Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

remove checks for failure after memory allocation calls that cannot fail:

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Some PICs have the capability to define the interrupt's polarity (OpenPIC
for example). So the accepted interrupt types have been extended to:
- IST_EDGE_FALLING (which is the same as IST_EDGE)
- IST_EDGE_RISING (new)
- IST_LEVEL_LOW (is the same as IST_LEVEL)
- IST_LEVEL_HIGH (new)
Old code will continue to work without modification.

Add support to ofppc for the IBM 7044-270 machine.  This is a POWER3-II
based machine.  Currently the kernel to run on this machine is
incompatible with the standard GENERIC kernel, so for now, we have a
separate GENERIC_B64. Eventually, I hope to combine the two.

Please note, this is a port of 32bit ofppc, not a powerpc64 port.

Thanks to Matt Thomas and Kevin Bowling for helping to make this port
possible.

Summary of changes:

Change ofwpci to use the ofmethod config for configuring the PCI bus,
rather than indirect configuration.
Move the wiring of the interrupt controllers from at the start of the
boot, into the configuration of the first PCI bus.
Rewrite the map_isa_ioregs() hack to work on a machine without BATs
Fix a ton of bugs in the genofw_find_pics routine, and in the map_space code.
Split the pic_openpic into openpic_common and pic_openpic.
Create a new pic_distopenpic driver, for the distributed openpic found on
some newer IBM machines.
Fix a bad panic in pmap_extract on 64bit bridge mode

Fix the endless stream of 7's problem on i8259-like interrupt controllers
once and for all.  The i8259 does not like to be read in a loop, when an
interrupt comes in, it will return a valid value, however, if you keep
reading it until there are no outstanding interrupts, it will return 7
(which is the lpt interrupt).  Change the pic handler to give an argument
to the get_irq functions of mode, which indicates if this is the first
time we are asking, or if we are just rechecking in a loop.  Non-i8259
handlers can safely ignore this argument.

Tested to fix the stream of 7's problem on prep and ofppc.  Got rid of
the nasty hack in ofppc with this too, and the prep machine seems to take
less interrupts now, which is a good thing.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

- make setup_openpic() to have every SRC_VECTOR(irq) register a value
  0x8000'0000 during initialization.  opic_establish_irq() will assign
  acutual usage values later on.
- note a comment describing that writing S1C bit for OPENPIC_CONFIG
  register should bring the sane initial operation state.  #if-0'ed out
  this time since it remains unknown wether every OpenPIC compliant
  controller behave in the same way.
- nuke struct openpic_ops which contains enable_mask for no use.

Move the functions down from openpic.c into pic_openpic.c, as there
really is no need to have them over there when all the interrupt routines
will be using pic_openpic.c
Change the openpic setup to set all the irqs except 0 to negative polarity.
Set the spurious vector reg to 0xff.
Emit a nice printf showing the version of the openpic, and getrid of the
maxint thing.
Add a global, primary_pic, so machines can elect any registered pic as
the primary interrupt controller.
Clean up a few nits in pic_prepivr to make it more similar to the openpic
one, add a prototype for the setup_prepivr function, etc etc.
