Fix for Bug#6025 "Test "client_test" fails in 4.1.6-gamma build (2)".
 No need for a test case, the bug is covered already.

  Fix for Bug#6025 "Test "client_test" fails in 4.1.6-gamma build (2)":
  the bug was in assignments like:
    *row+= read_binary_time(tm, row);
  which makes two assingments without a sequence point (read_binary_*
  changes *row too) => undefined behaviour.
  The fix changes read_binary_{time,date,datetime} signature to get
  rid of any probability to fall into the same trouble in future.
