SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups

Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

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.

Some uncommitted poking around.  No functional change.

Sync w/ -current.

Include a bit more info about what's not happening with IOP.

file iop.c was added on branch scottr-mac68k-wscons on 1999-06-28 04:33:23 +0000

Include a bit more info about what's not happening with IOP.

Unfortunately, several changes that are intermingled:
- Add initial IOP support.  ADB doesn't work yet for me, but it's here so
  that others will be encouraged to work on it.  ADB_HW_IOP basically
  is configured as a NOP so that serial consoles will continue to work.
- Roll via1_intr and via2_intr into the intr.c scheme--this also required
  changing rtclock_intr to grovel the stack differently so that hardclock
  gets the right arguments and softclock() doesn't get all reentrant.
- Make via1 interrupts parallel to via2 interrupts--handlers get a pass-
  through pointer and we can register handlers.  Register via1 interrupt
  with intr_establish()--normally level 1, level 6 for A/UX scheme.
- Use intr_establish() to set real via2 interrupt handler instead of the
  hacked function pointer.
- Reorganize adb-direct interrupts so that a function call is removed.
- Implement A/UX interrupts for all Quadras right now.  We may need to
  special case some Quadras, but Linux folks are reporting success on
  several models.
- Fix intrnames to be accurate for the normal, PSC, and A/UX interrupt
  configurations.
