now there are only 4 static functions left:

static mp_digit read_int_dev_urandom();
static mp_digit make_small_int(mp_digit random_int, int* sign);
static mp_digit make_big_int(mp_digit random_int, int* sign);
Every function is used twice.
the next goal to copy free code is to make a single function
with function pointer out of these 4:
pb_poly *ntru_get_urnd_poly_small(ntru_context *ctx);
pb_poly *ntru_get_rnd_poly_small(ntru_context *ctx);
pb_poly *ntru_get_urnd_poly_big(ntru_context *ctx);
pb_poly *ntru_get_rnd_poly_big(ntru_context *ctx);
