4f7d784a71 py3k: Actually fix the EPS encoder
The EPS encoder wasn't part of Gohlke's test suite, so the previous "fixes"
there were only expected syntactic ones. This gives a cleaner fix to the
encoder.

The decoder doesn't work in round-trip due to a missing eps_decoder method
on the core module, but it's clear it worked at some point.

8035b1a76a py3k: FIX: TGA missing o8 declaration
Plus, TGA was eligible for a round-trip test in test_imagefile. It has one
now.

a7e3b2e47b py3k: The big push
There are two main issues fixed with this commit:

* bytes vs. str: All file, image, and palette data are now handled as
  bytes. A new _binary module consolidates the hacks needed to do this
  across Python versions. tostring/fromstring methods have been renamed to
  tobytes/frombytes, but the Python 2.6/2.7 versions alias them to the old
  names for compatibility. Users should move to tobytes/frombytes.

  One other potentially-breaking change is that text data in image files
  (such as tags, comments) are now explicitly handled with a specific
  character encoding in mind. This works well with the Unicode str in
  Python 3, but may trip up old code expecting a straight byte-for-byte
  translation to a Python string. This also required a change to Gohlke's
  tags tests (in Tests/test_file_png.py) to expect Unicode strings from
  the code.

* True div vs. floor div: Many division operations used the "/" operator
  to do floor division, which is now the "//" operator in Python 3. These
  were fixed.

As of this commit, on the first pass, I have one failing test (improper
handling of a slice object in a C module, test_imagepath.py) in Python 3,
and three that that I haven't tried running yet (test_imagegl,
test_imagegrab, and test_imageqt). I also haven't tested anything on
Windows. All but the three skipped tests run flawlessly against Pythons
2.6 and 2.7.

718dbcc8ca py3k: Provide the missing pngtest_bad.png.base64
This is from http://scary.beasts.org/security/CESA-2004-001.txt. This was
missing from Gohlke's tests. With this file, I see 79 tests and no failures
on my setup from 2.6/2.7.

197885164b py3k: Backport Gohlke's tests to run on 2.6/2.7
Most of the differences are in tobytes/tostring naming and expected
behavior of the bytes() constructor. The latter was usually easy to fix
with the right bytes literal.

This is a good preview of what will have to happen in the Python 3 code.

ad784eb808 py3k: Import Christoph Gohlke's test suite
This is Christoph Gohlke's test suite from his personal PIL package found
at http://www.lfd.uci.edu/~gohlke/pythonlibs/.

This is just to bring it in as a separate commit. Future commits will align
it with Pillow.
