[Bug breakpoints/15434] Dprintf uses a synchronous 'continue' even in non-stop mode

To see the problem, I suggest you do the following:

(gdb) set target-async on
(gdb) set non-stop on
(gdb) r&

Then type:
 interrupt

The thread should be interrupted.  This is the expected behavior because in
non-stop, you can still talk to GDB when the inferior is running.

The bad behavior is from:

(gdb) set target-async on
(gdb) set non-stop on
(gdb) dprintf 8,"go\n"
(gdb) r&

Then, when you type interrupt, GDB will ignore it because it did a 'continue'
at the dprintf, instead of a 'continue&'.  You must then do ^C to get control
back.
