update all start_bulk_insert() methods to the new signature.

libmysqld/lib_sql.cc:
  * don't overwrite my_progname in embedded
  * this memroot is sometimes freed by the caller, outside of THD context
mysql-test/t/user_var.test:
  typo: duplicate line

* don't use 'myf flags', when 'my_bool is_thread_specific' is meant
* call set_malloc_size_cb() for embedded too
* warn in safemalloc if the memory is freed by a wrong thread

sql/mysqld.cc:
  move set_malloc_size_cb() to a function that is also called for embedded
sql/mysqld.h:
  gdb-friendly, one can put breakpoint on a function, but not on a macro
sql/sql_class.cc:
  initialize thread_id earlier

* remove unused mysql_option
* don't allocate 5GB of memory in the mtr tests
* restore the behavior in dynamic_column_offset_byte(), put the ifdef correctly
* prefer __attribute__((unused)) to #ifdef
* prefer UNINIT_VAR to LINT_INIT
* make most Warning_info users blissfully unaware of the postponed initialization
* use my_offsetof instead of offsetof where the compiler thinks the latter is incorrect

as only my_init_dynamic_array and my_init_dynamic_array2 are used everywhere.
fix ha_cassandra to compile.

Base code and idea from a patch from by plinux at Taobao.

The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC.
Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc().
There are plenty of new asserts to ensure that for a debug server the counting is correct.

Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS.
- The later is there mainly to show how query is progressing.

The following changes in interfaces was needed to get this to work:
- init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
- One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root()
- my_init_dynamic_array()  has extra option so that one can mark memory with MY_THREAD_SPECIFIC
- my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
- Added flag for hash_init() so that one can mark hash table to be thread specific.
- Added flags to init_tree() so that one can mark tree to be thread specific.
- Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG.
- Added flag to Warning_info::Warning_info() if the structure should be fully initialized.
- String elements can now be marked as thread specific.
- Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC.
- Changed type of myf from int to ulong, as this is always a set of bit flags.

Other things:
- Removed calls to net_end() and thd->cleanup() as these are now done in ~THD()
- We now also show EXAMINED_ROWS in SHOW PROCESSLIST
- Added new variable 'memory_used'
- Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory.
- Removed calls to the obsoleted function init_dynamic_array()
- Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...)

The bug could cause a crash when several connections needed
persistent statistics for the same table.

Also added a missing call of set_statistics_for_table() in the code

Backport the fix from 10.0 tree

- The problem was that thd_killed() may be called by innodb from 
  an internal innodb thread.
- Fixed by not processing APC requests when we're not in the thread
  that owns the APC target.

Field matching fixed.
DBUG_ASSERT fixed.

Made allocation of memory for statistical data in a table share to be thread safe.
This memory is now allocated in a special MEM_ROOT that is created for each
table share.  

Remove timed mutexes in XtraDB - obsolete feature that does not link on Windows, if plugin is build dynamically
It was already  removed from innobase in the past.

Reasons:
  - as of 5.5.27, YEAR(2) is deprecated, hence the new warning;
  - MDEV-553 - different error code/message on out-of-range autoincrement;
  - INSERT IGNORE now produces a warning if a duplicate was encountered

storage_engine tests and upstream engines/* suites went out of sync with current MariaDB code. Reasons:
  - as of 5.5.27, YEAR(2) is deprecated, hence the new warning;
  - MDEV-553 - different error code/message on out-of-range autoincrement;
  - INSERT IGNORE now produces a warning if a duplicate was encountered (change pushed along with MDEV-553)

- update ha_cassandra::start_bulk_insert() definition to match those in class handler.
