fail CREATE SERVER foreign data wrapper is "mysql"
and neither HOST nor SOCKET are specified.

Also default PORT to 3306 (again, only for foreign
data wrapper "mysql")

* pass LEX_STRING's from the parser, don't ignore the length only to strlen later
* init LEX::server_options only for SERVER commands, not for every statement
* don't put temporary values into a global persistent memroot

but really it's just scratching a surface

otherwise mysqltest complains "No queries executed but non-empty result file found!"

in particular, not fail with --vertical_results

Problem was that temporal buffers allocated for page compression
are not initialized and rest of the page that is actually writen
was als not initialized after previous usage.

There was a race. The test case was expecting the slave to start processing a
particular DELETE statement, then the test would stop the slave at this
point. But there was missing something to wait until the slave would actually
reach this point; thus depending on timing it was possible that the slave
would be stopped too early, causing .result file difference.

Fixed by adding an appropriate wait to the test case.

Fix wording in error log message, to be consistent with other messages ("IO thread" -> "I/O thread").

Fix rare failures in test case rpl.rpl_gtid_basic:

 - Add another possible error code when a connection is killed.

 - Make sure that the IO thread has had time to complete its stop after START
   SLAVE UNTIL. Otherwise, START SLAVE might run before IO thread stop,
   leaving the test case with a stopped IO thread that eventually causes a
   wait timeout.

Decision about algorihtm moved on prepare phase.
Made possible to add mpore password algorithms.

Change constant with a system variable.

There was a race, a small window between updating slave position and updating
Seconds_Behind_Master, during which the test case could see the wrong value.

Fix by waiting for the expected status to appear.

Add support for semi-join strategies: FirstMatch, DuplicateWeedout,
LooseScan.

If we didn't do it, SJ-Materialization table would appear to
EXPLAIN JSON code as having different keyparts than it actually
has. This caused unpredictable content in "used_key_parts"

- Do set nest_level and nest_level_base for fake_select_lex objects.

- Switch Explain data structure from "flat" representation of
  SJ-Materialization into nested one.
- Update functions that print tabular output to operate on the
  nested structure.
- Add function to generate JSON output.

local function variable was overwriting the global one.
also remove unused variable expansion.

control scripts (mysqld_safe for example) want to know
whether a recovery was successful or not.
total silence is too suspicious to be trusted.

MDEV-7188 main.signal_demo3 and sys_vars.max_sp_recursion_depth_func fail in biuldbot on labrador with Thread stack overrun

reduce stack requirememnts for CALL by just a little bit

Added Rows_affected to slow query log & mysql.slow_log table.
