This patch converts biosdisk into a module.
In the future, maybe we can also move some of the grub_biosdisk_* functions
in kern/i386/pc/startup.S into this module, but it seems the build system
reacts very adversely to modules containing standalone assembly files, so
I fixed one bug (see followup) and gave up.
