Adding make_dev() and destroy_dev() calls in (hopefully) the right places. This is done by calling make_dev() in each object constructor and caching the dev_t's returned from make_dev() in each struct 'subdisk'(sd), 'plex' and 'volume' such that the 'object'_free() functioncs can call destroy dev. This change makes a subset of the old /dev/vinum appear under devfs. Enough nodes appear such that I'm able to mount my striped volume. There may be more work needed to get vinum configuration working properly.
