Extensive mechanical changes to the pools used in RAIDframe.

Alloclist remains not per-RAID, so initialize that pool
separately/differently than the rest.

The remainder of pools in RF_Pools_s are now per-RAID pools.  Mostly
mechanical changes to functions to allocate/destroy per-RAID pools.
Needed to make raidPtr available in certain cases to be able to find
the per-RAID pools.

Extend rf_pool_init() to now populate a per-RAID wchan value that is
unique to each pool for a given RAID device.

TODO: Complete the analysis of the minimum number of items that are
required for each pool to allow IO to progress (i.e. so that a request
for pool resources can always be satisfied), and dynamically scale
minimum pool sizes based on RAID configuration.

Mostly merge changes from HEAD upto 20200411

fix the function pointer and callback mess:
- callback functions return 0 and their result is not checked; make them void.
- there are two types of callbacks and they used to overload their parameters
  and the callback structure; separate them into "function" and "value"
  callbacks.
- make the wait function signature consistent.

Sync with HEAD

- Change the allocation macros to be more like function calls
- Change sizeof(type) -> sizeof(*variable)
- Use macros for the long buffer length allocations
- Remove "bit polishing" memsets() -- do them only once
- Remove unnecessary casts

Thanks to oster@ for finding bugs and testing.

convert regionBufferPool.mutex/cond and parityBufferPool.mutex/cond
to kmutex/cv.

convert regionInfo[regionID].mutex to a kmutex.

convert reintMutex to a kmutex.

convert parityLogDiskQueue.mutex to a kmutex/cv.

XXX: some splbio() usage to clean up here

finish porting mcpair users to kmutex, and fix a couple of declarations
in rf_netbsdkintf.c.  fixes i386/conf/ALL build.

Commit is split, to avoid a "too many arguments" protocol error.

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.)

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

iCleanup the RF_CREATE_PARAM3().  Middle two "arguments" were nothing
but 0 in all cases.

[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.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Catch up to -current.

Protect rf_PrintDAGList() in a few more places.  Thanks to Monroe Williams
on current-users for the patch.

Sync kqueue branch with -current.

add RCSIDs

Catch up to -current.

Catch up with -current. Fix some bogons in the sparc64 kbd/ms
attach code. cd18xx conversion provided by mrg.

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.

Catch up with -current.

update to -current

bzero -> memset

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Fix typo + cleanup a bit.

Make more 80-column friendly.  No functionality changes.

"fix" a serious problem with RF_AccTraceEntry_t tracerec stuff.
XXX the "fix" is incorrect, but that makes it consistent with
some of the other code here.  A this point you should *not* be
thinking about using this code. (At all.) (And I mean it.)

Nuke an unneeded #ifdef (__NetBSD__)

Nuke: #include "rf_threadid.h".

Nuke  RF_DECLARE_GLOBAL_THREADID, rf_setup_threadid(), rf_shutdown_threadid(),
and rf_assign_threadid().  rf_threadid.h, your days are numbered.

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.
