Rename files to 8.3 for DOS builds

DOS cannot handle long filenames.

The original and new file names are:

Note that the folder "csrc/win32_console" became "csrc/win32csl".

Updated all Makefiles and CMakeLists.txt to reflect the changes.

Special thanks to https://github.com/guberathome for providing scripts
to do the conversion. See #201

Fixes #216
