POLY: add pb_mod2_to_modq()
This should make pb_inverse_poly_q() a bit more readable.
TODO: make the algorithm more descriptive in general.

POLY: introduce delete_polynom_multi()
Just a wrapper around delete_polynom() to handle multiple args.
Must be called with NULL as last argument!

POLY: use our MACROS for error handling
All mp_* and pb_* functions that return an error code
should only be called via a MACRO which handles the error.

hasufell 302cd5e4d8
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.

functions to make use of error handling.

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.

POLY: add build_polynom() method
We can build a polynom via an array of integers or just an empty
one, so that it is initialized and properly allocated.

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.

RAND: fix memory leak
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.
