Don't include unrealized devices in checkpoint because, as the name
says, they are not real.
While at it, remove nm_manager_get_device_paths() as it is no longer
used.
Replace the usage of g_str_hash() with our own nm_str_hash().
GLib's g_str_hash() uses djb2 hashing function, just like we
do at the moment. The only difference is, that we use a diffrent
seed value.
Note, that we initialize the hash seed with random data (by calling
getrandom() or reading /dev/urandom). That is a change compared to
before.
This change of the hashing function and accessing the random pool
might be undesired for libnm/libnm-core. Hence, the change is not
done there as it possibly changes behavior for public API. Maybe
we should do that later though.
At this point, there isn't much of a change. This patch becomes
interesting, if we decide to use a different hashing algorithm.
Keep the include paths clean and separate. We use directories to group source
files together. That makes sense (I guess), but then we should use this
grouping also when including files. Thus require to #include files with their
path relative to "src/".
Also, we build various artifacts from the "src/" tree. Instead of having
individual CFLAGS for each artifact in Makefile.am, the CFLAGS should be
unified. Previously, the CFLAGS for each artifact differ and are inconsistent
in which paths they add to the search path. Fix the inconsistency by just
don't add the paths at all.
When a global checkpoint is created (one with empty device list) we
save the status of all devices to restore it later. After the
checkpoint new interfaces and connections may appear and they can
significantly influence the overall networking status, but we don't
consider them at the moment.
Introduce a new flag DELETE_NEW_CONNECTIONS to delete any connection
added after the checkpoint and similarly a DISCONNECT_NEW_DEVICES to
ensure that the connection active on newly appeared devices doesn't
disrupt network connectivity.

- use _NM_GET_PRIVATE() and _NM_GET_PRIVATE_PTR() everywhere.
- reorder statements, to have GObject related functions (init, dispose,
constructed) at the bottom of each file and in a consistent order w.r.t.
each other.
- unify whitespaces in signal and properties declarations.
- use NM_GOBJECT_PROPERTIES_DEFINE() and _notify()
- drop unused signal slots in class structures
- drop unused header files for device factories
First, consider all devices and not only realized and managed ones
when an empty list is passed. Also, move the list evaluation to the
checkpoint manager, since the check for device conflicts is done
there.
