Since the API has not changed at this point, this is mostly just a matter of updating Makefiles, and changing references to the library name in comments. NetworkManager cannot link to libnm due to the duplicated type/symbol names. So it links to libnm-core.la directly, which means that NetworkManager gets a separate copy of that code from libnm.so. Everything else links to libnm.
