- Change the default flag value to ON.
- Update the testcases to be run extended_keys=ON:
  = trivial test result updates
  = If extended_keys setting makes a difference for a testcase, run the testcase 
    with extended_keys=off. There were only a few such cases
- Update to vcol_select_innodb looks like a worse plan but it will be gone in 10.0.

As part of the fix we don't anymore generate a create table statement when doing a
CREATE TABLE IF NOT EXISTS table_that_exist LiKE temporary_table
if the 'table_that_exist' existed.

This is because it's not self evident if we should generate a create statement
matching the existing table or the temporary_table. 
The old code generated a table like the existing table in row based replication and like the temporary table
in statement based replication.
It's better to ensure that both cases works the same way.

  Updated results

update_used_tables for the the where condition to update cached
indicators of constant subexpressions. It should be done before further
possible simplification of the where condition.

This change caused simplification of the executed where conditions 
in many test cases.

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().

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.

- Item_direct_view_ref didn't clear its pointer to item_equal in ::cleanup.
- Some Item_direct_view_ref objects have statement lifetime (i.e. they
  survive across multiple EXECUTE commands). Item_equal objects live only for
  the duration of one EXECUTE. This caused Item_direct_view_ref to have a stale pointer,
  which could cause all sorts of effects. (In this bug's testcase it was pointing to
  the wrong Item_equal, causing wrong query result)
- Fixed by doing what Item_field::cleanup() does - don't keep item_equal pointer value.
- There is no testcase because the only testcase I've got is highly fragile (e.g. the
  bug will not show up if @@datadir is of the wrong length).

This is port of fix for MySQL BUG#17647863.

  Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM

  Rename test() macro to MY_TEST() to avoid conflict with libc++.

Fixed so the MYSQL_TYPE_GEOMETRY is treated as BLOB.

The result is EMPTY for a buffer(line, -1), but we still
need one FALSE operation to be stored in the condition.
And we actually add it but forgot to alloc memory to store it.

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.
