all: port everything to libnm

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.
