allow the loading of kernels from a NetBSD file system by a RISC-OS-based
bootloader. Currently, there's just about enough functionality to allow
BtNetBSD (and hence presumably boot32 on systems where it works) to load
a kernel. This code has the great advantages over our existing UnixFS
that we actually have the source and can compile it under NetBSD.
In particular avoid calling fclose() again once it has failed.
Also multply 'oreg' by 2 once we modify the file - so we know when to
unlink it on error.

I'm not at all sure EOF handling is correct anyway - but it probably only
affects the last line of a file (and maybe last lines without \n).
In particular I suspect that 'ungetc(EOF, file)' doesn't do the expected
thing, and that fseek() needs to be preceeded by clearerr(). But life it short.
1) Add an md_post_extract() function. This function is called after
extracting the sets, and allows the arch to do something at that time.
In the case of prep, it is much easier to install the bootcode after all
the sets are extracted, so we do it in md_post_extract(). Added empty
md_post_extract() functions to all other arches so they compile.
2) Add md_mbr_use_wholedisk() and md_check_mbr(). In edit_mbr() I have
split off the code that uses the whole disk for NetBSD, into the
mbr_use_wholedisk() function. On most ports that use mbr.c, I made
md_mbr_use_wholedisk() just call that and return. On prep we create the
magical prep boot partition here. The md_check_mbr() function allows the
arch to add additional checks after the user had manually edited the MBR
to make sure the choices he made allow NetBSD to function. Added a dummy
routine to all mbr.c using arches.
3) Added code to bsdlabel.c to create a partition of type boot if
PART_BOOT is defined, but BOOT_SIZE is not defined. Also added two more
globals "bootsize" and "bootstart" which must be seeded in order to do
so. This is done on prep in md_check_mbr().
4) Added MBR_PTYPE_PREP to the list of MBR partitions.
5) Made the prep port actually install sanely. It now creates a prep
boot partition, labels it correctly, installs all the sets, and then runs
mkbootimage and dd's the bootimage into the prep partition. The result
is a prep installer that creates a bootable NetBSD installation
automatically.
6) Edited the prep menus and messages files to add new labels. In the
case of the translated files, I just added the words in english for
someone to translate later.
I tried to xcompile a few arches to make sure I didn't break anything,
but I could have missed something. Please let me know if I have broken
your arch in any way. I'll watch the autobuilds for the next few days
too. For all ports other than prep there should be no functional changes
at all.

Use the opt_ah.h for the provided HAL to get options like AH_REGOPS_FUNC.
Add AH_REGOPS_FUNC to a few opt_ah.h that don't have it in this version
of the HAL but need it. (The next version from Sam should have this fixed
in it. If it doesn't, then we'll have to take care at import time.)
Ultimately, this should make future imports even easier, and individual ports
should not have to worry about whether AH_REGOPS_FUNC is properly defined or
not, since the opt_ah.h will just take care of it automatically.
Ok'd by dyoung@.
can automatically use the AH_XXX options that the HAL was built, without
requiring additional machine-specific configuration.
A follow up commit will activate this change.
