031f11717d Fix all warnings given by UBSAN
The easiest way to compile and test the server with UBSAN is to run:
./BUILD/compile-pentium64-ubsan
and then run mysql-test-run.
After this commit, one should be able to run this without any UBSAN
warnings. There is still a few compiler warnings that should be fixed
at some point, but these do not expose any real bugs.

The 'special' cases where we disable, suppress or circumvent UBSAN are:
- ref10 source (as here we intentionally do some shifts that UBSAN
  complains about.
- x86 version of optimized int#korr() methods. UBSAN do not like unaligned
  memory access of integers.  Fixed by using byte_order_generic.h when
  compiling with UBSAN
- We use smaller thread stack with ASAN and UBSAN, which forced me to
  disable a few tests that prints the thread stack size.
- Verifying class types does not work for shared libraries. I added
  suppression in mysql-test-run.pl for this case.
- Added '#ifdef WITH_UBSAN' when using integer arithmetic where it is
  safe to have overflows (two cases, in item_func.cc).

Things fixed:
- Don't left shift signed values
  (byte_order_generic.h, mysqltest.c, item_sum.cc and many more)
- Don't assign not non existing values to enum variables.
- Ensure that bool and enum values are properly initialized in
  constructors.  This was needed as UBSAN checks that these types has
  correct values when one copies an object.
  (gcalc_tools.h, ha_partition.cc, item_sum.cc, partition_element.h ...)
- Ensure we do not called handler functions on unallocated objects or
  deleted objects.
  (events.cc, sql_acl.cc).
- Fixed bugs in Item_sp::Item_sp() where we did not call constructor
  on Query_arena object.
- Fixed several cast of objects to an incompatible class!
  (Item.cc, Item_buff.cc, item_timefunc.cc, opt_subselect.cc, sql_acl.cc,
   sql_select.cc ...)
- Ensure we do not do integer arithmetic that causes over or underflows.
  This includes also ++ and -- of integers.
  (Item_func.cc, Item_strfunc.cc, item_timefunc.cc, sql_base.cc ...)
- Added JSON_VALUE_UNITIALIZED to json_value_types and ensure that
  value_type is initialized to this instead of to -1, which is not a valid
  enum value for json_value_types.
- Ensure we do not call memcpy() when second argument could be null.
- Fixed that Item_func_str::make_empty_result() creates an empty string
  instead of a null string (safer as it ensures we do not do arithmetic
  on null strings).

Other things:

- Changed struct st_position to an OBJECT and added an initialization
  function to it to ensure that we do not copy or use uninitialized
  members. The change to a class was also motived that we used "struct
  st_position" and POSITION randomly trough the code which was
  confusing.
- Notably big rewrite in sql_acl.cc to avoid using deleted objects.
- Changed in sql_partition to use '^' instead of '-'. This is safe as
  the operator is either 0 or 0x8000000000000000ULL.
- Added check for select_nr < INT_MAX in JOIN::build_explain() to
  avoid bug when get_select() could return NULL.
- Reordered elements in POSITION for better alignment.
- Changed sql_test.cc::print_plan() to use pointers instead of objects.
- Fixed bug in find_set() where could could execute '1 << -1'.
- Added variable have_sanitizer, used by mtr.  (This variable was before
  only in 10.5 and up).  It can now have one of two values:
  ASAN or UBSAN.
- Moved ~Archive_share() from ha_archive.cc to ha_archive.h and marked
  it virtual. This was an effort to get UBSAN to work with loaded storage
  engines. I kept the change as the new place is better.
- Added in CONNECT engine COLBLK::SetName(), to get around a wrong cast
  in tabutil.cpp.
- Added HAVE_REPLICATION around usage of rgi_slave, to get embedded
  server to compile with UBSAN. (Patch from Marko).
- Added #ifdef for powerpc64 to avoid a bug in old gcc versions related
  to integer arithmetic.

Changes that should not be needed but had to be done to suppress warnings
from UBSAN:

- Added static_cast<<uint16_t>> around shift to get rid of a LOT of
  compiler warnings when using UBSAN.
- Had to change some '/' of 2 base integers to shift to get rid of
  some compile time warnings.

