A number of after-merge fixes following merge of MySQL 5.1.44 into MariaDB.
Bug#46949: memory leak with failed alter table to create partitions based on extract() Bug#51830: Incorrect partition pruning on range partition (regression) Fixed valgrind failure in select_describe(), read of uninitialized Item_subselect::eliminated. PBXT test file updates to reflect changes done in MySQL. mysql-test/suite/pbxt/r/partition_error.result: Result file update following MySQL 5.1.44 changes. mysql-test/suite/pbxt/r/partition_pruning.result: Result file update following MySQL 5.1.44 changes. mysql-test/suite/pbxt/t/partition_error.test: Test file update following MySQL 5.1.44 changes. sql/item_subselect.cc: Fixed valgrind failure in select_describe(), read of uninitialized Item_subselect::eliminated: - it turns out we can call select_describe() without having fixed subquery items for child subselects. These are not the kind of subqueries that we could eliminate, so the fix is to ensure that item_subselect->eliminated==FALSE even before fix_fields is called. Also added code to reset item_subselect->eliminated back to FALSE in Item::reset() call. sql/item_subselect.h: Fixed valgrind failure in select_describe(), read of uninitialized Item_subselect::eliminated: - it turns out we can call select_describe() without having fixed subquery items for child subselects.

Also added code to reset item_subselect->eliminated back to FALSE in Item::reset() call. sql/sql_partition.cc: Fix Bug#51830: Revert part of the patch for Bug#49742, which caused the regression. sql/table.cc: Fix Bug#46949: memory leak in failed ALTER TABLE with partitioning.
