Summary: int() should guarantee truncation

Initial Comment:
The int() function currently warns that it cannot
guarantee truncation because C doesn't guarantee it. 
However, all known (to us) C implementations *do*
truncate, and the C99 standard requires it, so we might
as well change the code to promise truncation and
tighten the docs.

BTW, note that I wasn't guessing about the behavior of "all 
known Python platforms":  Python's test_b1.py has been 
checking all along that int(float) truncates, so if there 
were a platform where that didn't happen, we would have 
heard about it.
