Provided IBM System Z have outdated compiler version, which supports gcc sync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.

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.

don't let current_thd to point to a destroyed THD
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.

Backport pull request #125 from grooverdan/MDEV-8923_innodb_buffer_pool_dump_pct to 10.0
WL#6504 InnoDB buffer pool dump/load enchantments
This patch consists of two parts:
1. Dump only the hottest N% of the buffer pool(s)
2. Prevent hogging the server duing BP load
From MySQL - commit b409342c43ce2edb68807100a77001367c7e6b8e
Add testcases for innodb_buffer_pool_dump_pct_basic.
Part of the code authored by Daniel Black
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)
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.
