[issue27572] Support bytes-like objects when base is given to int()

[Martin Panter]

Martin Panter added the comment:

I am torn on this. On one hand, it would be good to be consistent with the 
single-argument behaviour. But on the other hand, APIs normally accept 
arbitrary bytes-like objects (like memoryview) to minimise unnecessary copying, 
whereas this case has to make a copy to append a null terminator.

Perhaps another option is to deprecate int(byteslike) support instead, in 
favour of explicitly making a copy using bytes(byteslike). Similarly for float, 
compile, eval, exec, which also do copying thanks to Issue 24802. But 
PyNumber_Long() has called PyObject_AsCharBuffer() (predecessor of Python 3’s 
bytes-like objects) since 1.5.2 (revision 74b7213fb609). So this option would 
probably need wider discussion.

Thanks for the reviews Martin. Change the doc and test.

All tests passed now. :) I think it's OK. Also upload the v10 version restore 
the statement to avoid the crash you mentioned in comments.
