Summary: urllib2 - Fix line breaks in authorization headers

Initial Comment:
urllib2 uses the wrong base64 encode function from the
base64 library. This patch corrects that.

Original bug report from "The Doctor What"
<docwhat+list.python-dev at gerf.org>

I found a bug in urllib2's handling of basic HTTP
authentication.

urllib2 uses the base64.encodestring() method to encode the
username:password.

The problem is that base64.encodestring() adds newlines
to wrap the
encoded characters at the 76th column.

This produces bogus request headers like this:
---------->8---------cut---------8<----------------
GET /some/url HTTP/1.1
Host: some.host
Accept-Encoding: identity
Authorization: Basic
cmVhbGx5bG9uZ3VzZXJuYW1lOmFuZXZlbmxvbmdlcnBhc3N3b3JkdGhhdGdvZXNvbmFuZG9uYW5k
b25hbmRvbmFuZG9u

User-agent: some-agent
---------->8---------cut---------8<----------------

Ah yes, you are correct that urllib has the same problem. I
have attached a patch to correct all of those instances as well.

It is note-worthy that the one usage of decodestring in
urllib is correct (as it is decoding the body of the
response and should reasonably expect to see newlines in
that encoding).

urllib should also be fixed.
