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.

af94e2d93d py3k: Map long type to int
int() is really now long() in py3k, but to avoid breaking 2.6/2.7, we leave
the integer types where they are and just map long to int in py3k.

Also, pretty proud of myself for finding an easy way of detecting py3k.

31c454b925 py3k: 2to3's "idiom" filter
This is, I guess, a few things the Python devs were just fed up with.

* "while 1" is now "while True"
* Types are compared with isinstance instead of ==
* Sort a list in one go with sorted()

My own twist is to also replace type('') with str, type(()) with tuple,
type([]) with list, type(1) with int, and type(5000.0) with float.

260c1fad14 py3k: Convert StringIO.StringIO to io.BytesIO
io.BytesIO is already in 2.6. Some of the more obvious bytes literals are
marked in this commit.

Seriously, if you didn't know that, you've been in a freaking cave, man.

strings.

fc035814bd py3k: map and filter to list comprehensions
What's really going on is that map() and filter() return iterators in py3k.
I've just gone ahead and turned them all into list comprehensions, because
I find them much easier to read.

09f1081c95 py3k: Fix up uses of dictionary views, ranges, and has_key()
y.has_key(x) is gone (use x in y), and keys(), values(), items(), and
range() all return views.

Some iterables needed to be packed into lists, either because the code
expected a list (such as "range(256) * 3") or because the original
collection was being modified (automatic global declarations).

The Tiff ImageFileDictionary is a special case and will be dealt with in
another commit.

37f22ebfcd py3k: Use string methods instead of string module
First, we go for the obvious stuff. The string module methods are gone in
3.0, so we translate them to the appropriate methods on the string class.
