 * Supported types:
68
 *
69
 * 'F'          filename
70
 * 'B'          block device name
71
 * 's'          string (accept optional quote)
72
 * 'O'          option string of the form NAME=VALUE,...
73
 *              parsed according to QemuOptsList given by its name
74
 *              Example: 'device:O' uses qemu_device_opts.
75
 *              Restriction: only lists with empty desc are supported
76
 *              TODO lift the restriction
77
 * 'i'          32 bit integer
78
 * 'l'          target long (32 or 64 bit)
79
 * 'M'          just like 'l', except in user mode the value is
80
 *              multiplied by 2^20 (think Mebibyte)
81
 * 'o'          octets (aka bytes)
82
 *              user mode accepts an optional T, t, G, g, M, m, K, k
83
 *              suffix, which multiplies the value by 2^40 for
84
 *              suffixes T and t, 2^30 for suffixes G and g, 2^20 for
85
 *              M and m, 2^10 for K and k
86
 * 'f'          double
87
 *              user mode accepts an optional G, g, M, m, K, k suffix,
88
 *              which multiplies the value by 2^30 for suffixes G and
89
 *              g, 2^20 for M and m, 2^10 for K and k
90
 * 'T'          double
91
 *              user mode accepts an optional ms, us, ns suffix,
92
 *              which divides the value by 1e3, 1e6, 1e9, respectively
93
 * '/'          optional gdb-like print format (like "/10x")
94
 *
95
 * '?'          optional type (for all types, except '/')
96
 * '.'          other form of optional type (for 'i' and 'l')
97
 * 'b'          boolean
98
 *              user mode accepts "on" or "off"
99
 * '-'          optional parameter (eg. '-f')
