ebaa509d66 Adjust buffer size when icc_profile > MAXBLOCK (issue #148) 
We were encountering some errors when saving specific JPEG images.
The error was shown in stderr as:
  IOError: encoder error -2 when writing image file

And on stdout it printed:
    Suspension not allowed here

The problem was the bufsize not contemplating the icc_profile block.

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.

70a50907c2 This patch allows a JPEG image to be saved with a specific qtables 
value (in dictionary format).

Previously, this would throw a TypeError when checking if the qtables
value was actually a preset. By adding an isStringType check, we can
avoid this error.

c68044bf7f Fix IOError when saving progressive JPEGs. 
when the jpeg encoder sees the flags optimize or progressive (or progression)
it will write the full image in one shot.

The bufsize needs to be big enough to hold the entire image. The current heuristic
is that the entire compressed image will fit in width * height bytes, but this
heuristic is only applied to save operations with the flag "optimize" and not to
save operations with the flag "progressive".

This patch fixes this oversight.

(Btw, it will probably be a good idea to have a loop that retries with a bigger
bufsize in case this guess is not big enough.)

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.
