NetBSD/sys/dev/raidframe/rf_reconutil.h
oster 10f077a0fb [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.
