libnm: add libnm/libnm-core (part 1)

This commit begins creating the new "libnm", which will replace
libnm-util and libnm-glib.

The main reason for the libnm-util/libnm-glib split is that the daemon
needs to link to libnm-util (to get NMSettings, NMConnection, etc),
but can't link to libnm-glib (because it uses many of the same type
names as the NetworkManager daemon. eg, NMDevice). So the daemon links
to only libnm-util, but basically all clients link to both.

With libnm, there will be only a single client-visible library, and
NetworkManager will internally link against a private "libnm-core"
containing the parts that used to be in libnm-util.

(The "libnm-core" parts still need to be in their own directory so
that the daemon can see those header files without also seeing the
ones in libnm/ that conflict with its own headers.)

[This commit just copies the source code from libnm-util/ to
libnm-core/, and libnm-glib/ to libnm/:

  mkdir -p libnm-core/tests/
  mkdir -p libnm/tests/
  cp libnm-util/*.[ch] libnm-util/nm-version.h.in libnm-core/
  rm -f libnm-core/nm-version.h libnm-core/nm-setting-template.[ch] libnm-core/nm-utils-enum-types.[ch]
  cp libnm-util/tests/*.[ch] libnm-core/tests/
  cp libnm-glib/*.[ch] libnm/
  rm -f libnm/libnm_glib.[ch] libnm/libnm-glib-test.c libnm/nm-glib-enum-types.[ch]
  cp libnm-glib/tests/*.[ch] libnm/tests/
