Drop restart_pre/restart_post

By design, restart is hard coded to run stop followed by start along
with all of the pre/post functions associated with them. Restart doesn't
need its own pre/post functions since it is possible to make any
function in an init script behave differently for a restart command by
testing against the RC_CMD environment variable.
