Truncate the maximum result length (64-bit wide type) to fit into
the item maximum length (32-bit wide type). This is possible as
this specific branch is only used if the maximum result length
is less than 0x1000000 (MAX_BLOB_WIDTH), which fits comfortably
in a 32-bit wide type.

WIN32 compilation fixes: define ETIMEDOUT only if not available and
fix typos and add a missing parameter.

From a user perspective, the problem is that a FLUSH LOGS or SIGHUP
signal could end up associating the stdout and stderr to random
files. In the case of this bug report, the streams would end up
associated to InnoDB ibd files.

The freopen(3) function is not thread-safe on FreeBSD. What this
means is that if another thread calls open(2) during freopen()
is executing that another thread's fd returned by open(2) may get
re-associated with the file being passed to freopen(3). See FreeBSD
PR number 79887 for reference:

  http://www.freebsd.org/cgi/query-pr.cgi?pr=79887

This problem is worked around by substituting a internal hook within
the FILE structure. This avoids the loss of atomicity by not having
the original fd closed before its duplicated.

Patch based on the original work by Vasil Dimov.

include/my_sys.h:
  Export my_freopen.
mysys/my_fopen.c:
  Add a my_freopen abstraction to workaround bugs in specific OSes.
  Add a prototype for getosreldate() as older FreeBSD versions did
  not define one.
sql/log.cc:
  Move freopen abstraction code over to mysys.
  The streams are now only reopened for writing.

   Basically take care that disconnects are finished.

- Second scenario checked:
  Ensure via wait routines that the commit comes after the
  processing of the statement which should get finally
  the ER_LOCK_WAIT_TIMEOUT
  --> This should prevent the current bug.
- First scenario checked:
  Ensure via wait routines that the statement is already waiting
  for getting the lock before the commit is given.
  --> No effect on the current bug, but ensure that the right
      scenario is reached.
- Take care that disconnects are finished before the test ends.
  --> Reduce the potential to harm succeeding tests.
- "Mangle" the printout of the current default innodb_lock_wait_timeout value
  --> No need to adjust the test in case the default gets changed in future.

   - remove the superfluous file
   - add an preemptive removal of the outfile before the
     SELECT ... INTO OUTFILE ...
2. Remove an already disabled subtest
   It's functionality is covered by tests in the suite funcs_1.
3. Adjust the formatting within some sub testcase to the formatting used
   in all other sub testcases

This assert could be triggered if -1 was inserted into
an auto increment column by a statement writing more than
one row.

Unless explicitly given, an interval of auto increment values
is generated when a statement first needs an auto increment
value. The triggered assert checks that the auto increment
counter is equal to or higher than the lower bound of this
interval.

Generally, the auto increment counter starts at 1 and is
incremented by 1 each time it is used. However, inserting an
explicit value into the auto increment column, sets the auto
increment counter to this value + 1 if this value is higher
than the current value of the auto increment counter.

This bug was triggered if the explicit value was -1. Since the
value was converted to unsigned before any comparisons were made,
it was found to be higher than the current vale of the auto
increment counter and the counter was set to -1 + 1. This value
was below the reserved interval and caused the assert to be
triggered the next time the statement tried to write a row.

With the patch for Bug#39828, this bug is no longer repeatable.
Now, -1 + 1 is detected as an "overflow" which causes the auto
increment counter to be set to ULONGLONG_MAX. This avoids hitting
the assert for the next insert and causes a new interval of
auto increment values to be generated. This resolves the issue.

This patch therefore only contains a regression test and no code
changes. Test case added to auto_increment.test.

Fixed the test case to be independent of build options used.
Removed the lowercase-table-names constraint, since performance schema tables are now in lowercase.

so will be run only weekly; this closes BUG#50595.

      
mysqlbinlog only prints "use $database" statements to its output stream
when the active default database changes between events. This will cause
"No Database Selected" error when dropping and recreating that database.
      
To fix the problem, we clear print_event_info->db when printing an event
of CREATE/DROP/ALTER database statements, so that the Query_log_event
after such statements will be printed with the use 'db' anyway except
transaction keywords.

ASSERT happens due to improper calculation of the max_length
in Item_func_div object, if dividend has max_length == 0 then
Item_func_div::max_length is set to 0 under some circumstances.
The fix:
If decimals == NOT_FIXED_DEC then set
Item_func_div::max_length to max possible
DOUBLE length value.

BUG #59055: RQG was broken after the checkin that removed rpl and rpl_ndb suites. RQG uses MTR V1 and that still has these in the default suite. Removing these from V1. Also removing references to ndb tests in some more disabled.def files

Problem: master executed a statement that would fail on slave
(namely, DROP USER 'create_rout_db'@'localhost').
Then the test did:
  --let $rpl_only_running_threads= 1
  --source include/rpl_reset.inc
rpl_reset.inc calls rpl_sync.inc, which first checks which of
the threads are running and then syncs those threads that are
running. If the SQL thread fails after the check, the sync will
fail. So there was a race in the test and it failed on some
slow hosts.
Fix: Don't replicate the failing statement.
