3330f2e126 Fix a thinko in packages/mac-parts and then rework the open method so it more accurately reflects the CHRP boot specification. Also add seek limits
to each partition type, since some existing code uses this to detect bootloader code. This fixes the quik bootloader problem for PPC as reported by 
Aurelian Jarno.

a5511ad95c Currently the dir word works by using /packages/misc-files to open a directory in a similar way to a file and then
special-casing directory actions. This is wrong in that in order to list the contents of a directory, open-dev must return true 
for any device which contains a valid filesystem, regardless of whether or not the supplied arguments reference a valid path.

This causes us a problem because in order to implement multiple references in boot-device correctly, we have to fail if we open 
a specific device with invalid arguments (such as a non-existent file reference). This patch therefore makes the following changes:

1) Create a static method in each of the filesystem packages to implement dir
2) Enhance the partition/disk handlers to record the phandle of any detected filesystem during open
3) Create a new dir method in the partition/disk handlers which invokes the static dir method for the currently detected 
filesystem

Hence we can now open a raw device/partition and invoke dir on its filesystem without having to open a specific file-reference 
first. Following shortly is a patch to switch the main dir word over to use this new system.

5ed6ff34fc Move the separate ISO9660 handler into a new /packages/iso9660-files package in preparation for some future work. Based heavily
on Laurent's original patch posted to the list.

3d7832bba9 Implement a basic C loader function in load.c that tries to load each supported executable file format. Now that the ihandle
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.

c6a9039103 Fix partition string parsing code so that it correctly handles boot strings beginning with a comma of the form
<device>,\path\to\file. This fixes all outstanding issues with PPC.

cdrom - deblocker - disk-label - (misc-files | sun-parts | pc-parts | mac-parts)
7fc4e304c3 As documented on the mailing lists, change the interposition order of the disk packages from:
cdrom -> deblocker -> disk-label -> (misc-files | sun-parts | pc-parts | mac-parts) 

to:

cdrom -> deblocker -> disk-label -> (sun-parts | pc-parts | mac-parts) -> misc-files 

This makes the overall code much simpler, since instead of passing get-info structures between the different layers to work out 
the current device offset, each package can simply maintain its own offsets and bubble them back up to the parent.

There are also many, many bugfixes present is patch, some of which are given below:

- Add debugging in /packages/misc-files, augment debugging in all other disk packages
- Fix alignment issue in /packages/pc-parts so it works correctly on strictly align archs, e.g. SPARC64
- Fix parsing of [<id>,][filename] arguments to load (in preparation for next patch set)
- Fix byte-swapping issues in /packages/mac-parts (in theory it should now work regardless of endian)

dbf16392cc Refactoring of the OpenBIOS source code, as discussed on the mailing list. The primary aim of this process is to try and arrange
the source files into a structure whereby it is easier to find the relationship between a forth package word and its C 
implementation, while also creating a libopenbios library into which more common code from the arch/ tree can eventually be 
moved.
