mem_init(): Invoke ut_mem_init() before mem_pool_create(), because
the latter one will invoke ut_malloc().
srv_general_init(): Do not initialize the memory subsystem (mem_init()).
innobase_init(): Initialize the memory subsystem (mem_init()) before
calling srv_parse_data_file_paths_and_sizes(), which needs ut_malloc().
Call ut_free_all_mem() in error handling to clean up after the mem_init().
ut_list_mutex would be used uninitialized when innodb_use_sys_malloc=1.
This fix addresses Issue #181.
ut_mem_block_list_init(): Rename to ut_mem_init() and make public.
ut_malloc_low(), ut_free_all_mem(): Add ut_a(ut_mem_block_list_inited).
mem_init(): Call ut_mem_init().
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.

sync_array_object_signalled(): Add a (void) cast to eliminate a gcc warning

rw_lock_x_lock_low(), rw_lock_x_lock_func_nowait(): Split lines correctly.
rw_lock_set_writer_id_and_recursion_flag(): Silence a Valgrind warning.

To the files touched by the Google patch from c4144 (excluding
include/os0sync.ic because later we removed Google code from that file):
* Remove the Google license
* Remove old Innobase copyright lines
* Add a reference to the Google license and to the GPLv2 license at the top,
as recommended by the lawyers at Oracle Legal.
(followup to r4145) Non-functional change:
Change the os_atomic_increment() and os_compare_and_swap() functions
to macros to avoid artificial limitations on the types of those
functions' arguments. As a consequence typecasts from the source
code can be removed.
Also remove Google's copyright from os0sync.ic because that file no longer
contains code from Google.

This patch changes the innodb mutexes and rw_locks implementation.
On supported platforms it uses GCC builtin atomics. These changes
are based on the patch sent by Mark Callaghan of Google under BSD
license. More technical discussion can be found at rb://30

btr_search_disabled: Rename to btr_search_enabled and change the type
to char, so that it can be directly linked to the MySQL parameters.
Note that the variable is protected by btr_search_latch and
btr_search_enabled_mutex, a new mutex introduced in this patch.
btr_search_enabled_mutex: A new mutex, to protect btr_search_enabled
together with btr_search_latch.
buf_pool_drop_hash_index(): New function, to be called from
btr_search_disable().
btr_search_disable(), btr_search_enable(): Fix bugs. These functions
were previously unused.
btr_search_guess_on_hash(), btr_search_build_page_hash_index():
Check btr_search_enabled once more, while holding btr_search_latch.
btr_cur_search_to_nth_level(): Note that the reads of btr_search_enabled
may be dirty and explain why it should not be a problem.
innobase_adaptive_hash_index: Remove. The variable btr_search_enabled will be used directly instead.
innodb_adaptive_hash_index_update(): New function, an update callback for
innodb_adaptive_hash_index. This will call either btr_search_disable()
or btr_search_enable() when the value is assigned. The functions will
be called even if the value does not appear to be changed, e.g., when
setting from TRUE to TRUE or FALSE to FALSE.

a gcc warning about an assertion that trivially holds.
The warning was introduced in r4061, in the merge of
branches/innodb+ -r4053.
ibuf_insert(): Let an assertion fail if ibuf_use is unknown.
Implement the global variable innodb_change_buffering, with the
following values:
none - buffer nothing
inserts - buffer inserts (the default)

ut_sprintf_timestamp_without_extra_chars(), ut_get_year_month_day(),

assertion failure that was accidentally introduced in r4036.
Instead of calling buf_block_get_frame(), which asserts that the
block must be buffer-fixed, access block->frame directly. That
is safe, because changes of block->page.state are protected by
the buffer pool mutex, which we are holding.
This bug was reported by Michael.
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().
This will help trim the dependencies of InnoDB Hot Backup.
recv_recovery_from_checkpoint_start(): Rename to
recv_recovery_from_checkpoint_start_func(), and remove the two first
parameters unless UNIV_LOG_ARCHIVE is defined. Define and use
the auxiliary macros TYPE_CHECKPOINT and LIMIT_LSN in the function.
struct recv_sys_struct: Remove archive_group unless UNIV_LOG_ARCHIVE
is defined.
Do not define LOG_ARCHIVE unless UNIV_LOG_ARCHIVE is defined.

rec_set_nth_field(): When the field already is SQL null,
do nothing when it is being changed to SQL null. (Bug #41571)
Normally, MySQL does not pass "do-nothing" updates to the storage engine.
When it does and a column of an InnoDB table that is in ROW_FORMAT=COMPACT
is being updated from NULL to NULL, the InnoDB buffer pool will be corrupted
without this fix.

InnoDB previously treated savepoints as a stack e.g.,

This fix changes the behavior to:
SAVEPOINT a;
SAVEPOINT b;
