[PATCH] Give a hint when 'udevd' is ready to operate

Hello,

please apply the attached patch. It creates the '/dev/.udev' directory
when 'udevd' is ready to operate.

This helps init methods like 'initng' or 'minit' to stop future
processing (e.g. invoking 'udevtrigger') until 'udevd' is fully
initialized. Currently, there does not seem to exist a way to wait
for 'udevd' (resp. to check whether it is ready) and issued uevent's
may disappear silently.

With this patch, the init methods can test for /dev/.udev (e.g. waiting
actively or using inotify) after 'udevd' has been started.
