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.
NetworkManager.h, NetworkManagerVPN.h, and nm-version.h are part of
the libnm-util API, so move them to libnm-util.
include/ still contains headers that are strictly NM-internal (eg,
nm-glib-compat.h).
Unfortunately, $(AM_CPPFLAGS) gets overridden by per-target _CPPFLAGS
variables, which $(INCLUDES) did not, so this requires some additional
changes.
In most places, I have just gotten rid of the per-target _CPPFLAGS
variables; in directories with a single target, the per-target
variable is unnecessary, and in directories with multiple targets, the
per-target variable is often undesirable, since it forces some files
to be compiled twice, even though there ends up being no difference
between the two files.
- the first uses dbus-glib and D-Bus "NameOwnerChanged" signal directly
- the second uses GIO's g_bus_watch_name()
- the third uses Qt and QDBusServiceWatcher class
