Issue1059

Jython:

>>> x = long(None)
>>> x
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
java.lang.NullPointerException
	at org.python.core.PyLong.long_toString(PyLong.java:122)
	at org.python.core.PyLong.toString(PyLong.java:117)
	at org.python.core.PyObject.__repr__(PyObject.java:103)

CPython:

>>> long(None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: long() argument must be a string or a number, not 'NoneType'

int(None) fails as expected.

With r4699 long(None) now generates an AttributeError, which is quite a 
bit better.  Would it make sense to change long___new__ to trap this 
AttributeError and throw a TypeError, or is there a better way to do this?

i made it translate the AttributeError to TypeError in r4713

technically this will swallow any user created AttributedErrors in a 
__long__ definition, but that's just kind of how Jython does things right 
now. We do a similar translation for e.g. __complex__
