* load_driver() now uses republish_driver() instead of publishing all
devices every time. This allows published nodes to remain stable, no
matter if the driver has been unloaded in the mean time or not.
* Offloaded driver reloading to a kernel daemon. Since this is regarded
to happen rarely, a simple event variable will be set when something
happened, and the daemon will then check all known drivers.
* devfs_open() will now check if the driver has to be reloaded, and will
do so before opening the device.
* Moved republish_driver() around again.
