Redo domain registration to use SYSINITS rather than linker sets.
Get rid of the spl wrapper kludge, it doesn't seem to be needed between init calls since all that's running is the domain/protocol timers and they are safe since domain list modifications are splnet() protected (which blocks the timers)
