Apply InnoDB snapshot ss923

Fixes:
- Bug #18077: InnoDB uses full explicit table locks in stored FUNCTION


storage/innobase/btr/btr0btr.c:
  Apply InnoDB snapshot ss923
  
  Revision r919:
  btr_page_get_father_for_rec(): Remove bogus comment about removed dict_tree_t.
storage/innobase/dict/dict0dict.c:
  Apply InnoDB snapshot ss923
  
  Revision r892:
  Merge changes from MySQL AB.
  
  dict_col_copy_type_noninline(): Remove the return statement.
  Some compilers do not allow return expressions of void type.
  
  innobase_start_or_create_for_mysql(): Do not cap srv_max_threads to 1000
  on Windows.
  
  Makefile.am (EXTRA_DIST): Add plug.in
  
  
  Revision r897:
  dict_index_get_if_in_cache(): Enclose in #ifdef UNIV_DEBUG.
  Replace the search loop with a call to dict_index_find_on_id_low().
storage/innobase/handler/ha_innodb.cc:
  Apply InnoDB snapshot ss923
  
  Revision r887:
  storage/innobase/handler: Merge changes from MySQL AB:

    2006/09/30 12:49:46-07:00 brian@zim.(none) 
    This patch adds handlerton passing to functions. NDB and Innodb still require a global hanlderton in the main code due to the nature of the sql_cache call back function (should be solveable... another patch).
    Partitioning now has a flag to allow disabling of engines from being compatible with partitioning. Cleaned up heap naming convention on panic call. 
  
  ChangeSet
    2006/09/29 17:19:02-07:00 brian@zim.(none) 
    This removes the passing of global hton to engine instance.

    2006/09/28 13:22:56+02:00 gbichot@dl145h.mysql.com 
    Merge gbichot@bk-internal:/home/bk/mysql-5.1-arch

  ChangeSet
    2006/09/28 13:19:43+02:00 gbichot@dl145h.mysql.com 
    In the handlerton, cursor creation function don't have an argument
    and so the engine calls current_thd to derive transaction information;
    instead we now pass THD to those functions, it looks more logical
    (it makes the implicit current_thd parameter more visible).
    Approved by Brian and Monty.

  Revision r895:
  Merge changes from MySQL AB, and remove two compilation warnings.
  
  ha_innodb.cc: innodb_mutex_show_status(): Add (ulong) casts to
  ulonglong expressions being passed to fprintf %lu.  The warnings
  were apparently introduced by MySQL AB developers.
  
  mysql_declare_plugin(innobase): Add PLUGIN_LICENSE_GPL.
  
  have_innodb.inc: Merge changes from MySQL AB.
  
  
  Revision r923:
  ha_innobase::store_lock(): When downgrading table locks, do not
  check thd->in_lock_tables but test if
  thd->lex->sql_command == SQLCOM_LOCK_TABLES
  instead.  Otherwise, stored functions will use table locks.  (Bug #18077)
  
  This patch is from Heikki.

  Revision r869:
  row_purge_parse_undo_rec(): Correct a faulty condition.  Luckily, this
  bug would only surface if the InnoDB SQL interpreter were used for
  updating fixed-length columns.  Currently (as the UPD_NODE_NO_SIZE_CHANGE
  flag is never set), cmpl_info can only be 0 or UPD_NODE_NO_ORD_CHANGE.
  Luckily, UPD_NODE_NO_ORD_CHANGE is 1, and the condition was simplified
  to !cmpl_info.
