x86_emu_debug.diff:
Change DEBUG for the emulator to DEBUG_EMU to avoid conflicts with DEBUG for log levels.

loglevel.diff:
Remove BIOS_EMERG, BIOS_ALERT, BIOS_CRIT, BIOS_NOTICE, BIOS_NEVER
I didn't change their numerical values. They were rarely used.
BIOS_EMERG, BIOS_ALERT, BIOS_CRIT -> BIOS_ERR
BIOS_NOTICE -> BIOS_INFO
BIOS_NEVER -> BIOS_SPEW+1

loglevel2.diff:
BIOS_ERR -> ERROR
BIOS_WARNING -> WARNING
BIOS_INFO -> INFO
BIOS_DEBUG -> DEBUG
BIOS_SPEW -> SPEW
For 80 character line aficionados, this puts most of the lines back, since printk_debug(...) is about the same length as printk(DEBUG, ...)

I didn't change llshell in any of these patches. It would be easy to add.

Abuild tested.
