Uses k_size as an signed integer buf_incrwritepos() and mp_to_unsigned_bin() functions use k_size as signed integer argument. k_size is also used in an assertion that compared it to curve_size which is a signed long. Only buf_getwriteptr() is using k_size as unsigned. So it safe to use it as signed.
