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.

arguments. With these fixes in place we can now switch the boot word to use (encode-bootpath) which means that the bootpath and
bootarg properties are now set exactly the same when executing boot and/or load.

hierarchy is correct, we can simply pass an ihandle into the loader and it will work correctly regardless of whether it is being
invoked on an entire disk, partition or individual file.
In order to test the new code, start by switching the Fcode loader over to the new infrastructure for testing on SPARC64. Note
this patch also contains a correction to load-base on SPARC which was being set to a value other than 0x4000 which is the
documented default.

Also use handle-text in " instead of the hand crafted version. This fixes

Annexe H.8, "User interface name changes", "select-dev" and
"unselect-dev" have been obsoleted and replaced by "open-dev" and
"device-end".
But some scripts (like BootX) are using the obsoleted name, so we need
to
define them.

CHRP boot method.
It finds the CHRP bootscript using the file attribute 'tbxi' and
the blessed directory.
This method allows to boot easily Fedora (the bitness detection is done
by the script and yaboot is called with the according yaboot.conf) but
openSUSE is broken (you have to use "boot cd:,\suseboot\yaboot")
Debian works well (as usual...).
The openSUSE needs the missing forth words: "load" and "go".
The MacOS bootloader (BootX) is also loaded automatically but forth
script is too complex to be executed correctly.
