[dbus] The meaning of private?

[Pavel Strashkin]

Speed, memory consumption, resource management (you don't need to care
about lifetime - just call the function and be happy).
In the simple single-threaded-process application you don't need to
have multiple connections so instead of having your own global
variable for a connection and share it between all your modules (call
it whatever you want) you already have dbus_bus_get. In case if you
can't share the connection for a reason, you are provided with
dbus_bus_get_private.
