d498ddf1a8 ASCII->POLY: written a function to convert a char* string into a polynom. 
The function returns a newly allocated poynom of the string size * 7
7 bits per ASCII symbol.
the function need to be warped so the maximal poynom is corresponding to
the NTRU context.

POLY: allow signed int in MP_SET_INT 
Now you can pass MP_SET_INT(&foo, -1) without having
to call mp_neg() later etc.

0bdddc12e7 rand: Refactoring finished 
now there are only 4 static functions left:
static mp_digit read_int_dev_random();
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);
But this need to be checkt by a other group member

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.
