Subject: ext: dsent: adds a Python interface, drops C++ one This patch
 extensively modifies DSENT so that it can be accessed using Python. To access
 the Python interface, DSENT needs to compiled as a shared library. For this
 purpose a CMakeLists.txt file has been added.  Some of the code that is not
 required is being removed.
