message:
  fix for BUG#50120 "Valgrind errors in any test, inside mysqltest"
  Problem was that as v->name[v->name_len] may be uninitialized (which is ok per se),
  it shouldn't be used in an if(). We remove this zero_the_char/restore_it logic by
  rather zero-terminating the v->name string when we create it in var_init().

Subtraction of two unsigned months yielded a (very large) positive value.
Conversion of this to a signed value was not necessarily well defined.

Solution: do the subtraction on signed values.


mysql-test/r/events_scheduling.result:
  Add test case.
mysql-test/t/events_scheduling.test:
  Add test case.
sql/event_data_objects.cc:
  Convert month to signed before doing the subtraction.

eliminate 3 more "directory path" variables from the test's output (it was already
the case for other similar ones likes slow-query-log-file).

"set engine_condition_pushdown" is deprecated, engine condition pushdown is controlled
by a new "set optimizer_switch=engine_condition_pushdown=on|off".

fixing wrong indentation in two Makefile.am, which prevented the Anjuta IDE from parsing the MySQL tree.

           subquery in the select list
      
When a dependent subquery with count(distinct <col>) was 
evaluated multiple times, the Distinct_Aggregator was reused. 
However, the Aggregator was not reset, so when the subquery was
evaluated for the next record in the outer select, old dependent
info was used.
      
The fix is to clear() the existing aggregator in 
Item_sum::set_aggregator(). This ensures that the aggregator is
reevaluated with the new dependent information.

mysql-test/r/subselect3.result:
  Added test case for BUG#48920
mysql-test/t/subselect3.test:
  Added test case for BUG#48920
sql/item_sum.cc:
  If an aggregator exists when Item_sum::set_aggregator() is
  called (i.e., set_aggregator is called in a dependent
  subquery), the aggregator is reset so that the aggregator is
  reevaluated with the dependent information from the outer
  record being evaluated.

 
- backported code that handles %f/%g arguments in 
my_vsnprintf.c from 6.0 
- backported %f/%g tests in unittest/mysys/my_vsnprintf-t.c 
from 6.0 
- replaced snprintf("%g") in sql/set_var.cc with my_gcvt() 
- removed unnecessary "--replace-result"s for Windows in 
mysql-test/suite/sys_vars/t/long_query_time_basic.test 
- some test results adjustments

Backport Bug #43913  rpl_cross_version can't pass on conflicts complainig clash with --slave-load-tm

The 'rpl_cross_version' fails on mysql-next-mr-bugfixing as following:
mysqltest: In included file "./include/setup_fake_relay_log.inc": At line 80: query
'select './$_fake_filename-fake.000001\n' into dumpfile '$_fake_relay_index'' failed:
1290: The MySQL server is running with the --secure-file-priv option so it cannot execute
this statement.

To fix the problem by removeing the --secure-file-priv option
for adapting the update of the 'setup_fake_relay_log.inc'.

Unlike other platforms --mfpmath=sse is the default 
gcc mode on Mac OS X Intel. So it is unnecessary
to switch FPU to double precision mode (in fact,
it even breaks some math library functions).

Conflicts:
  - storage/myisam/mi_static.c

as the bug#46931 and bug#43913 have been closed.
