Add GDB qAttached support
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.
