Postfix: The pre-initialization of wsrep threads is not needed
for mysqldump sst method.

When a BF thread attempts to abort a victim thread's transaction,
the victim thread is not locked and thus its not safe to rely on
its data structures like htons registered for the trx.

So, instead of getting the registered htons from victim, innodb's
hton can be looked up directly from installed_htons[] and used to
abort the transaction. (Same technique is used in older versions)

Perform a post initialization of plugin-related variables
of wsrep threads after their global counterparts have been
initialized.

The crash is caused due to a race condition where wsrep
startup threads invoke ha_maria::implicit_commit() method
while maria_hton is partially initialized. The fix is to
skip this method if plugins are uninitialized.

MDEV-11195: Correct enablement of NUMA in innodb/xtradb

Added server variable compression_default, which if 1/ON sets compression on for all new InnoDB/XtraDB tables by default by setting PAGE_COMPRESSED=1

The .rdiff applied ok locally with my copy of patch, but failed with
"misordered hunks" on a test host. Maybe that host has a more strict
version of `patch`.

With "WL#6047 - Do not allocate trx id for read-only transactions"
m_prebuilt->trx->id is always 0 for read-only transactions. This makes
it useless as an index for fuzzy counters.

Use server thread id instead similarly to MySQL.

Conflicts:

BINLOG statement output by mysqlbinlog actually has the base64 of the
non-compressed event. So remove my previous incorrect review change,
which allowed compressed event types for BINLOG statement.

Also add a couple test cases for this, running mysqlbinlog | mysql.

            for InnoDB tables"

Don't use thr_lock.c locks for InnoDB tables. Below is list of changes that
were needed to implement this:
- HANDLER OPEN acquireis MDL_SHARED_READ instead of MDL_SHARED
- HANDLER READ calls external_lock() even if SE is not going to be locked by
  THR_LOCK
- InnoDB lock wait timeouts are now honored which are much shorter by default
  than server lock wait timeouts (1 year vs 50 seconds)
- with @@autocommit= 1 LOCK TABLES disables autocommit implicitely, though
  user still sees @@autocommt= 1
- the above starts implicit transaction
- transactions started by LOCK TABLES are now rolled back on disconnect
  (previously everything was committed due to autocommit)
- transactions started by LOCK TABLES are now rolled back by ROLLBACK
  (previously everything was committed due to autocommit)
- it is now impossible to change BINLOG_FORMAT under LOCK TABLES (at least
  to statement) due to running transaction
- LOCK TABLES WRITE is additionally handled by MDL
- ...in contrast LOCK TABLES READ protection against DML is pure InnoDB
- combining transactional and non-transactional tables under LOCK TABLES
  may cause rolled back changes in transactional table and "committed"
  changes in non-transactional table
- user may disable innodb_table_locks, which will cause LOCK TABLES to be
  noop basically

Removed tests for BUG#45143 and BUG#55930 which cover InnoDB + THR_LOCK. To
operate properly these tests require code flow to go through THR_LOCK debug
sync points, which is not the case after this patch. These tests are removed
by WL#6671 as well. An alternative is to port them to different storage engine.

.result file update for --embedded test run.

Issue:
======
Currently the approach we take to find the chunk corresponding to a given
pointer uses srv_buf_pool_chunk_unit based on the assumption that
srv_buf_pool_chunk_unit is the total size of all pages in a buffer pool
chunk. We first step back by srv_buf_pool_chunk_unit bytes and use
std::map::upper_bound() to find the first chunk in the map whose key >= the
resulting pointer.

However, the real size of a chunk (and thus, the total size of its pages)
may differ from the value configured with innodb_buffer_pool_chunk_size
due to rounding up to the OS page size. So, in some cases the above logic
gives us the wrong chunk.

Fix:
====
We find out the chunk corresponding to the give pointer without using
srv_buf_pool_chunk_unit. This is done by using std::map::upper_bound()
to find the next chunk in the map which appears right after the pointer and
decrementing the iterator, which would give us the chunk the pointer
belongs to.

This also is Linux only so corrected the cmake macro.

Fixed indenting in cmake macro.

Removed NUMA defination from include/my_config.h as its only

Clean-up nolock.h: it doesn't serve any purpose anymore. Appropriate code moved
to x86-gcc.h and my_atomic.h.

If gcc sync bultins were detected, we want to make use of them independently of
__GNUC__ definition. E.g. XLC simulates those, but doesn't define __GNUC__.

HS/Spider: According to AIX manual alloca() returns char*, which cannot be
casted to any type with static_cast. Use explicit cast instead.

MDL: Removed namemangling pragma, which didn't let MariaDB build with XLC.

WSREP: _int64 seem to be conflicting name with XLC, replaced with _integer64.

CONNECT: RTLD_NOLOAD is GNU extention. Removed rather meaningless check if
library is loaded. Multiple dlopen()'s of the same library are permitted,
and it never gets closed anyway. Except for error, which was a bug: it may
close library, which can still be referenced by other subsystems.

InnoDB: __ppc_get_timebase() is GNU extention. Only use it when __GLIBC__ is
defined.

2.Check the compressed algorithm.

The control file contents must be correct from the start and cannot
be modified at build time by CMake. Also all static Debian package
analyzers will fail to see all manipulations by CMake later on.

It is best to do all manipulations like these in autobake-deb.sh.

On systems with unix socket authentication root could run these
without any special maintenance accounts.

This will increase the speed of the build by a minute or two.

The build must stay under the Travis-CI 50 minute limit. Currently
they often exceed, and the huge test suite is the single most long
step in moving/packaging files, so remove it on Travis-CI automatically.

Also sort control file slightly to be easier to compare to downstream
control file and include gdb for automatic backtraces if the test suite
fails.

Delete duplicate man page installation.

Make mariadb-test breaks/replaces mariadb-server-5.5

Buildbot tries to create database 'test' so we need to have these
Debian-only exceptions enabled and patch our own source at build time.

This version of Debian packaging does not yet install systemd scripts,
so revert that part to the CMakeLists.txt based hack.

For Debian the rules file is the main makefile and assuming that a upstream
makefile will mangle the Debian packaging files creates false alerts
from static analysis tools and other problems.
