Add a prioritization field to the devstat_add_entry() call so that
peripheral drivers can determine where in the devstat(9) list they are inserted. This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and any ports that depend on the devstat code, since the size of the devstat structure has changed. The devstat version number has been incremented as well to reflect the change. This sorts devices in the devstat list in "more interesting" to "less interesting" order. So, for instance, da devices are now more important than floppy drives, and so will appear before floppy drives in the default output from systat, iostat, vmstat, etc. The order of devices is, for now, kept in a central table in devicestat.h. If individual drivers were able to make a meaningful decision on what priority they should be at attach time, we could consider splitting the priority information out into the various drivers. For now, though, they have no way of knowing that, so it's easier to put them in an easy to find table. Also, move the checkversion() call in vmstat(8) to a more logical place. Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and for putting up with the long time it has taken me to commit it. Bruce did object somewhat to the central priority table (he would rather the priorities be distributed in each driver), so his objection is duly noted here. Reviewed by: bde, obrien

The devstat subsystem is an interface for recording device
