NetBSD/sys/dev/raidframe/rf_debugMem.h
oster ee19b085aa - first kick at a major reworking of RAIDframe's memory allocation code:
- all freelists converted to pools
  - initialization of structure members in certain cases where
	code was relying on specific allocation and usage properties
	to keep structures in a "known state" (that doesn't work with
	pools!).
  - make most pool_get() be "PR_WAITOK" until they can be analyzed
	further, and/or have proper error handling added.
  - all RF_Mallocs zero the space returned, so there is no difference
	between RF_Calloc and RF_Malloc.  In fact, all the RF_Calloc()'s
	do is tend to do is get things horribly confused.
	Make RF_Malloc() the "general memory allocator", with
	RF_MallocAndAdd() the "general memory allocator with
	allocation list".
  - some of these RF_Malloc's et al. are destined to disappear.
  - remove rf_rdp_freelist entirely (it's not used anywhere!)
  - remove: #include "rf_freelist.h"
  - to the files that were relying on the above, add: #include "rf_general.h"
  - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy
	about the loss of: #include "rf_freelist.h".

This shrinks an i386 GENERIC kernel by approx 5K.  RAIDframe now
weighs in at about 162K on i386.
