bmpblk: Port to Python 3
Port Python scripts to Python 3. Remove the outdated bitmap_viewer
utility and related files due to lack of Python 3 support.
As a side effect, the package Pillow is upgraded from 1.1.7 to 3.4.2.
The ANTIALIAS filter was previously used to resize the image in
build_images.py for producing high quality images. Starting from Pillow
2.7.0, however, all the filters are changed to be convolutions-based. As
a result, this patch changes to use the default BICUBIC filter, which
improves the image quality, mitigates text color deviation, and reduces
the bitmap archive size after LZMA compression.
