  A fix (bug #10179: error in default value setting).
  Unnecessary code removed.
sql/unireg.cc:
  A fix (bug #10179: error in default value setting).
  1. we should take into account uneven bits (for bit fields) stored among NULL bits.
  2. changed code which sets NULL bits for fields.
  3. changed code which sets unused bits after NULL bits.
  4. unused variables removed.
