  63  * Supported types:

  65  * 'F'          filename
  66  * 'B'          block device name
  67  * 's'          string (accept optional quote)
  68  * 'O'          option string of the form NAME=VALUE,...
  69  *              parsed according to QemuOptsList given by its name
  70  *              Example: 'device:O' uses qemu_device_opts.
  71  *              Restriction: only lists with empty desc are supported
  72  *              TODO lift the restriction
  73  * 'i'          32 bit integer
  74  * 'l'          target long (32 or 64 bit)
  75  * 'M'          just like 'l', except in user mode the value is
  76  *              multiplied by 2^20 (think Mebibyte)
  77  * 'f'          double
  78  *              user mode accepts an optional G, g, M, m, K, k suffix,
  79  *              which multiplies the value by 2^30 for suffixes G and
  80  *              g, 2^20 for M and m, 2^10 for K and k
  81  * 'T'          double
  82  *              user mode accepts an optional ms, us, ns suffix,
  83  *              which divides the value by 1e3, 1e6, 1e9, respectively
  84  * '/'          optional gdb-like print format (like "/10x")
  85  *
  86  * '?'          optional type (for all types, except '/')
  87  * '.'          other form of optional type (for 'i' and 'l')
  88  * 'b'          boolean
  89  *              user mode accepts "on" or "off"
  90  * '-'          optional parameter (eg. '-f')
