* Supported types:

* 'S' it just appends the rest of the string (accept optional quote)
* 'O' option string of the form NAME=VALUE,...
* parsed according to QemuOptsList given by its name
* Example: 'device:O' uses qemu_device_opts.
* Restriction: only lists with empty desc are supported
* TODO lift the restriction
* 'i' 32 bit integer
* 'l' target long (32 or 64 bit)
* 'M' Non-negative target long (32 or 64 bit), in user mode the
* value is multiplied by 2^20 (think Mebibyte)
* 'o' octets (aka bytes)
* user mode accepts an optional E, e, P, p, T, t, G, g, M, m,
* K, k suffix, which multiplies the value by 2^60 for suffixes E
* and e, 2^50 for suffixes P and p, 2^40 for suffixes T and t,
* 2^30 for suffixes G and g, 2^20 for M and m, 2^10 for K and k
* 'T' double
* user mode accepts an optional ms, us, ns suffix,
* which divides the value by 1e3, 1e6, 1e9, respectively
* '/' optional gdb-like print format (like "/10x")
*
* '?' optional type (for all types, except '/')
* '.' other form of optional type (for 'i' and 'l')
* 'b' boolean
* user mode accepts "on" or "off"
* '-' optional parameter (eg. '-f')
