Change the parser to put the values into a QDict and pass them to a callback. qemu_config_parse's QemuOpts creation is itself turned into a callback function. This is useful for -readconfig to support keyval-based options; getting a QDict from the parser removes a roundtrip from QDict to QemuOpts and then back to QDict. Unfortunately there is a disadvantage in that semantic errors will point to the last line of the group, because the entries of the QDict do not have a location attached.
