssl test not to use specific value of ssl_cipher, as it can change between different openssl/yassl version

add a test case

Addreses are not necessarily between heap_start && heap_end. Malloc
calls using mmap can place pointers outside these bounds. In this case,
we'll warn the user that the query pointer is potentially invalid.
However, we'll attempt to print the data anyway after we're done
printing everything else.