6378c95ee0 Fix that end_bulk_insert() doesn't write to to-be-deleted files
This affected mainly MyISAM and Aria engines.
Also fixed that end_bulk_insert() detects errors from
internal mi_end_bulk_insert() and ma_end_bulk_insert()

- delete_tree() and delete_tree_element() now has an
  extra argument that marks if future calls to
  tree->free should be ignored.
- tree->free changed to function returning int, to be
  able to signal errors.
- Restored deleting flag in MyISAM that was accidently
  disabled in mi_extra(PREPARE_FOR_DROP)

a260b15554 MDEV-4011 Added per thread memory counting and usage
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,...)

d01b5c392c Bug#11757464:SERVER CRASH IN RECURSIVE CALL WHEN OOM
Analysis:
---------

When the server is out of memory, an error is raised
to indicate the same. Handling the error requires
more memory to be allocated which fails, hence the
error handling loops in a recursion and causes the
server to crash.

Fix:
---
a) Prevents pushing the 'out of memory' error condition
to the diagnostic area as it requires memory allocation.
GET DIAGNOSTICS, SHOW WARNINGS and SHOW ERRORS statements
will not show information about this error. However the
'out of memory' error is returned to the client.
b) It sets the ME_FATALERROR flag when 'out of memory' errors
are reported (for places where the flag is not already set).
This flag prevents activation of SP error handlers which also
require memory allocation and therefore are likely to fail.

ecbcddc03d Improved speed of thr_alarm from O(N) to O(1). thr_alarm is used to handle timeouts and kill of connections.
Fixed compiler warnings.
queues.h and queues.c are now based on the UNIREG code and thus made BSD.
Fix code to use new queue() interface. This mostly affects how you access elements in the queue.
If USE_NET_CLEAR is not set, don't clear connection from unexpected characters. This should give a speed up when doing a lot of fast queries.
Fixed some code in ma_ft_boolean_search.c that had not made it from myisam/ft_boolean_search.c


include/queues.h:
  Use UNIREG code base (BSD)
  Changed init_queue() to take all initialization arguments.
  New interface to access elements in queue
include/thr_alarm.h:
  Changed to use time_t instead of ulong (portability)
  Added index_in_queue, to be able to remove random element from queue in O(1)
mysys/queues.c:
  Use UNIREG code base (BSD)
  init_queue() and reinit_queue() now takes more initialization arguments. (No need for init_queue_ex() anymore)
  Now one can tell queue_insert() to store in the element a pointer to where element is in queue. This allows one to remove elements from queue in O(1) instead of O(N)
mysys/thr_alarm.c:
  Use new option in queue() to allow fast removal of elements.
  Do less inside LOCK_alarm mutex.
  This should give a major speed up of thr_alarm usage when there is many threads
sql/create_options.cc:
  Fixed wrong printf
sql/event_queue.cc:
  Use new queue interface()
sql/filesort.cc:
  Use new queue interface()
sql/ha_partition.cc:
  Use new queue interface()
sql/ha_partition.h:
  Fixed compiler warning
sql/item_cmpfunc.cc:
  Fixed compiler warning
sql/item_subselect.cc:
  Use new queue interface()
  Removed not used variable
sql/net_serv.cc:
  If USE_NET_CLEAR is not set, don't clear connection from unexpected characters.
  This should give a speed up when doing a lot of fast queries at the disadvantage that if there is a bug in the client protocol the connection will be dropped instead of being unnoticed.
sql/opt_range.cc:
  Use new queue interface()
  Fixed compiler warnings
sql/uniques.cc:
  Use new queue interface()
storage/maria/ma_ft_boolean_search.c:
  Copy code from myisam/ft_boolean_search.c
  Use new queue interface()
storage/maria/ma_ft_nlq_search.c:
  Use new queue interface()
storage/maria/ma_sort.c:
  Use new queue interface()
storage/maria/maria_pack.c:
  Use new queue interface()
  Use queue_fix() instead of own loop to fix queue.
storage/myisam/ft_boolean_search.c:
  Use new queue interface()
storage/myisam/ft_nlq_search.c:
  Use new queue interface()
storage/myisam/mi_test_all.sh:
  Remove temporary file from last run
storage/myisam/myisampack.c:
  Use new queue interface()
  Use queue_fix() instead of own loop to fix queue.
storage/myisam/sort.c:
  Use new queue interface()
storage/myisammrg/myrg_queue.c:
  Use new queue interface()
storage/myisammrg/myrg_rnext.c:
  Use new queue interface()
storage/myisammrg/myrg_rnext_same.c:
  Use new queue interface()
storage/myisammrg/myrg_rprev.c:
  Use new queue interface()
