Some global function definitions were orphaned by a bug fix in
MySQL 5.7.14 more than 2 years ago.
Remove them.

Implement undo tablespace truncation via normal redo logging.

Implement TRUNCATE TABLE as a combination of RENAME to #sql-ib name,
CREATE, and DROP.

storage/rocksdb/rdb_datadic.cc: In member function 'int myrocks::Rdb_key_def::unpack_integer(myrocks::Rdb_field_packing*, Field*, uchar*, myrocks::Rdb_string_reader*, myrocks::Rdb_string_reader*) const'

on ppc64le, ubuntu bionic gcc 7.3.0 and debian stretch gcc 6.3.0

The error happens with -ftree-loop-vectorize when trying to vectorize
a particular loop (see Rdb_key_def::unpack_integer())

Compiler gets confused by __attribute__((optimize("O0")) that comes from
ha_rocksdb_proto.h. The intention of this __attribute__ was to prevent
function from being inlined (see ha_rocksdb.cc). Let's use a more
specific attribute that prevents inlining but does not confuse
loop vectorizer.

An error in "group commit with MariaDB's binlog" code: we would flush
the WAL even when the transaction did not do any writes (and so the logic
in myrocks::Rdb_transaction::commit caused it to rollback).

Reset query cache after every test case and add wait after
load infile.

to guarantee that it's destroyed when plugin deinit is called, not after

Use RedHat-recommended /var/lib/rpm-state/mariadb/ for restart flag.
This also fixes SUSE where /var/lib/rpm-state doesn't necessarily exist.

cover ALTER TABLE

MDEV-16792 Assertion `m_status == DA_ERROR' failed in Diagnostics_area::sql_errno or wrong result upon SHOW TABLE STATUS after adding partition under ANSI_QUOTES

if opening a table fails with a syntax error, the error shouldn't
be suppressed completely as if it didn't happen at all.

Unary minus operation for the smallest possible signed long long value
(LONLONG_MIN) is undefined in C++. Because of this, func_time.test
failed on ppc64 buildbot machines.

Fixing the code to avod using undefined operations.

This is fix is similar to "MDEV-7973 bigint fail with gcc 5.0"

RPM solution:

Make all server plugins to restart the server when installed.
To avoid multiple server restarts, do it only once in posttrans scriptlet.
Add support for CPACK_RPM_<component>_POST_TRANS_SCRIPT_FILE

alloc_root(): unpoison only requested amount of bytes instead of a
possible bigger aligned-sized buffer.

For the original test in 10.0 it was not really important if
find_user_wild() or find_user_exact() is used in sp_grant_privileges().
sp-security.test passed with either of them.

Fixing the test so it reliably fails with find_user_wild()
and pass with find_user_exact().

Make different threads that are running data_copy_thread_func()
use the same pthread_mutex for locking (not the copies of the same
pthread_mutex_t).

Simplify, and make it work with system tablespace outside of
innodb data home.

Also, do not reread TRX_SYS page  in endless loop,
if it appears to be corrupted.

Use finite number of attempts.

		if custom undo tablespace is defined

- In case of multiple undo tablespace, mariabackup have to open system
tablespace to find the list of undo tablespace present in TRX_SYS page.
For opening system tablespace, mariabackup should fetch the file name
from already initialized system tablespace object.

Add wsrep_sync_wait as we want INSERT to fail.

Wait in second node until tables with databases are created.

Test changes only.
