un-bitrot some of this code (which is not included by default in kernels), and make it build again. XXX: Paritylogging bits still won't build.

/* $NetBSD: rf_evenodd.h,v 1.6 2006/04/26 17:08:48 oster Exp $ */
RAIDframe, version 1.1, from the Parallel Data Laboratory at Carnegie Mellon University. Full RAID implementation, including levels 0, 1, 4, 5, 6, parity logging, and a few other goodies. Ported to NetBSD by Greg Oster.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.] Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows. Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible. The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.
