 * Supported types:
82
 *
83
 * 'F'          filename
84
 * 'B'          block device name
85
 * 's'          string (accept optional quote)
86
 * 'O'          option string of the form NAME=VALUE,...
87
 *              parsed according to QemuOptsList given by its name
88
 *              Example: 'device:O' uses qemu_device_opts.
89
 *              Restriction: only lists with empty desc are supported
90
 *              TODO lift the restriction
91
 * 'i'          32 bit integer
92
 * 'l'          target long (32 or 64 bit)
93
 * 'M'          Non-negative target long (32 or 64 bit), in user mode the
94
 *              value is multiplied by 2^20 (think Mebibyte)
95
 * 'o'          octets (aka bytes)
96
 *              user mode accepts an optional T, t, G, g, M, m, K, k
97
 *              suffix, which multiplies the value by 2^40 for
98
 *              suffixes T and t, 2^30 for suffixes G and g, 2^20 for
99
 *              M and m, 2^10 for K and k
100
 * 'T'          double
101
 *              user mode accepts an optional ms, us, ns suffix,
102
 *              which divides the value by 1e3, 1e6, 1e9, respectively
103
 * '/'          optional gdb-like print format (like "/10x")
104
 *
105
 * '?'          optional type (for all types, except '/')
106
 * '.'          other form of optional type (for 'i' and 'l')
107
 * 'b'          boolean
108
 *              user mode accepts "on" or "off"
109
 * '-'          optional parameter (eg. '-f')
