1. Constant values of binlog positions replaced by seeking them in binlog/relay log.
2. Updated result file

In case of ROW item each compared pair does not
check if argumet collations can be aggregated and
thus appropiriate item conversion does not happen.
The fix is to add the check and convertion for ROW
pairs.


mysql-test/r/row.result:
  test result
mysql-test/t/row.test:
  test case
sql/item.cc:
  added agg_item_set_converter() function which was a part of
  agg_item_charsets() func. The only difference is that
  agg_item_set_converter() checks and converts items 
  using already known collation.
sql/item.h:
  added agg_item_set_converter() function
sql/item_cmpfunc.cc:
  In case of ROW item each compared pair does not
  check if argumet collations can be aggregated and
  thus appropiriate item conversion does not happen.

Replacing AC_CHECK_FUNC+AC_CHECK_LIB combination with
AC_SEARCH_LIBS.

returns short string value. 
 
Multibyte character sets were not taken into account when 
calculating max_length in Item_param::convert_str_value(). As a 
result, string parameters of a prepared statement could be 
truncated later when calculating string length in characters by 
dividing length in bytes by the charset's mbmaxlen value (e.g. in 
Field_varstring::store()). 
 
Fixed by taking charset's mbmaxlen into account when calculating 
max_length in Item_param::convert_str_value().


sql/item.cc:
  Multiply string's length in characters by charset's mbmaxlen when 
  calculating max_length.
tests/mysql_client_test.c:
  Added a test case for bug #41078.

      
Removed the misleading "NOTE:" from the \h command. 

client/mysql.cc:
  Bug #26724: removed the misleading note from the \h command

Substitute all references of MySQL version "5.2" to "6.0" in
deprecation warning messages.Deprecated constructs are being
removed in the 6.0 tree.

mysql-test/t/gis.test:
  IA64 gcc backend lacks -fno-fused-madd option, so we have to adjust results.

mysql-test/r/type_float.result:
  Added missing DROP TABLE.

mysql-test/r/parser.result:
  Take additional precision into account.

mysql-test/suite/funcs_1/r/memory_func_view.result:
  Take additional precision into account.
mysql-test/suite/funcs_1/r/memory_views.result:

  Take additional precision into account.

  Take additional precision into account.

  Added missing DROP TABLE.

stack reservation too small

Problem: some tests fail on HP-UX due to insufficient stack reservation.

Fix: increase stack reservation.


sql/mysql_priv.h:
  Fix for bug#21476: stack overflow crashes server; error-message
  stack reservation too small
    - raised STACK_MIN_SIZE to pass execution_constants.test on HP-UX.

Cleaned up SQL code in the test.
Needed to move the FLUSH TABLES statement prior to the DROP TABLE t1 to prevent a warning of
Table open on delete and a test fail.
