 * Supported types:
69
 *
70
 * 'F'          filename
71
 * 'B'          block device name
72
 * 's'          string (accept optional quote)
73
 * 'O'          option string of the form NAME=VALUE,...
74
 *              parsed according to QemuOptsList given by its name
75
 *              Example: 'device:O' uses qemu_device_opts.
76
 *              Restriction: only lists with empty desc are supported
77
 *              TODO lift the restriction
78
 * 'i'          32 bit integer
79
 * 'l'          target long (32 or 64 bit)
80
 * 'M'          just like 'l', except in user mode the value is
81
 *              multiplied by 2^20 (think Mebibyte)
82
 * 'o'          octets (aka bytes)
83
 *              user mode accepts an optional T, t, G, g, M, m, K, k
84
 *              suffix, which multiplies the value by 2^40 for
85
 *              suffixes T and t, 2^30 for suffixes G and g, 2^20 for
86
 *              M and m, 2^10 for K and k
87
 * 'T'          double
88
 *              user mode accepts an optional ms, us, ns suffix,
89
 *              which divides the value by 1e3, 1e6, 1e9, respectively
90
 * '/'          optional gdb-like print format (like "/10x")
91
 *
92
 * '?'          optional type (for all types, except '/')
93
 * '.'          other form of optional type (for 'i' and 'l')
94
 * 'b'          boolean
95
 *              user mode accepts "on" or "off"
96
 * '-'          optional parameter (eg. '-f')
