New package: zxing-cpp, a C++ port of the Java ZXing library

This will be required by some KDE packages (kitinerary) to provide barcode
processing.

NOTE: there are multiple forks of this library around. This one is at least
officially sanctioned by the original ZXing developers, provides proper
library versioning (after some poking upstream) and has actual releases.
This is also the one required by the KDE package mentioned above.

See https://github.com/nu-book/zxing-cpp/issues/44 for details.
