Increased heap max length to > 4G for 64 bit machines

Browse Source 
Initialize key_part->type on open. This caused key_copy() to fail for bit_fields. (key_copy is used in HANDLER and opt_range)


include/heap.h:
  Increased heap max length to > 4G for 64 bit machines
mysql-test/r/show_check.result:
  Updated results after heap size change
mysql-test/r/type_bit.result:
  Added test for bug in bit field handling (in handler and opt_range.cc)
