Pauli Virtanen 3cade43cf3 test-resample: add test for floating point rounding producing bad in_len 
If phase is float, calculations in impl_native_in_len/out_len don't
necessarily match with do_resample, because e.g.

    float phase0 = 7999.99;
    float phase = phase0;
    int frac = 8000, out_rate = 8000, n = 64, count = 0;
    for (int j = 0; j < n; ++j) {
        phase += frac;
        if (phase >= out_rate) {
                phase -= out_rate;
                count++;
        }
    }
    printf("count = %d\n", count);      /* count = 64 */

    count = (int)(phase0 + n*frac) / out_rate;
    printf("count = %d\n", count);      /* count = 65 */

don't give the same result.

Also add test where floating point multiplication rounding up to nearest
in

    float ph = phase * pm;
    uint32_t offset = (uint32_t)floorf(ph);

computation results to offset+1 > data->n_phases, accessing filter array
beyond bounds.  (The accessed value is still inside allocated memory
block, but contains unrelated values; the test passes silently.)
