The patch also fixes a race in rpl_stop_slave.test.

On machines with lots of CPU and memory, something like `mtr --parallel=10`
can speed up the test suite enormously. However, we have a few test cases
that run for long (several minutes), and if we are unlucky and happen to
schedule those towards the end of the test suite, we end up with most
workers idle while waiting for the last slow test to end, significantly
delaying the finish of the entire suite.

Improve this by marking the offending tests as taking "long", and trying
to schedule those tests early. This reduces the time towards the end of
the test suite run where some workers are waiting with nothing to do for
the remaining workers each to finish their last test.

Also, the rpl_stop_slave test had a race which could cause it to take
a 300 seconds debug_sync timeout; this is fixed.

Testing on a 4-core 8GB machine, this patch speeds up the test suite with
around 30% for --parallel=10 (debug build), allowing to run the entire
suite in 5 minutes.

don't fill in handlerton::commit member, as it's not used
and makes MySQL believe that Aria is transactional.
Fix the TRANSACTIONAL=1 warning.

When the optimizer creates items out of other items it does
not have to call the fix_fields method. Usually in these
cases it calls quick_fix_field() that just marks the 
created item as fixed. If the created item is an Item_func
object then calling quick_fix_field() works fine if the
arguments of the created functional item are already fixed.
Otherwise some unfixed nodes remain in the item tree and
it triggers an assertion failure whenever the item is 
evaluated.

Fixed the problem by making the method quick_fix_field
virtual and providing an implementation for the class
Item_func objects that recursively calls the method
for unfixed arguments of any functional item.

BUILD/compile-pentium64:

  We need to flush blob pages to disk to ensure they overwrite any reused head/tail pages.

set thd->password appropriately also for cases when a user was not found.

It was missing from EXTRA_DIST in Makefile.am.

(Includes patch for overrun detected by valgrind thanks to previous my_alloca() -> my_malloc() patch)

mysys/thr_lock.c:
  Fixed typo that caused compile failure

- This allows us to detect missing my_afree() calls and also find overruns (when running with valgrind) to alloca() areas.
- Added missing my_afree() calls
- Fixed wrong call to my_afree()


include/my_sys.h:
  When compiling with valgrind, change my_alloca() to use my_malloc()
mysql-test/suite/innodb/t/innodb_bug57255.test:

storage/maria/ma_check.c:
  Allocate also memory for nodflag and transid's
storage/maria/ma_write.c:
  Allow nodflag and transid as part of key.
  (This has nothing to do with the bug report, but it's a safer check).
storage/maria/maria_def.h:
  Define MARIA_MAX_POINTER_LENGTH (length of pointer to node)
  Added node pointer length to MARIA_INDEX_OVERHEAD_SIZE, as this is part of the key.
  (Safety fix)

Made archive.test a bit more safe

MBug#687320: Fix sporadic test failures in innodb_mysql.test and partition_innodb_semi_consistent.test

Problem is that these tests run with --innodb-lock-wait-timeout=2 in .opt
(and this is necessary as built-in innodb does not allow to change this
dynamically). This cases another part of the test to occasionally time
out an UPDATE, which subsequently caused the test case to timeout due to
waiting for a condition (successful UPDATE) that never occurs.

Fixed by re-trying the update in case of timeout.

Tested by inserting a sleep() in the connection that the UPDATE is waiting
for, and checking that the retry loops a couple of times until the other
connection is done and COMMITs.

the same execution plan that is in the output of the corresponding
EXPLAIN.

Problem : mtr reports test failure because it sees
[ERROR] mysqld got exception 0x80000003 ;
in the .err file

The exception comes from DBUG_EXECUTE_IF (.. abort())

Fix:  use DBUG_ABORT instead of abort() - it does not throw 
any exceptions.

The reason for failure is that DBUG_EXECUTE_IF in mi_open()
only worked for Unix-formatted file names, due to strstr(name, "/crashed")

The fix change strstr() above to strstr(name, "crashed"), to it can work with 
Windows file names as well.

 
Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC
flag, while anything else is compiled with SAFEMALLOC.

As a consequence, my_hash_init used inside federatedx initialization does not
provide correct caller info parameters (file, line) , so they are initialized with 
whatever is on stack. When info about allocated memory is output in
COM_DEBUG command, the server crashes trying to output string starting at
0xcccccccccccccccc.

The fix is to remove SAFEMALLOC  preprocessor flags 
from every CMakeLists.txt, except the top-level one.

Also, SAFEMALLOC is not defined by default now, instead
there is WITH_DEBUG_FULL CMake option which adds 
-DSAFEMALLOC to C and C++ flags in debug compilation. 
This option is off by  default, because 
1) Debug C runtime already has heap debugging builtin with 
 overwrite and leak detection
2)safemalloc considerably slows down the tests.


Note also  that 
- SAFEMALLOC is gone  in MySQL5.5
- On Windows, heap related overflows can also be found using free pageheap utility
(that is also part of application verifier). This is even more efficient if there are no other layers 
on top of Windows heap allocator, e.g  it is most efficient with release version.

- Moved end_pagecache() to after maria_close()
- Flush page cache before closing files (in maria_pack)
Fixed test suite failure for PBXT

mysql-test/suite/pbxt/r/select.result:
  We mask out the 'rows' column because it may differ from run to run
mysql-test/suite/pbxt/t/select.test:
  We mask out the 'rows' column because it may differ from run to run
storage/maria/maria_chk.c:
  Moved end_pagecache() to after maria_close() to not trigger end-consistency testing of pagecache.
storage/maria/maria_pack.c:
  Moved end_pagecache() to after maria_close() to not trigger end-consistency testing of pagecache.
  flush page cache before closing files.

The assert removed because it do not take into account case when previous and this buffers used for first time but previous buffer was not sent to disk yet (i.e. previous buffer was never sent to disk yet).
