[NET]: Remove in-code externs for some functions from net/core/dev.c Inconsistent prototype and real type for functions may have worse consequences, than those for variables, so move them into a header.

netns: Fix device renaming for sysfs When a netdev is moved across namespaces with the 'dev_change_net_namespace' function, the 'device_rename' function is used to fixup kobject and refresh the sysfs tree. The device_rename function will call kobject_rename and this one will check if there is an object with the same name and this is the case because we are renaming the object with the same name. The use of 'device_rename' seems for me wrong because we usually don't rename it but just move it across namespaces. As we just want to do a mini "netdev_[un]register", IMO the functions 'netdev_[un]register_kobject' should be used instead, like an usual network device [un]registering. This patch replace device_rename by netdev_unregister_kobject, followed by netdev_register_kobject. The netdev_register_kobject will call device_initialize and will raise a warning indicating the device was already initialized. In order to fix that, I split the device initialization into a separate function and use it together with 'netdev_register_kobject' into register_netdevice. So we can safely call 'netdev_register_kobject' in 'dev_change_net_namespace'. This fix will allow to properly use the sysfs per namespace which is coming from -mm tree.
