Defer multiboot device parsing until we're in compressed part.

Browse source 
* grub-core/boot/i386/pc/lnxboot.S: Remove setting dos_part and
	bsd_part. setdevice has fallen into disuse.
	* grub-core/boot/i386/pc/startup_raw.S (dos_part): Removed.
	(bsd_part): Likewise.
	(boot_dev): New variable.
	(multiboot_trampoline): Don't parse multiboot device.
	Pass multiboot device in %edx.
	* grub-core/disk/i386/pc/biosdisk.c (GRUB_MOD_INIT): Parse
	grub_boot_device.
	* grub-core/kern/i386/pc/init.c (grub_machine_get_bootlocation):
	Likewise.
	* grub-core/kern/i386/pc/startup.S: Save edx.
	(grub_boot_drive): Removed.
	(grub_install_dos_part): Likewise.
	(grub_install_bsd_part): Likewise.
	(grub_boot_device): New variable.
	* include/grub/i386/pc/kernel.h (grub_install_dos_part): Removed.
	(grub_install_bsd_part): Likewise.
	(grub_boot_drive): Likewise.
	(grub_boot_device): New variable.
	* include/grub/offsets.h (GRUB_KERNEL_I386_PC_INSTALL_DOS_PART):
	Removed.
	(GRUB_KERNEL_I386_PC_INSTALL_BSD_PART): Likewise.
	(GRUB_KERNEL_I386_PC_REED_SOLOMON_REDUNDANCY): Moved lower.
