    x86 realmode: Use x86emu register file + defines
    
    By using the (global) register file as defined by x86emu,
    we can use the same register access for YABEL and realmode
    interrupt handlers.
    
    - the x86 realmode interrupt handlers changed in signature
    - to access registers, use X86_$REGNAME now (eg. X86_EAX)
    - x86_exception_handler still uses struct eregs *regs to
      avoid spilling the x86emu register file stuff everywhere
