The device-mapper directory now holds a copy of libdm source. At the moment this code is identical to libdm. Over time code will migrate out to appropriate places (see doc/refactoring.txt). The libdm directory still exists, and contains the source for the libdevmapper shared library, which we will continue to ship (though not neccessarily update). All code using libdm should now use the version in device-mapper.
