Provided IBM System Z have outdated compiler version, which supports gcc sync
builtins but not gcc atomic builtins. It also has weak memory model.

InnoDB attempted to verify if __sync_lock_test_and_set() is available by
checking IB_STRONG_MEMORY_MODEL. This macro has nothing to do with availability
of __sync_lock_test_and_set(), the right one is HAVE_ATOMIC_BUILTINS.

MDEV-9249 MariaDB un-buildable on linux64: fails @ "error: ‘ERR_remove_state’ was not declared in this scope" when linking against OpenSSL 1.0.2e

ERR_remove_state is deprecated, use ERR_remove_thread_state
if possible

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.

A string definition is inconsistent and thus causes a compilation error.

Fixed compile warning related to if statement always being true. The if
statement can not be false, as the address of a member field is always
true.

Removed unused functions from tokudb_dump.cc.

This patch fixes another compilation error caused by specifying
attribute nonnull for all the parameters of the copyout function. This
is incorrect as the function actually gets called with null parameters
indirectly and thus only the output parameter should be nonnull.

This patch fixes one compilation error related to __db_lsn struct. The
struct can not be defined as empty according to the main C standard.
In C++, this is handled by forcing a size of 1. To eliminate the error
we add a dummy char field of size 1. This has no effect on the C++
compiled code, but also removes the compiler error.

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.
