  Log:
  IOCTL mapping layer Part I/II
  
  This adds a generic framework for mapping IOCTL requests (cmds) and
  attaching special processing functions. Instead of the former adhoc
  code using large switch statements e.g. in emulation/linux/linux_ioctl.c,
  the emulation layer registers a handler with the mappings for the request
  ranges it wants to handle specially. Devices can afterwards add there
  own mappings to support e.g. Linux specific IOCTLs.
  
  The first part adds the infrastructure, the second part converts the Linux
  emulation, dev/drm and dev/raid/aac.
