 * Supported types:

 *

 * 'F'          filename

 * 'B'          block device name

 * 's'          string (accept optional quote)

 * 'O'          option string of the form NAME=VALUE,...

 *              parsed according to QemuOptsList given by its name

 *              Example: 'device:O' uses qemu_device_opts.

 *              Restriction: only lists with empty desc are supported

 *              TODO lift the restriction

 * 'i'          32 bit integer

 * 'l'          target long (32 or 64 bit)

 * 'M'          just like 'l', except in user mode the value is

 *              multiplied by 2^20 (think Mebibyte)

 * 'o'          octets (aka bytes)

 *              user mode accepts an optional T, t, G, g, M, m, K, k

 *              suffix, which multiplies the value by 2^40 for

 *              suffixes T and t, 2^30 for suffixes G and g, 2^20 for

 *              M and m, 2^10 for K and k

 * 'T'          double

 *              user mode accepts an optional ms, us, ns suffix,

 *              which divides the value by 1e3, 1e6, 1e9, respectively

 * '/'          optional gdb-like print format (like "/10x")

 *

 * '?'          optional type (for all types, except '/')

 * '.'          other form of optional type (for 'i' and 'l')

 * 'b'          boolean

 *              user mode accepts "on" or "off"

 * '-'          optional parameter (eg. '-f')
