New records_in_range() interface (similar to read_range())
Macros for faster bitmap handling
Simplify read_range() code (#WL1786)
New general key_cmp() function to compare keys




heap/hp_hash.c:
  New records_in_range() interface
include/heap.h:
  New records_in_range() interface
include/my_base.h:
  Moved 'key_range' here so that all table handlers can use it
include/my_bitmap.h:
  Make some bitmap functions inline for faster usage in one thread

  Indentation fixes
myisam/sp_test.c:
  New records_in_range() interface
  Indentation fixes
myisammrg/myrg_range.c:

sql/ha_ndbcluster.cc:
  New records_in_range() interface
sql/ha_ndbcluster.h:
  New records_in_range() interface
sql/handler.cc:
  Simplify read_range() interface:
  - Add 'eq_range' to read_range_first
  - Remove 'eq_range' parameer from read_range_next()
  - Trust values from index_next_same()
  - Simplfy compare_key() by moving key_comparision to key.cc (as this code can be reused from other places)
sql/handler.h:
  Move key_range to my_base.h to be used by external table handlers
  Simplify read_range() interface
  New records_in_range() interface
sql/key.cc:
  Rename key_cmp() to key_cmp_if_same() to make it more descriptive
  Add new key_cmp() function usable from range and handler code.
sql/mysql_priv.h:
  Prototypes for new functions
sql/opt_range.cc:
  New records_in_range() interface
  Simplify cmp_prev()
  (We can in 5.0 simplify cmp_next() the same way)
sql/opt_range.h:
  Added key_part_info to QUICK_SELECT to be able to use key_cmp() in get_next()
sql/opt_sum.cc:
  key_cmp -> key_cmp_if_same
sql/sql_acl.cc:
  key_cmp -> key_cmp_if_same
sql/sql_select.cc:
  key_cmp -> key_cmp_if_same
