have the /rtas node.
Make /rtas conditional to NewWorld Macs for now, while allowing to

This means that the ppc-softmmu would by default not have it,
except when using -M mac99. ppc64-softmmu would get it by default.

ofmem was fixed at 0x05400000, followed by the malloc zone. The latter was
bounded by the stack (now client stack), relative to the top of RAM.
An increase of RAM would therefore only enlarge the malloc zone.
Move the malloc zone below the client stack, with a fixed size of 2 MiB.
The size is derived from the memory map depicted in ofmem.c;
having a fixed size leaves room for memory claim'ed by clients
and by OpenBIOS.
v2:
* Through the preceding patch the malloc zone goes below the client stack
rather than below the stack. Adjust and prettify the illustration.

IEEE-1275 spec compliance.
This patch implements the following:
1) Fix bootpath/bootargs handling so that default values are read from NVRAM, and allow multiple space-separated values to be
specified.
2) With correct bootargs handling in place, move the ELF loader over to the new libopenbios unified loaders.
3) Remove all the loader code from all architecture directories sine we don't need it anymore.
4) Simplify the boot word so it invokes platform-specific code where required, then calls load and go as per the specification.
Tested on all my available images for SPARC32, SPARC64 and PPC, and compile-tested on x86.

This patch originally started as a fix for PPC, in that the NVRAM initialiser wasn't been run on startup (this is why printenv
on PPC always showed much much less than on SPARC). However, it also showed up some inconsistent logic for boot device
selection, which must also happen *before* boot is called in order for load to work correctly. With this patch applied, bootpath
and bootargs are set from boot-device and boot-args respectively on startup for SPARC32, SPARC64 and PPC.
Note: there is a small chance SPARC32 may break on some images - please let me know if it does.
