clean up, get it closer to compiling. (Note that this change includes
...
a change marked XXX, where gcc -Wall pointed out a bit of the original
code that looked wrong. The jury's still out on whether or not it was
really wrong, but it looked _very_ suspicious.)

Import sys/arch/arm32/{shark,ofw} bits of the Digital Network Appliance
...
Reference Design NetBSD source code, obtained from the pages under
http://www.research.digital.com/SRC/iag . Some of this code (badly)
needs to be cleaned up, and as-is it doesn't compile. However, getting
it in the tree is a start.

Use a separate variable to indicate whether the fault is from USR mode
...
or not rather than orring in a USER bit into the fault code variable.
This simplifies the fault switch statement and some of the addition
checks that are made of the fault code.
Move the printing of data abort information out into a separate function
rather then duplicating a lot of similar printf() statements.
Removed the fault_code variables from the prefetch abort handler as it
is not actually used for anything.

Major overhaul of pagetable handing.
...
Page tables no longer occupy space in the processes vm_map. This
means that page tables can now be allocated from pmap_enter() when the
first entry is made in the page table rather than relying on taking
a section fault and faulting in a page table. This also lowers
the overheads in creating and deleting page tables and simplfies
cpu_fork().
A result of this change is that problems with mapping zero page and
an associated pagetable when execing from a shared vm_map disappear
fixing PR5178.
