This is a partial revert of a4e2f2e687.
That fix tried to avoid the risk of a crash in pixel() by ensuring
Mono QImages created with external data also got a default color
table. However, that broke usable behavior in existing code that was
painting in Mono QImages using color0/color1.
This commit reverts to the old behavior, and instead expands on the
checking in pixel() so that lacking color table is handled gracefully
for all indexed formats.

Avoid all inplace modification of images using external data

In commit c6c9304, the earlier size limit of 128 was raised to the
format's defined maximum of 256. But the required special storage of
this size in the image structures was not implemented. Hence,
attempting to store such big icons would result in invalid image
files.
Fix the size storing details, and add some autotests of ico format

QImage::pixel() assumed that the color table was valid
for the values in the bitmap. This was always wrong
for indexed images with explicit no color table set and
was wrong for mono images that were constructed from
preexisting data.
For mono images, we default to a black/white color table,
like we do when constructing with uninitialized data.
For indexed image, we always default to no color table,
but instead of crashing in pixel(), we warn and return
an undefined value.

"In earlier versions of Visual C++, the compiler used several discrete
heaps, and each had a finite limit. Currently, the compiler dynamically
grows the heaps as necessary up to a total heap size limit, and requires a
fixed-size buffer only to construct precompiled headers. Consequently, the
/Zm compiler option is rarely necessary."
