    aper: Rework aper_get_length to gain lb & ub information

    This should help aper_put_length() to take proper decisions on the way
    to encode the length, since the range alone is not enough.
    A contraint of lb=1 ub=65536 would yield a range=65536, but according to
    ITU-T X.691 11.9 it shouldn't be encoded using nsnnwn since that only
    applies in case ub<65536.
    As a result, it would end up encoding/decoding it using 2 bytes while it
    should use only 1.
