984fa1d4c6 EXT2 backed by block device
WARNING: THIS BREAKS PARTITIONS

Until I get partition maps and can produce device entries like
/dev/hda1, partitions will be broken, so DON'T TRY TO BUILD AN IMAGE
WITH THE IMAGE BUILDER.

Hopefully this is all rectified in under 24 hours...

ed03c517ad More real module loading
Still need to do proper loading of the ELF sections somewhere, but other
than that, we've got a standard interface now. Needs a syscall so we can
write an insmod or something like that.

cc4391d783 Initial work on modules
There's a lot here, so let's through it:
- Lots of work to include a symbol table in the kernel. We can't rely on
  our bootloader to give us our own ELF information, so we do this
  separately. This probably should be changed to output a C source
  rather than assembly, but that's a TODO.
- Makefile can now generate modules. It works basically the same way any
  other kernel object works, expect with a slightly different linking
  scheme.
- Commands have been added to the debug shell to load modules, but they
  don't work yet - still need to get through relocation and linking.
- Commands have been added to the debug shell to print the symbol list,
  as well as print symbol values (but note that printing symbol values
  is kinda dangerous if you don't know what they are, so don't just go
  printing things willy-nilly).
