style(9) patches to quotaon(9), repquota(9), trpt(9), lpr(9)

[Chris Pressey]

Patches to remove register keyword, de-K&R-ify, remove (void) casts when
ignoring return values - you know, the usual - can be found at:

  http://catseye.webhop.net/DragonFlyBSD/patch/style/

I'll commit the patches to quotaon, repquota, and trpt tomorrow, if
there are no objections.  I'll give lpr two days, as it's a bit more
extensive.
