row_merge(): Make "half" an in/out parameter. Determine the offset of
half the output file. Copy the last blocks record-by-record instead of
block-by-block, so that the records can be counted. Check that the
input and output have matching n_rec.
row_merge_sort(): Do not assume that two blocks of size N are merged
into a block of size 2*N. The output block can be shorter than the
input if the last page of each input block is almost empty. Use an
accurate termination condition, based on the "half" computed by
row_merge().

row_merge_blocks_copy(): New function, for copying the last blocks in
row_merge(). Update and check n_rec.
This bug was discovered with a user-supplied test case that creates an
index where the initial temporary file is 249 one-megabyte blocks and
the merged files become smaller. In the test, possible merge record
sizes are 10, 18, and 26 bytes.

Unprotected updates to ut_total_allocated_memory in
os_mem_alloc_large() and os_mem_free_large(), called during
fast index creation, may corrupt the variable and cause assertion failures.
Also, add UNIV_MEM_ALLOC() and UNIV_MEM_FREE() instrumentation around
os_mem_alloc_large() and os_mem_free_large(), so that Valgrind can
detect more errors.

mem_pool_create(): Remove the assertion about size. The function will
work with any size. However, an assertion would fail in ut_malloc_low()

mem_init(): When srv_use_sys_malloc is set, pass size=1 to mem_pool_create().
mem0mem.c: Add #include "srv0srv.h" that is needed by mem0dbg.c.
If lower_case_table_names=1, MySQL will pass the table names in lower case.

within UNIV_DEBUG. The two remaining callers in non-debug builds,
btr_search_guess_on_hash() and btr_search_validate(), were rewritten
to call buf_page_hash_get().
To implement support for a resizeable buffer pool, the function
buf_block_align() had been rewritten to perform a page hash lookup in
the buffer pool. The caller was also made responsible for holding the
buffer pool mutex.
Because the page hash lookup is expensive and it has to be done while
holding the buffer pool mutex, implement buf_block_align() by pointer
arithmetics again, and make btr_search_guess_on_hash() call it. Note
that this will have to be adjusted if the interface to the resizeable
buffer pool is actually implemented.
rb://83 approved by Heikki Tuuri, to address Issue #161.
As a deviation from the approved patch, this patch also makes
btr_search_validate() (invoked by CHECK TABLE) check that
buf_pool->page_hash is consistent with buf_block_align().

buf_page_struct: Note that space and offset are also protected by
buf_pool_mutex. They are only assigned to by

hold just buf_pool_mutex when checking these fields.
buf_flush_try_page(): Rename "locked" to "is_s_latched", per Heikki's request.
buf_flush_batch(): Move the common statement mutex_exit(block_mutex)

redundant test (buf_pool->init_flush[flush_type] == FALSE) that was
apparently copied from buf_flush_write_complete().

or block_mutex. Enumerate the assumptions in debug assertions.
buf_flush_insert_sorted_into_flush_list(): Remove unused code.
Change the parameter to buf_block_t* block and assert that
block->state == BUF_BLOCK_FILE_PAGE. This is part of Issue #155.
interpreter. It was only used for updating the InnoDB internal data
dictionary when renaming or dropping tables. It could have caused
deadlocks after acquiring latches on insert buffer bitmap pages.
This and r3544 should fix Issue #135.
Furthermore, the update-in-place-in-select does not account for
compression failure. That was not a problem yet, since the InnoDB SQL
interpreter has so far assumed ROW_FORMAT=REDUNDANT.
