Continue the " - . - 8" purge. Specifically:
add rd, pc, #foo - . - 8 -> adr rd, foo
ldr rd, [pc, #foo - . - 8] -> ldr rd, foo
Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.
Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.

* Rewrite the 32-bit ARM pte.h based on the ARM architecture manual.
Significant cleanup, here, including better PTE bit names.
* Add XScale PTE extensions (ECC enable, write-allocate cache mode).

doing this, two bugs (as a result of typos) were fixed in

Clean up Netwinder bootstrap:
* Put the code that runs with the MMU off in a separate section (.start).
* Use a linker script to set the VMA/LMA appropriately for each section.
* Fix kernel page table allocation and mapping of kernel text/data/bss.
...and now that kernel images > 2MB work:
* Add SYMTAB_SPACE to the GENERIC kernel so that we have DDB symbols.
* Use dbsym to load the kernel's DDB symbol area.

- Move more contents of various <machine/vmparam.h> files into
<arm/arm32/vmparam.h> (mostly the stuff that's tied to the pmap
implementation).
- Since the MMU definitions in pte.h are specific to ARM processors
that support 32-bit mode, move pte.h to <arm/arm32/pte.h>.
- Make the Netwinder startup file build again (use PT_B|PT_C, rather
than PT_CACHEABLE, since the latter expands to a variable these days).
