76b8386550 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.

5e2c06a1c7 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.


sql/handler.h:
  cursor's creation functions in the handlerton need a THD,
  it's better than have the engine call current_thd
sql/sql_cursor.cc:
  pass the THD instead of letting the engine call current_thd
storage/innobase/handler/ha_innodb.cc:
  use the passed THD instead of current_thd

bf2f50d345 Applied innodb-5.1 snapshots ss799 and ss854 
Bugs fixed:
- Bug #20877: InnoDB data dictionary memory footprint is too big
- Bug #13544: Second delete of same row in transaction illustrates non-optimal locking
- Bug #20791: valgrind errors in InnoDB


storage/innobase/btr/btr0btr.c:
  Applied innodb-5.1 snapshots ss799 and ss854
  
  Revision r823:
  Minor cleanup related to Bug #20877.
  
  btr_print_recursive(): Replace tree->tree_indexes with tree->index.
  This should have been done in r453.
  
  univ.i: Add UNIV_BTR_PRINT.
  
  rw_lock_t: Reduce writer_is_wait_ex to a bit and move it close to
  other bitfields.  Change the types to unsigned, in case ulint or ibool
  bitfields will not work.
  
  
  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)
  
  struct dict_tree_struct, dict_tree_t: Remove.
  
  struct dict_index_struct: Add page and lock.
  
  dict_tree_create(): Remove.  Replace the invocation with
  assignment to index->page and a call to rw_lock_create(&index->lock).
  
  dict_tree_free(): Remove.  Replace the invocation wtih
  a call to rw_lock_free(&index->lock).
  
  dict_index_get_tree(): Remove.
  
  dict_tree_get_space_reserve(): Rename to dict_index_get_space_reserve()
  and remove the parameter, which was unused.
  
  btr_level_list_remove(): Remove the unused parameter "tree".
  
  Replace the occurrences of "tree" with "index" in names of variables,
  functions and data types, e.g. "dict_tree_t tree" becomes
  "dict_index_t index".  Remove local variables "tree" or "index" of
  functions that needed both "tree" and "index".
  
  
  Revision r834:
  dict_col_t: Copy the fields of "dtype_t type" directly to this structure,
  so that all integer fields can be packed into 64 bits.  (Bug #20877)
  
  dtype_t: Change the type of all bit-fields to unsigned.
  
  dict_table_get_nth_col(), dict_table_get_sys_col_noninline(),
  dict_table_get_sys_col(), dict_field_get_col(): Return const
  dict_col_t*, so that changes to dict_col_t can be detected more
  easily.  Add const to many dict_col_t* declarations.
  
  dict_index_get_nth_type(): Replace with dict_index_get_nth_col().
  
  dict_col_get_type(): Replace with dict_col_copy_type().
  
  dict_col_get_min_size(), dict_col_get_max_size(), dict_col_get_fixed_size(),
  dict_col_get_sql_null_size(): New functions.
  
  dtype_get_at_most_n_mbchars(): Replace the parameter dtype
  with the parameters prtype, mbminlen, mbmaxlen.
  
  dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(),
  cmp_whole_field(): Replace the dtype_t* parameter with the ulint
  parameters mtype, prtype.
  
  dtype_copy(): Add a const qualifier to type2 (the one being copied from).
  
  dtype_set_mblen(): Replaced with dtype_get_mblen().
  
  dtype_get_fixed_size_low(), dtype_get_min_size_low(),
  dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(),
  dtype_get_min_size(), and dtype_get_max_size().  These are used by the
  dict_col_get_{fixed,min,max}_size() functions.
  
  cmp_types_are_equal(): Replace with cmp_cols_are_equal().
  
  dict_table_get_col_name(): Add a const qualifier parameter to the
  parameter "table".
  
  dtype_binary, dtype_binary_val: Remove.
  
  dtype_is_fixed_size(): Remove.
  
  
  Revision r837:
  page_offset(): New function to replace many ut_align_offset(., UNIV_PAGE_SIZE)
  calls.
  
  dict_index_build_node_ptr(): Correct a typo in a comment.
  
