8b572ade81 Found edge cases with custom qtables
And there was a lingering bug since the previous qtable unsigned char fix
(#1814) since the call to array.array was in another place, the roundtrip was no
longer equivalent.

That was a minor change, but the revised test wouldn't pass because saving an image
with one custom qtable automatically adds a second to it by the call to
jpeg_set_defaults.
With 1 or >2 custom tables, there is extra work we have to do due to that call.

416d8e340e Fixed issue #857.
When saving a JPEG and specifying 'keep' for quality or subsampling,
if the source JPEG image is in grayscale mode, don't try to find the
subsampling of the source, because grayscale images don't have any
subsampling (it's only for color components).

For the moment the fix also ignores subsampling of CMYK JPEG because
currently Pillow doesn't support encoding JPEG in YCCK mode (and
subsampling doesn't make sense in CMYK, but Pillow permits saving CMYK
JPEG with subsampling, that's a bug). This fix pass those errors
silently, i.e. it doesn't raise an error when 'keep' is used but it's
not possible to keep the subsampling (because the image is grayscale
or CMYK). I think it's the proper behavior but I'm not sure.

14976346a8 Fixed import for Python 3.
Fixed the trivial import bug that prevented the Python 3 version of MPO
from running. On the way fixed the trivial C bug that prevented
Convert.c from compiling properly in a Mac OS X environment for a
Python 3 target.
