On shutdown feedback was sending a short report without creating
a THD. At that point current_thd was pointing to the already
destroyed THD from the previous full report.

backport from 10.1:

      don't let current_thd to point to a destroyed THD

10.0 has an "analyze table .. persistent for all" syntax. This adds
--persistent to mysqlcheck(mysqlanalyize) to perform this extended
analyze table option.

Removed exit() from daemon_example, pass error to caller instead.
Also removed unused my_abort_hook.

Check now allows zero length decimals too.

(backporting Adam Chainz patch to 10.0)

they used to be unstable, fixed in 7.1.8
and apparently broken again now

* mostly update result files
* also updating test/include files to match 5.6

* use --sort_result in test files as needed
* remove old and wrong mariadb-5.3 related partitioning hack
   from ha_tokudb.cc

Fixed moving charset from definition to the value.

Update modified-counter also if update effects non-indexed columns.

MDEV-9276: MySQL Bug #78754: FK definitions missing from SHOW CREATE TABLE in "innodb_read_only" mode

Fix logic around retrying failed Windows async IO as synchronous IO . os_file_write/read macros were wrong (had wrong number of args), among other things

  modified:   storage/connect/tabjson.cpp

MDEV-7655 SHOW CREATE TABLE returns invalid DDL when using virtual columns along with a table collation

that was mistakenly merged from mysql-5.5.47

(introduces valgrind failures in main.sp, because Field_varstring
columns are created as FIELD_NORMAL and that causes aria to
read bytes between the actual value length and field max length)

that was mistakenly merged from mysql-5.5.47

Make dependency on mysql-common package in debian/control
versioned to force that it is installed together with the other
mariadb-* packages. This ensures that the init.d and systemd
files for MariaDB mysqld are the ones from MariaDB.org repos.

This is useful for developers who run autobake-deb.sh directly
from the source tree as the resulting source tar package will be
90% smaller and all operations regarding it consequently 10x faster.
