Put client plugins into -common rpm, not -shared.
Because they're needed for
* all clients that link with shared libmysqlclient (-shared)
* our clients from -client rpm, they're statically linked (-client)
* the server that acts as a replication slave (-server)

MDEV-7871 Tests fail massively on "Assertion `status_var.memory_used == 0'" when run with --ps --embedded.
   As the MF_THREAD_SPECIFIC was introduced to the alloc_root's and
   the prealloc added to the statement::mem_root and statement::result.alloc, we have to adjust
   the embedded server to it. The preallocation was removed for the embedded server as it
   makes no sence for it. The msyqltest should free the statement inside the proper thead to
   make the memory statistics happy.

MDEV-8131 MariaDB does not build on hurd-i386: plugin/auth_dialog/dialog.c:172:20: error: 'RTLD_DEFAULT' undeclared

define _GNU_SORUCE before including dlfcn.h

when --bind-address is not specificed explicitly (or set to '*')
MariaDB tries all wildcard addresses. Print a warning (not an error)
if a socket cannot be created for some of them.

Still print an error if a socket cannot be created for an address
that a user has specified expicitly with --bind-address.

disable IPv6 globally in mysql-test, only use it
in dedicated IPv6 tests (where it is enabled per-test)

in the previous commit for MDEV-8205.

MDEV-8316: debugger aborting because missing DBUG_RETURN or DBUG_VOID_RETURN macro in function "any_slave_sql_running"

Fix a handful of "return" that should be DBUG_RETURN in sql/rpl_mi.cc.

Follow-up patch to temporarily avoid a sporadic failure in the test
rpl.rpl_000011 due to MDEV-8301.

There is a window during thread exit where the global status is
counted incorrectly - the contribution for the exiting thread is
counted twice. The patch for MDEV-8294 made this window visible to the
test case rpl.rpl_000011, causing it to sporadically fail. Temporarily
silence this with a wait for the expected value; can be removed once
MDEV-8294 is fixed.

MDEV-8212 alter table - failing to ADD PRIMARY KEY IF NOT EXISTS when existing index of same as column name.
        The default name for the primary key is rather 'PRIMARY' instead of the indexed column name.

Add progress info on InnoDB/XtraDB row0merge phase. Note that we
do not know exact number of rounds merge sort needs at start thus
also progress report might not be accurate.

#include <m_string.h> where strnlen() is used

Added test case to show that correct error message is printed when
log file size is too small for big blob.

some duplicate code.

* take into account that example may be NULL
* use example->safe_charset_converter(), copy-paste from
  Item::safe_charset_converter() (example might have its own
  implementation)
* handle the case when the charset doesn't need conversion
  (and return this).

There were some cases where the slave SQL thread could stop without
the pool of parallel replication worker threads being correctly
de-activated.

* add a test when server certificate is verified successfully
* one test with two combinations (instead of two tests)
* verbose tets: make it print what it is doing
* fix the test to work with yassl and no-ssl builds

            keys

Fixed that OPTIMIZE TABLE against MyISAM/Aria table may write uninitialized key
root position for disabled keys.

           semisync plugin and setting rpl_semi_sync_master_enabled

There was race condition between INSTALL PLUGIN and SET. It was caused by a
gap in INSTALL PLUGIN when plugin variables were registered but not fully
initialized. Accessing such variables concurrently may reference uninitialized
memory, specifically sys_var_pluginvar::plugin.

Fixed by initializing sys_var_pluginvar::plugin early, before variable is
registered.

           semisync plugin and setting rpl_semi_sync_master_enabled

Cleanup:
Removed my_intern_plugin_lock() and my_intern_plugin_lock_ci() wrappers. They
were obsoleted by revision f56dd32b.

instead of running them only when ssl is not compiled in

"Range Checked for Each Record" should be only employed when the other
option would be cross-product join (i.e. the other option is so bad that
we hardly risk anything).

Previous logic was: use RCfER if there are no possible quick selects, or
quick select would read > 100 rows. Also, it didn't always work as
expected due to range optimizer changing table->quick_keys and us
looking at sel->quick_keys.

Another angle is that recent versions have enabled use of Join Buffering
in e.g. outer joins. This further reduces the range of cases where RCfER
should be used.

We are still unable to estimate the cost of RCfER with any precision, so
now changing the condition of "no quick select or quick->records> 100"
to a hopefully better condition "no quick select or quick would cost more
than full table scan".

Using --ssl-verify-server-cert and --ssl[-*] implies that
the ssl connection is required. The mysql client will now print an error if ssl
is required, but the server can not handle a ssl connection.

MDEV-7695 MariaDB - ssl - fips: can not connect with --ssl-cipher=DHE-RSA-AES256-SHA - handshake failure

Change 512bit DH key to 1024bit to meet FIPS requirements

Changing the error message to:
 "...from type 'decimal(0,?)/*old*/' to type ' 'decimal(10,7)'..."
So it's now clear that the master data type is OLD decimal.

Removing Item_cache::used_table_map, Item_cache::used_tables() and
Item_cache::set_used_tables(). Using the same inherited from
Item_basic_constant implementations instead.
