myisam/myisampack.c:
  Bug#8321 - myisampack bug in compression algorithm
  Enlarged the variables which hold Huffman codes to
  ulonglong and adjusted the functions accordingly.
  Added test code for long Huffman codes.
  Enlarged the distinct column values buffer (tree_buff)
  and added checks to stay in its range.
  Added statistics and trace prints.
  Added a lot of comments.
mysys/tree.c:
  Bug#8321 - myisampack bug in compression algorithm
  Added a check against overflow of the tree element count.
  The tree element count is only 31 bits, but sometimes
  used for big numbers. There is however no application yet,
  which relies on exact tree element counts.

  We need every instruction to have its own arena, because we want to
  track instruction's state (INITIALIZED_FOR_SP -> EXECUTED). Because of 
  `if' statements and other conditional instructions used in stored 
  procedures, not every instruction of a stored procedure gets executed 
  during the first (or even subsequent) execution of the procedure. 
  So it's better if we track the execution state of every instruction 
  independently.
  All instructions of a given procedure now also share sp_head's 
  mem_root, but keep their own free_list.
  This simplifies juggling with free Item lists in sp_head::execute.
- free_items() moved to be a member of Query_arena. 
- logic of 'backup_arena' debug member of Query_arena has been
  changed to support
  multi-backups. Until now, TRUE 'backup_arena' meant that there is
  exactly one active backup of the THD arena. Now it means simply that
  the arena is used for backup, so that we can't accidentally overwrite an 
  existing backup. This allows doing multiple backups, e.g. in
  sp_head::execute and Cursor::fetch, when THD arena is already backed up
  but we want to set yet another arena (usually the 'permanent' arena,
  to save permanent transformations/optimizations of a parsed tree).


sql/sp_head.cc:
  - use Query_arena support in sp_head::execute() as now sp_instr inherites
    from it.
sql/sp_head.h:
  - inherite sp_instr from Query_arena
sql/sql_class.cc:
  - changed the principle of Query_arena::backup_arena; free_items is now
    a member of Query_arena.
sql/sql_class.h:
  - changed the principle of Query_arena::backup_arena; free_items is now
    a member of Query_arena.
sql/sql_prepare.cc:
  free_items() is now a member of Query_arena.
sql/sql_select.cc:
  free_items() now automatically sets free_list to zero.

  The source of the problem is in Field_longlong::cmp. If 'this' is
  an unsigned number, the method casts both the current value, and
  the constant that we compare with to an unsigned number. As a
  result if the constant we compare with is a negative number, it
  wraps to some unsigned number, and the comparison is incorrect.
  
  When the optimizer chooses the "range" access method, this problem
  causes handler::read_range_next to reject the current key when the
  upper bound key is a negative number because handler::compare_key
  incorrectly considers the positive and negative keys to be equal.
  
  The current patch does not correct the source of the problem in
  Field_longlong::cmp because it is not easy to propagate sign
  information about the constant at query execution time. Instead
  the patch changes the range optimizer so that it never compares
  unsiged fields with negative constants. As an added benefit,
  queries that do such comparisons will execute faster because
  the range optimizer replaces conditions like:
  (a) (unsigned_int [< | <=] negative_constant) == FALSE
  (b) (unsigned_int [> | >=] negative_constant) == TRUE
  with the corresponding constants.
  In some cases this may even result in constant time execution.

sql/opt_range.cc:
  Added a new optimization to the range optimizer where we detect that
  an UNSIGNED field is compared with a negative constant. Depending on
  the comparison operator, we know directly that the result of the
  comparison is either TRUE or FALSE for all input values, and we need
  not check each value.
      
  This optimization is also necessary so that the index range access
  method produces correct results when comparing unsigned fields with
  negative constants.

  Fixed buf #11487.
  Added a call of  QUICK_RANGE_SELECT::init to the
  QUICK_RANGE_SELECT::reset method. Without it the second
