From: Jan Kiszka <jan.kis...@siemens.com> 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.

Long pending in my queue. Hope we can finally get these two in via
trivial (that's what they are).
