POLY: fix pb_inverse_poly_q()
...
Should be correct now. Had to add get_degree(), because
pb_clamp() in conjunction with pb_cmp() does not give
expected results, see https://github.com/libtom/libtompoly/issues/3
...so don't use it.

Otherwise we might hit problems when using this as an
out-polynom in a arithmetic functions. The caller can clamp
it himself, if he needs so.

RAND: use unsigned long instead of mp_digit
...
if we use mp_set_int() instead of mp_set(), then we can use
full unsigned long integers instead of single digits. This
seems a lot safer, especially for future versions of the
random algorithm.

pb_init() which is called by init_polynom_size() will call
mp_init_copy() on chara which means that chara being a pointer
itself is useless. We can clear it directly after it has been
copied.
