structure passed from MySQL. For now, we resort to the traditional
way of scanning index->table for the index number.

accessing uninitialized memory in Valgrind-instrumented builds.

(this changeset does not introduce any changes)

This is a port of
vasil.dimov@oracle.com-20100521175337-c1b1lqxgizqegb0w and
vasil.dimov@oracle.com-20100521180951-mef23h24k023xuwq
from mysql-trunk-innodb

Store the max_space_id in the data dictionary header in order to avoid
space_id reuse.

DICT_HDR_MIX_ID: Renamed to DICT_HDR_MAX_SPACE_ID, DICT_HDR_MIX_ID_LOW.

dict_hdr_get_new_id(): Return table_id, index_id, space_id or a subset of them.

fil_system_t: Add ibool space_id_reuse_warned.

fil_create_new_single_table_tablespace(): Get the space_id from the caller.

fil_space_create(): Issue a warning if the fil_system->max_assigned_id
is exceeded.

fil_assign_new_space_id(): Return TRUE/FALSE and take a pointer to the
space_id as a parameter. Make the function public.

fil_init(): Initialize all fil_system fields by mem_zalloc(). Remove
explicit initializations of certain fields to 0 or NULL.

BUILD/*: Add valgrind_configs=--with-valgrind.
BUILD/*: Remove -USAFEMALLOC from valgrind_flags.

configure.in: Add AC_ARG_WITH(valgrind) and HAVE_VALGRIND.

include/my_sys.h: Define a number of MEM_ wrappers for VALGRIND_ functions.
include/my_sys.h: Make TRASH do MEM_UNDEFINED().

include/m_string.h: Remove unused macro bzero_if_purify(A,B).

_mymalloc(): Declare MEM_UNDEFINED() on the allocated memory.

_myfree(): Declare MEM_NOACCESS() on the freed memory.

storage/innobase/include/univ.i: Enable UNIV_DEBUG_VALGRIND based on
HAVE_VALGRIND rather than HAVE_purify.

Possible things to do:
 * In my_global.h, remove the defined(HAVE_purify) condition
   from the _WIN32 uint3korr().
 * In my_global.h *int*korr(), use | instead of +
   in order to keep the Valgrind V bits accurate
 * Consider replacing HAVE_purify with HAVE_VALGRIND
 * Use VALGRIND_CREATE_BLOCK, VALGRIND_DISCARD in mem_root and similar places

This merge is non-trivial since it has to introduce the DB_INTERRUPTED
error code.

Also revert vasil.dimov@oracle.com-20100408165555-9rpjh24o0sa9ad5y
which adjusted the binlog.binlog_killed test to the new (wrong) behavior

Use | instead of +, and mask out the dont-care bits in debug assertions.

This fixes the bugs in the InnoDB Plugin.

innobase_get_stmt(): New function, to retrieve the currently running
SQL statement.

    Bugfix for 53290, fast unique index creation fails on duplicate null values

    Summary:
    Bug in the fast index creation code incorrectly considers null
    values to be duplicates during block merging.  Innodb policy is that
    multiple null values are allowed in a unique index.  Null duplicates
    were correctly ignored while sorting individual blocks and with slow
    index creation.

    Test Plan:
    mtr, including new test, load dbs using deferred index creation
