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