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.

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.

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.
