Subject: CMake: Add basic CMake build system

Introduce an initial CMake buildsystem. This build system can build
a fully working apt system without translation or documentation.

The FindBerkelyDB module is from kdelibs, with some small adjustements
to also look in db5 directories.

Initial work on this CMake build system started in 2009, and was
resumed in August 2016.
