Log:
Refactored raising operations out of the external functions C code.
There are some XXX's left in raisingops.py that I would very much like
someone to have a look at. (I hope this is not too much work)
Related to there XXX's is probably the currently skipped test_int_mod_ovf_zer
test in test-typed.py
