This addresses bug #419390 by anthonybaxter.

Instead of wrapping a string-to-be-decoded into a
StringIO class and using base64.decode use
binascii.a2b_base64 directly.

Speedup for big files is over 10 times (on Linux x86
anyway).

If uncontroversial I'll check it in.

Umm -- there's no patch here.  If there were, I bet I would 
have changed this to Accepted, though <wink>.

Mhh, I did click that "Check to Upload & Attach File" thing.

No matter what, here is the new version (including your
speedup for encodestring).

Accepted and assigned back to Peter for checkin.  Don't see 
how this could be controversial -- it's simple and 
appropriate.
