Summary: urllib.urlopen() raises AttributeError

Initial Comment:
When you connect urlopen() to a socket that does not send any data, it produces an AttributeError. 

File "/lib/python2.6/urllib.py", line 608, in http_error_default
    return addinfourl(fp, headers, "http:" + url)
  File "/lib/python2.6/urllib.py", line 951, in __init__
    addbase.__init__(self, fp)
  File "/lib/python2.6/urllib.py", line 898, in __init__
    self.read = self.fp.read
AttributeError: 'NoneType' object has no attribute 'read'

Raising an exception is OK (I think?), but it should be an IOError instead of an AttributeError. See the attached patch for a test case for the bug.
