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.

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.

dfb1b144d8 py3k: Remove Image types import
For awhile now, str == type("") and so on. So we use the appropriate int,
str, basestring, or tuple type where applicable.

83ff0b3b31 py3k: Use relative imports
In py3k, imports are absolute unless using the "from . import" syntax.

This commit also solves a recursive import between Image, ImageColor, and
ImagePalette by delay-importing ImagePalette in Image.

I'm not too keen on this commit because the syntax is ugly. I might go back
and prefer the prettier "from PIL import".

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.

af5228896a py3k: Add module initialization and unicode/bytes int/long thunks
This commit:

* Adds Python 3 module initialization functions. I split out the main init
  of each module into a static setup_module function.
* Adds a py3.h which unifies int/long in Python 3 and unicode/bytes in
  Python 2. _imagingft.c unfortunately looks a little kludgy after this
  because it was already using PyUnicode functions, and I had to mix and
  match there manually.

With this commit, the modules all build successfully under Python 3.

What this commit does NOT do is patch all of the uses of PyArg_ParseTuple
and Py_BuildValue, which all need to be checked for proper use of bytes
and unicode codes. It also does not let selftest.py run yet, because there
are probably hundreds of issues to fix in the Python code itself.

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.
