21022c9ff8 rand: extractet some double code into new functions 
this is the first step, in the next one i a going to remove
static mp_digit get_urnd_int_small(int *sign);
static mp_digit get_rnd_int_small(int *sign);
static mp_digit get_urnd_int_big(int *sign);
static mp_digit get_rnd_int_big(int *sign);

90a01a03ec rand: getting small and big polynoms is working 
pb_poly *ntru_get_urnd_poly_big(ntru_context *ctx)
pb_poly *ntru_get_rnd_poly_big(ntru_context *ctx)
are written but the testing isen working and
i think it is a bad idea to not use function poniters
at the moment we have about 4 functions that do all the same thing
and differ only in the subfunction call.
But at the moment i cat decide of we shold use
function pinter

99ebda181a 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.

0d179a0e7d POLY: don't clamp polyonmial in build_polynom() 
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.

417ce9c0f2 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.
