mysql_derived_prepare() was executed on the statement memory.
Now it is executed on the runtime memory.
All bugs induced by this were fixed.

Fix for MDEV-6493: Assertion `table->file->stats.records > 0 || error' failure, or 'Invalid write' valgrind warnings, or crash on scenario with Aria table, view, LOCK TABLES

This bug only happens in case of paritioned tables used in LOCK TABLES and implicit_commit() was called
(as part of trying to execute a CREATE TABLE withing lock tables)

The problem was that Aria could not move the tables from one transaction to the new one, as thd->open_tables contained
a partitioned tables and not an Aria table.

Fix:
- Store a list of all open tables that are part of a share in share->open_tables
- In maria::implict_commit() use transaction->used_tables & share->open_tables to find out which tables
  was part of the current transaction instead of using thd->open_tables, which may contain partitioned tables.


mysql-test/suite/maria/maria_partition.result:
  Added test case
mysql-test/suite/maria/maria_partition.test:
  Added test case
storage/maria/ha_maria.cc:
  Use trn->used tables and share->open_tables to find out which tables was part of the current transaction instead of using thd->open_tables.
storage/maria/ma_close.c:
  Remove closed table from share->open_list
storage/maria/ma_open.c:
  Add table to share->open_list
storage/maria/ma_state.c:
  Added comment
storage/maria/maria_def.h:
  Added share->open_list, a list of all tables that is using this share.

* remove incorrect assertion (it didn't take into account concurrent clients)
* fix the comment

Free the trx of the current thd (if any) in innobase_end()

  
- adjusted a test result according to the change made for MDEV-6100;
- added explicit timezone for engines/iuds, since MTR in
  MariaDB does not set it like MySQL's, and tests with constant TIMESTAMP
  can have different outcome

MDEV-6082 Assertion `0' fails in TC_LOG_DUMMY::log_and_order on DML after installing TokuDB at runtime on server with disabled InnoDB

We don't support changing tc_log implementation at run time.
If the first XA-capable engine is loaded with INSTALL PLUGIN - disable its

abort the wait loop if mysqld_safe is not running

and

InnoDB: Assertion failure in thread 2868898624 in file buf0lru.c line 1077
InnoDB: Failing assertion: mutex_own(&buf_pool->LRU_list_mutex)

Analysis: Function buf_LRU_free_block might release LRU_list_mutex on
same cases to avoid mutex order problems, we need to take it back 
before accessing list. 

backport from 10.0 the fix for:

MySQL Bug#71095: Wrong results with PARTITION BY LIST COLUMNS()

- Backprot the fix from MySQL Bug#71095.

- When traversing JOIN_TABs with first_linear_tab/next_linear_tab(), don't forget
  to enter the semi-join nest when it is the first table in the join order.
  Failure to do so could cause e.g. I_S tables not to be filled.

Item_func_min_max::get_date() did not clear ltime->year when returning a TIME value.

            server initialization

ER() macro was used during server initialization. It refers to
current_thd, which is not available that early.

Print error to error log in "lc-messages" locale.
Avoid duplicate error message during server initialization.

mysqld didn't fail to start if a compiled-in plugin failed to initialize

Improve long semaphore wait output to include all semaphore waits
and try to find out if there is a sequence of waiters.

Add more status information if repeatable.

- Part #2. Fix obvious problems in the previous patch.

- Filesort has an optmization where it reads only columns that are 
  needed before the sorting is done.
- When ref(_or_null) is picked by the join optimizer, it may remove parts
  of WHERE clause that are guaranteed to be true.
- However, if we use quick select, we must put all of the range columns into the 
  read set. Not doing so will may cause us to fail to detect the end of the range.

Analysis: sync array output function, should make sure that all 
used pointers are valid before using them.

This is not a real fix, instead try to gather additional information
at the point when dictionary content is not what we expect it to be.

  than with InnoDB plugin
  
  Fix: os0file.h in XtraDB had OS_AIO_N_PENDING_IOS_PER_THREAD 256
  when on InnoDB it is OS_AIO_N_PENDING_IOS_PER_THREAD 32. Changed
  XtraDB also to use 32.

  
  Analysis: Based on crashed the buffer pool instance identifier is
  not correct on block to be freed. Add LRU list mutex holding
  on functions calling free and add additional safety checks.

That particular part of slave connect to master was missing code to handle
retry in case of network errors. The same problem is present in MySQL 5.5, but
fixed in MySQL 5.6.

Fixed with this patch, by adding the code (mostly identical to MySQL 5.6), and
also adding a test case.

I checked other queries done towards master during slave connect, and they now
all seem to handle reconnect in case of network failures.

Fix an error case where success was returned instead of error.
