BUG#25712 - insert delayed and check table run together report
            crashed tables

Let MY_THREADSAFE have distinct value. Some functions call my_seek
passing MyFlags argument directly to it. This may cause unnecessary
locks, which may finally lead to a dead-lock (specifically see my_lock).

  Let MY_THREADSAFE have distinct value. Some functions call my_seek
  passing MyFlags argument directly to it. This may cause unnecessary

  Also it doesn't affect my_pread/my_pwrite in any way. So the comment was
  updated.

            tables

In case system doesn't have native pread/pwrite calls (e.g. Windows)
and there is CHECK TABLE runs concurrently with another statement that
reads from a table, the table may be reported as crashed.

This is fixed by locking file descriptor when my_seek is executed on
MyISAM index file and emulated pread/pwrite may be executed concurrently.

Affects MyISAM tables on platforms that do not have native
pread/pwrite calls (e.g. Windows).

No deterministic test case for this bug.


myisam/mi_check.c:
  Key file descriptor is shared among threads and mixed set of
  my_pread/my_pwrite and my_seek calls is possible. This is not
  a problem on systems that have native pread/pwrite calls.
  
  In case system doesn't have native pread/pwrite calls (e.g. Windows)
  we must ensure that my_pread/my_pwrite are not executed at the same
  time with my_seek. This is done by passing MY_THREADSAFE flag to
  my_seek.
mysys/my_seek.c:
  On platforms that do not have native pread/pwrite calls (e.g. Windows)
  these calls are emulated as follow: lock fd, lseek, read, unlock fd.
  
  In case file descriptor is shared among threads, where one thread
  executes my_pread and another thread executes my_seek, we may read
  from a wrong position. This may happen because my_seek doesn't lock
  fd and thus may be executed by another thread after emulated pread
  has done lseek and before it has done read.
  
  To fix problem mentioned above we introduce new flag MY_THREADSAFE to
  my_seek, which is meaningful only in case pread/pwrite calls are
  emulated. If this flag is set, lseek operation is performed as follow:
  lock fd, seek, unlock fd.

            can crash under load
Post-post-review fixes.
Fixed a typo == -> =
Optimized normal flush at end of statement (FLUSH_KEEP),
but let other flush types be stringent.
Added comments.
Fixed debugging.

 fixed coverage of out-of-mem errors

 - added join cache indication in EXPLAIN (Extra column).
 - prefer filesort over full scan over 
   index for ORDER BY (because it's faster).
 - when switching from REF to RANGE because
   RANGE uses longer key turn off sort on
   the head table only as the resulting 
   RANGE access is a candidate for join cache
   and we don't want to disable it by sorting
   on the first table only.

The LEAST/GREATEST functions compared DATE/DATETIME values as
strings which in some cases could lead to a wrong result.

A new member function called cmp_datetimes() is added to the
Item_func_min_max class. It compares arguments in DATETIME context
and returns index of the least/greatest argument.
The Item_func_min_max::fix_length_and_dec() function now detects when
arguments should be compared in DATETIME context and sets the newly
added flag compare_as_dates. It indicates that the cmp_datetimes() function
should be called to get a correct result.
Item_func_min_max::val_xxx() methods are corrected to call the
cmp_datetimes() function when needed.
Objects of the Item_splocal class now stores and reports correct original
field type.

When checking for applicability of join cache
we must disable its usage only if there is no
temp table in use.
When a temp table is used we can use join
cache (and it will not make the result-set 
unordered) to fill the temp table. The filesort() 
operation is then applied to the data in the temp 
table and hence is not affected by join cache
usage.
Fixed by narrowing the condition for disabling 
join cache to exclude the case where temp table
is used.
