 * Supported types:
64
 *
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
 * 'b'          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
 * '-'          optional parameter (eg. '-f')
