With this patch QEMU handles qAttached request from gdb. When QEMU
replies 1, GDB sends a "detach" command at the end of a debugging
session otherwise GDB sends "kill".
The default value for qAttached is 1 on system emulation and 0 on user
emulation.
Based on original version by Fabien Chouteau.
The requirements described in this patch are implemented by "Add GDB
qAttached support".
This reverts commit 00e94dbc7fd0110b0555d59592b004333adfb4b8.

Change -numa option like following as Paolo suggested:
-numa node,nodeid=0,cpus=0-1 \
-numa mem,nodeid=0,size=1G
This new option will make later coming memory hotplug better.
And this new option is implemented using OptsVisitor.