  
  Revision r838:
  Revamp the line splits done in r763 and r764 that can now be done better,
  thanks to r826.

  the precision of decimal columns in stand-alone InnoDB.
  
  dtype_get_prec(): Remove.

  dict_col_t: Turn ind, clust_pos, and ord_part into bit-fields.
  
  Replace the default clust_pos value ULINT_UNDEFINED with
  REC_MAX_N_FIELDS and replace all references to clust_pos with calls to
  the accessor function dict_col_get_clust_pos().
  
  dict_field_t: Turn prefix_len and fixed_len into bit-fields.
  
  dict_tree_t: Remove pad[64].
  
  dict_table_t: Turn the fields ibd_file_missing, tablespace_discarded,
  cached, flags, stat_initialized, and autoinc_inited into bit-fields.
  Remove does_not_fit_in_memory from non-debug builds.

  We could shrink the structure further to three 32-bit words or two
  64-bit words by turning the remaining fields to bit-fields.
  Unfortunately, the fields are not protected by any mutex, and thus we
  would better keep each field aligned to a machine word.

  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)

  functions that needed both "tree" and "index".
  
  
  Revision r832:
  Add dict_table_get_col_name() in preparation for getting rid of
  dict_col_t::name, and use it instead of col->name everywhere.
  
  Revision r833:
  Tweak the bit-field definitions introduced since r813 to address Bug #20877.
  
  rw_lock_t: Do not make writer_is_wait_ex a bit-field.  There are no fields
  yet that could be fused to the same machine word, but we play it safe,
  because the field writer_is_wait_ex may be modified by several threads
  simultaneously.  Such fields should always be allocated an own machine
  word.
  
  dict_table_t: Change the type of all bit-fields to "unsigned".  Make
  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.
  
  dict_build_table_def_step(): Pass a local variable to
  fil_create_new_single_table_tablespace() and initialize table->space
  from it after the call, now that table->space is a bit-field.

  dtype_get_fixed_size_low(), dtype_get_min_size_low(),
  dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(),

  dict_col_get_{fixed,min,max}_size() functions.
  
  cmp_types_are_equal(): Replace with cmp_cols_are_equal().
  
  dict_table_get_col_name(): Add a const qualifier parameter to the

  Revision r818:
  Remove dict_col_t::hash, dict_col_t::table,
  dict_sys->col_hash, and DICT_POOL_PER_COL_HASH.  (Bug #20877)
  
  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),
  dict_col_remove_from_cache(): Remove.  These only updated dict_sys->col_hash.
  
  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.
  
  
  Revision r819:

  row_upd_index_replace_new_col_vals(): Compute clust_index outside
  the loops.  Compute clust_pos outside the inner loop.

  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256

  Revision r816:
  Remove more remnants of mixed indexes.
  
  Revision r818:
  Remove dict_col_t::hash, dict_col_t::table,
  dict_sys->col_hash, and DICT_POOL_PER_COL_HASH.  (Bug #20877)
  
  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),
  dict_col_remove_from_cache(): Remove.  These only updated dict_sys->col_hash.
  
  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.
  
  
  Revision r820:
  Remove dict_col_t::clust_pos.
  
  dict_col_get_clust_pos(): Add parameter clust_index.  Replace the
  look-up with a linear search of all columns in the clustered index.
  
  row_upd_index_replace_new_col_vals(): Compute clust_index outside
  the loops.  Compute clust_pos outside the inner loop.
  
  row_upd_changes_ord_field_binary(), row_upd_changes_first_fields_binary():
  Compute clust_index outside the loops.  Declare the auxiliary variables
  inside the loop scope.
  
  
  Revision r827:
  Make dict_index_find_cols() always succeed.
  
  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)

  btr_level_list_remove(): Remove the unused parameter "tree".
  
  Replace the occurrences of "tree" with "index" in names of variables,
  functions and data types, e.g. "dict_tree_t tree" becomes
  "dict_index_t index".  Remove local variables "tree" or "index" of
  functions that needed both "tree" and "index".

  dtype_get_fixed_size_low(), dtype_get_min_size_low(),
  dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(),
  dtype_get_min_size(), and dtype_get_max_size().  These are used by the
  dict_col_get_{fixed,min,max}_size() functions.

  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.

  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
