Use this instead of malloc().

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.

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.

POLY: cleanup pb_starmultiply() 
* avoid side effects
* use MP_DIV instead of MP_MOD
* move mp_modulus initialization to outer scope

POLY: improve error handling 
Use MP_ADD, MP_MUL, PB_ADD, PB_MUL etc instead of the mp_add,...
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.
