Updated init-scripts. Now support setting debug and trace options in config file. Explicitly send add-event for initial population (newer udevds will default to change). Set property STARTUP while booting for compatibility with new eg. lvm2 init-scripts. Sync udev-9999.ebuild.

(Portage version: 2.1.8.3/cvs/Linux x86_64)
