Jonathan Li ab9bdb009b baseclasses: Move from unfree to 3rdparty
Update it to the version found at
https://github.com/Microsoft/Windows-classic-samples , which is in an
MIT licensed repo, and add the LICENSE file (edited to remove the SIL
Open Font LICENSE part since that doesn't apply).

Some modifications have been made to reduce the diff/stop git
complaining (not including any file that wasn't in the previous version
and removing the related header includes in streams.h, and fixing some
but not all of the whitespace issues).
