libsystemd: split up into subdirs
We still only produce on .so, but let's keep the sources separate to make things a bit less messy.

+Known differences between dbus1 and kdbus:
+
+- NameAcquired/NameLost is gone entirely on kdbus backends if
+ libsystemd is used. It is still added in by systemd-bus-proxyd
+ for old dbus1 clients, and it is available if libsystemd is used
+ against the classic dbus1 daemon. If you want to write compatible
+ code with libsystem-bus you need to explicitly subscribe to
+ NameOwnerChanged signals and just ignore NameAcquired/NameLost
+
+- Applications have to deal with spurious signals they didn't expect,
+ due to the probabilistic bloom filters. They need to handle this
+ anyway, given that any client can send anything to arbitrary clients
+ anyway, even in dbus1, so not much changes.
+
+- clients of the system bus when kdbus is used must roll their own
+ security. Only legacy dbus1 clients get the old XML policy enforced,
+ which is implemented by systemd-bus-proxyd.
+
+- Serial numbers of synthesized messages are always (uint32_t) -1.
+
+- The org.freedesktop.DBus "driver" service is not special on
+ kdbus. It is a bus activated service like any other with its own
+ unique name.
+
+- NameOwnerChanged is a synthetic message, generated locally and not
+ by the driver.
+
+- There's no standard per-session bus anymore. Only a per-user bus.
