  SVN rev 197442 on 2009-09-23 20:13:36Z by jkim
  
  - Use spin lock instead of default mutex for safety.  INT/IRET instructions
  save/clear/restore flags but emulated flags have no effect on the host.
  I believe BIOS writers never meant to run their code in emulated
  environment with interrupt enabled. :-)
  - Use memcpy(3) instead of copying individual members.  I believe struct
  x86regs was intentionally copied from the first half of struct x86emu_regs
  for this very purpose.
  - Fix some style nits and consistencies.
