When reading in a BMP, after processing the header, make sure that
there is enough data remaining in the source before proceeding. If not
signal that the BMP is improperly formatted.

The code is completely separated into CMYK vs RGB cases, so having two
separate private methods is better.

- All callers of CFX_DIBitmap methods use nullptr as the ICC Transform.
- The CFX_ScanlineCompositor is always initialized with a null ICC transform.
Many of its methods call TranslateScanline from the ICC module. This method
casts just uses ((CLcmsCmm*)pTransform)->m_hTransform, and this should not be
done when pTransform is nullptr.

Move CFX_DIBSource to its own file. Also move the classes that inherit from it
to their own headers. Their cpp's will be added in followup.
