Adjust the test result and mention that the introduced restriction
has been reported as MySQL Bug #51451.

innobase_check_index_keys(): Add a parameter for the InnoDB table and
check that no duplicate index name is added.  Report errors by
my_error() instead of sql_print_error().

branches/zip: Allocate the merge sort buffers from a heap, not stack.

The merge sort can use up to 48KiB of buffers when merging blocks.
That can cause a stack overflow, especially on 64-bit systems when not
building with inlined functions.  This was reported as Issue #462.

row_merge_dup_report(): Allocate buf and offsets from a heap.

row_merge_heap_create(): Allocate space for buf[3] too. Fix bogus
sizeof arithmetics that happened to work, because
sizeof(ulint)==sizeof(void*).

row_merge_blocks(), row_merge_blocks_copy(): Allocate buf[3] from heap.

row_merge_insert_index_tuples(): Allocate buf from graph_heap.

branches/zip bug# 49535

This is a backport of r4924.
mem_heap_get_size() scans all allocated blocks to calculate the total
size of the heap. This patch introduces a new, total_size, field in
mem_block_info_struct. This field is valid only for base block 
(i.e.: the first block allocated for the heap) and is set to
ULINT_UNDEFINED in other blocks.
This considerably improves the performance of redo scan during recovery.

branches/zip: Relax a debug assertion about a missing BLOB. (Issue #452)
When rolling back an incomplete transaction in purge, tolerate missing
BLOBs also in update undo, when undoing an INSERT by updating a delete-marked
record, and the delete-marked record is no longer needed.
Previously, we only tolerated missing BLOBs in insert undo.
This merely fixes a debug assertion; the code performed correctly
without UNIV_DEBUG.
