fixed test func_gconcat to be repeatable independent of presend tables and avoid removing user tables
mysql-test/r/func_gconcat.result:
removed warning in test
fixed table tnames (should be tN, where N is number)
mysql-test/t/func_gconcat.test:
removed warning in test
fixed table tnames (should be tN, where N is number)
sql/item_sum.cc:
added debug information
fixed memory leak in group_concat function
initialization of item_thd moved to constructor (in any case we need thd in constructor)
initialization of group_concat_max_len to constructor to avoid incorrect length reporting (BUG#757)
removed Item_func_group_concat::fix_length_and_dec() because item have its own fix_fields and will not have inherited items
mysql-test/r/func_gconcat.result:
test for BUG#757
mysql-test/t/func_gconcat.test:
test for BUG#757
sql/item_sum.cc:
reduced using of slow current_thd/current_lex macro
initialization of item_thd moved to constructor (in any case we need thd in constructor)
initialization of group_concat_max_len to constructor to avoid incorrect length reporting (BUG#757)
sql/item_sum.h:
removed Item_func_group_concat::fix_length_and_dec() because item have its own fix_fields and will not have inherited items
mysql-test/r/func_gconcat.result:
Update results
mysql-test/t/func_gconcat.test:
Make tests repeatable. The problem is that due to floating point handling / qsort implementation the way rows are read may differ between versions
