 1.8  23-Jul-2021  oster 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.
 1.7  10-Oct-2019  christos branches: 1.7.12;
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.
 1.6  11-Dec-2005  christos branches: 1.6.164;
merge ktrace-lwp.
 1.5  03-Mar-2004  oster - cleanup unneeded 'row' from RF_CallbackDesc_s.
- remove callbackArg2 from RF_CallbackDesc_s -- it is only ever set,
never read.
- now that this is done, all callbacks should only take a single argument,
and we can simplify things further.
 1.4  04-Oct-2001  oster branches: 1.4.18;
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.
 1.3  05-Feb-1999  oster branches: 1.3.20; 1.3.22; 1.3.24;
Phase 2 of the RAIDframe cleanup. The source is now closer to KNF
and is much easier to read. No functionality changes.
 1.2  26-Jan-1999  oster 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.
 1.1  13-Nov-1998  oster 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.
