strstrip(): mark as as must_check
strstrip() can return a modified value of its input argument, when removing elading whitesapce. So it is surely bug for this function's return value to be ignored. The caller is probably going to use the incorrect original pointer. So mark it __must_check to prevent this frm happening (as it has before).
