Read device configuration from file. This approach is useful when
you want to spawn QEMU process with many command line options but
you don't want to exceed the command line character limit.

Like -set and -readconfig, it would not really be too hard to extend -writeconfig to parsing mechanisms other than QemuOpts. However, the uses of -writeconfig are substantially more limited, as it is generally easier to write the configuration by hand in the first place. In addition, -writeconfig does not even try to detect cases where it prints incorrect syntax (for example if values have a quote in them, since qemu_config_parse does not support any kind of escaping. Just remove it.
