dependancy code would not be able to load any files if it needed
too.

* Fix a raft of warnings, printf and otherwise.
* Allocate the correct amount in mod_searchmodule to prevent an overflow.
* Fix the makefiles so they work outside my home directory (oops).

- Move some startup code from MD to MI sections
- Add a 'copyout' and some copyout-related functions. These will be
obsoleted when BTX is available for the 386 and the kernel load
area becomes directly addressable.
- Add the ability load an arbitrary file as a module, associating
and arbitrary type string with it. This can be used eg. for loading
splash-screen images etc.
- Add KLD module dependancy infrastructure. We know how to look for
dependancies inside KLD modules, how to resolve these dependancies
and what to do if things go wrong. Only works for a.out at the
moment, due to lack of an MI ELF loader. Attach KLD module information
to loaded modules as metadata, but don't pass it to the kernel (it
can find it itself).
- Load a.out KLD modules on a page boundary. Only pad the a.out BSS
for the kernel, as it may want to throw symbols away. (We might want
to do this for KLD modules too.)
- Allow commands to be hidden from the '?' display, to avoid cluttering
it with things like 'echo'. Add 'echo'.
- Bring the 'prompt' command into line with the parser syntax.
- Fix the verbose 'ls'; it was using an uninitialised stack variable.
- Add a '-v' flag to 'lsmod' to have it display module metadata as well
(not terribly useful for the average user)
- Support a 'module searchpath' for required modules.
- The bootstrap file on i386 is now called 'loader' to permit the
/boot directory to use that name.
- Discard the old i386 pread() function, as it's replaced by
arch_readin()

'three-stage' bootstrap.
There are a number of caveats with the code in its current state:
- The i386 bootstrap only supports booting from a floppy.
- The kernel and kld do not yet know how to deal with the extended
information and module summary passed in.
- PnP-based autodetection and demand loading of modules is not implemented.
- i386 ELF kernel loading is not ready yet.
- The i386 bootstrap is loaded via an ugly blockmap.
On the alpha, both net- and disk-booting (SRM console machines only) is
supported. No blockmaps are used by this code.
Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
