d49f626ed0 qmp: don't make -qmp disable the default monitor
Instead, we introduce a default_qmp flag.  We don't use it yet, but will in the
next patch.

This has a user-visible impact as specifying just -qmp will now also show a

8af8ce4d61 tap: invoke downscript when we exit abnormally
Right now, downscript is not invoked reliably.  If you execute 'quit' from the
monitor, it won't be invoked.

This fixes that by converting tap to use an exit_notifier to execute the
downscript.  In this case, allowing an exit notifier to include state is
critically important for the conversion.

d7234f4d7e Convert atexit users to exit_notifier
All of these users have global state so we really don't see a benefit from
exit_notifier.  However, using exit_notifier means that there's one less

3af12c86d9 sdl: use mouse mode notifier
Today we poll the mouse mode whenever there is a mouse movement.  There is a
subtle usability problem with this though.

If we're in relative mode and grab is enabled, when we change to absolute mode,
we break grab.  This gives a user a seamless transition when the new pointer
is enabled.

But because we poll for mouse change, this grab break won't occur until the user
attempts to move the mouse.  By using notifiers, the grab break happens as soon
as possible.

eb2e259d95 Add kbd_mouse_has_absolute()
kbd_mouse_is_absolute tells us whether the current mouse handler is an absolute
device.  kbd_mouse_has_absolute tells us whether we have any device that is
capable of absolute input.

This lets us tell a user that they have configured an absolute device but that
the guest is not currently using it.

6fef28ee6e Rewrite mouse handlers to use QTAILQ and to have an activation function
And convert usb-hid to use it (to avoid regression with bisection)

Right now, when we do info mice and we've added a usb tablet, we don't see it
until the guest starts using the tablet.  We implement this behavior in order
to provide a means to delay registration of a mouse handler since we treat
the last registered handler as the current handler.

This is a usability problem though as we would like to give the user feedback
that they've either 1) not added an absolute device 2) there is an absolute
device but the guest isn't using it 3) we have an absolute device and it's
active.

By using QTAILQ and having an explicit activation function that moves the
handler to the front of the queue, we can implement the same semantics as
before with respect to automatically switching to usb tablet while providing
the user with a whole lot more information.

7a5e583811 do not use qemu_event_increment outside qemu_notify_event
qemu_notify_event in the non-iothread case is only stopping the current
CPU.  However, if the CPU is idle and the main loop is in the select
call then a call to qemu_event_increment is needed too (as done in
host_alarm_handler).  Since in general one doesn't know whether the CPU
is executing or not, it is a safe bet to always do qemu_event_increment.

Another way to see it: after this patch qemu_event_increment is the
"common part" of qemu_notify_event for both the CONFIG_IOTHREAD and
!CONFIG_IOTHREAD cases, which makes sense.
