This patch provides HMP equivalent of QMP query-memory-devices command. By this command "info memory-devices", user can know all information about hotpluggable memmory device such as id. With id of devices, hot removing hotpluggable memory devices becomes possible by command 'device_del'.

Change log v1 -> v2:
1. fix bug that accessing info->dimm when MemoryDeviceInfo is not PCDIMMDevice.
2. use enum to replace "dimm", and lookup type name in MemoryDeviceInfoKind_lookup[] instead of opencodding it.

I'd very much prefer

    for (elem = list; elem; elem = elem->next) {

because that concentrates the loop control in one place.

Even better, imitate existing code to blend in, like this:

    MemoryDeviceInfoList *info_list = qmp_query_memory_devices(&err);
    MemoryDeviceInfoList *info;
    MemoryDeviceInfo *value;

    for (info = info_list; info; info = info->next) {
        value = info->value

When writing for human readers, please follow the ancient custom to
separate words by space: "Memory device", not "MemoryDevice".

The union discriminator info->kind is common to all members.  Printing
it should go before the switch, along with the header.
