In ::position() federated needs to know an element before the
current ("data_cursor") in the single-linked list. Replace list
traversal for every ::position() call (which is O(n^2)) with remembering
the current element before it's advanced by mysql_fetch_row().

Use 20-year ssl certificates for mysql-test from RedHat patch

On fedora:
1. provide/obsoleve mariadb-* packages
2. MariaDB-common conflicts with mariadb-libs (on filesystem level),
   but does not provide or obsolete it.

* readability fixes
* CPackRPM wrapper to fix property leakage between components (cmake bug 13248)

might end up having the same query id

An attempt to introduce libmysqlclient.so symbol versioning that is
compatible both with Debian and Fedora all versions: put all symbols into
libmysqlclient_18 version node (as on Debian), but also put aliases of
old symbols into libmysqlclient_16 version node (as on Fedora).

Also use a linker script to create aliases of exported symbols, not
rpm_support.cc source file.

Wait until the server starts accepting connections, not until the pid file appears

daemon plugin: join the thread to make sure it exits before the plugin is unloaded

It helps to interpret valgrind/safemalloc memory-related warnings that are
printed when a plugin is unloaded (and thus cannot resolve addresses automatically)

Handles the case of
sysctl net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1

don't include m_string. in my_valgrind.h

actually consumed it. With this patch evaluated query buffer is freed
along with query buffer.

The problem was uncovered by udf_debug_sync.test when it was run with
--embedded.

with Oracle's fix for Bug#17588348 by reverting Oracle's fix.

MDEV-5555: Incorrect index_merge on BTREE indices
- In ha_partition, make ordered index reads return rows in rowid order
  when index columns are the same.

(simply, copied from FederatedX)

  message:
    Enable rpl_row_create_table (no reason to keep this disabled anymore)

Still fails (in --ps), no reason to enable it if it is not fixed.

(just to have the test in the tree when we merge the upstream fix)

Don't ignore the error from st_select_lex_unit::optimize()

as it was supposed to be in bug#11747970, don't fake an error.
(this kill can be useful for other bugs too)

Deadlock happened due to mixed lock order.
CREATE/DROP function: wrlock(THR_LOCK_udf) -> lock(LOCK_open)
SELECT from view: lock(LOCK_open) -> rdlock(THR_LOCK_udf)

Fixed CREATE/DROP function so that LOCK_open does not intersect with
wrlock(THR_LOCK_udf).

10.0 is not affected: it doesn't hold LOCK_open while opening view.

(mainly by backporting 5.5. changes)

mysql-test/suite/maria/t/distinct.test:
  Remove the test that requires SSL. One test case for a bug is enough.

fix the NAME_CONST check to only allow literals, negated literals, and literals with
the explicit collation.

Fixed error processing in find_order_in_list(): if an error reported to user there is no sens to continue.

This is needed to be able to ignore executable comments from version 10.0.

Problem was that we used cache_table in some cases where it was not initialized
