[Qemu-devel] [PATCH 15/19] Expand query-argv to include help string

["Daniel P. Berrange" <berrange@redhat.com>]

This expands the query-argv data format to include the help
string for each argument. This is not really very desirable
since the help strings are not in a predictable format for apps
to use. Ideally the full structured details about each argument
parameter would be included instead. This makes the data format
look like

    [
        {
            "name": "help",
            "help": "-h or -help     display this help and exit\n",
        },
        {
            "name": "M",
            "help": "-M machine      select emulated machine (-M ? for list)\n",
            "parameters": [
            ]
        },
    ]
