Make RF_INCLUDE_RAID6 build (needs more changes to make it work).

Fix function signatures - recovFunc has a return type of void.
Fix obvious errors/typos from previous "mechanical changes".
MapSector no longer takes a row value.
Cleanup (now unused) row usage.
rf_bxor() doesn't take a bp argument.

Merge thorpej-cfargs2.

s/overwriten/overwritten/ in comments.

branches: 1.14.2;
fix typos in word "otherwise".

branches: 1.13.72;
According to the Oxford Dictionary of Etymology, a wether is a male sheep
or ram.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

branches: 1.11.74; 1.11.84; 1.11.90;
merge ktrace-lwp.

nuke trailing whitespace

branches: 1.9.8; 1.9.10;
iCleanup the RF_CREATE_PARAM3(). Middle two "arguments" were nothing
but 0 in all cases.

branches: 1.8.16;
add RCSIDs

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for
the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h,
rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places.
Believe it or not, when this is all done, things will be cleaner.

No functional changes to RAIDframe.

branches: 1.6.2;
bzero -> memset

branches: 1.5.14; 1.5.16;
Make these compile with RF_INCLUDE_RAID6.

rf_sys.h does not need to be #included in any of these files, and, actually,
is no longer needed at all.

Phase 2 of the RAIDframe cleanup. The source is now closer to KNF
and is much easier to read. No functionality changes.

RAIDframe cleanup, phase 1. Nuke simulator support, user-land driver,
out-dated comments, and other unneeded stuff. This helps prepare
for cleaning up the rest of the code, and adding new functionality.

No functional changes to the kernel code in this commit.

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.
