Currently when disabling login in VNC, the password is cleared out and the
authentication protocol is forced to AUTH_VNC. If you're using a stronger
authentication protocol, this has the effect of downgrading your security
protocol.
Fix this by only changing the authentication protocol if the current
authentication protocol is AUTH_NONE. That ensures we're never downgrading.

Replace device_init() with generalized type_init().
While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

For any modifier key (shift, ctrl, alt) still pressed on disconnect
inject a key-up event into the guest. The vnc client is gone, it will
not do that, so qemu has to do it instead.
Without this keys will get stuck, making the guest act in weird ways
after reconnecting. Reproducer: exit vnc client via Alt-F4, guest
continues to see the pressed alt key and will not react to key events
in any useful way until you tap the alt key once to unstuck it.

VNC clients send a shared flag in the client init message. Up to now
qemu completely ignores this. This patch implements shared flag
handling. It comes with three policies: By default qemu behaves as one
would expect: Asking for a exclusive access grants exclusive access to
the client connecting. There is also a desktop sharing mode which
disallows exclusive connects (so one forgetting -shared wouldn't drop
everybody else) and a compatibility mode which mimics the traditional
(but non-conforming) qemu behavior.

vnc assumes that the screen width is a multiple of 16 in several places.
If this is not the case vnc will overrun buffers, corrupt memory, make
qemu crash.
This is the minimum fix for this bug. It makes sure we don't overrun the
scanline, thereby fixing the segfault. The rendering is *not* correct
though, there is a black border at the right side of the screen, 8
pixels wide because 1400 % 16 == 8.

There are scenarios on Linux with some SDL versions where
handle_activation is continuous invoked with state = SDL_APPINPUTFOCUS
and gain = 0 while we grabbed the input. This causes a ping-pong when we
grab the input after an absolute mouse entered the window.
As this sdl_grab_end was once introduced to work around a Windows-only
issue (0294ffb9c8), limit it to that platform.

This reverts commit 6bb816031f.
SDL_WM_GrabInput does not reliably bail out if grabbing is impossible.
So if we get here, we already lost and will block. But this can no
longer happen due to the check in sdl_grab_start. So this patch became
obsolete.

There are three important remarks in relation to the non-qapi command:
1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc'
commands to return an error when qemu is built without VNC support
(ie. --disable-vnc). The non-qapi command would return the OK
response in QMP and no response in HMP
2. The qapi version explicitly marks the fields 'host', 'family',
'service' and 'auth' as optional. Their are not documented as optional
in the non-qapi command doc, but they would not be returned if
vnc support is disabled. The qapi version maintains the same
semantics, but documents those fields correctly
3. The 'clients' field, which is a list, is marked as optional but is
always returned. If there are no clients connected an empty list
is returned. This is not the Right Way to this in the qapi but it's
how the non-qapi command used to work

Today, when notifying a VM state change with vm_state_notify(),
we pass a VMSTOP macro as the 'reason' argument. This is not ideal
because the VMSTOP macros tell why qemu stopped and not exactly
what the current VM state is.
One example to demonstrate this problem is that vm_start() calls
vm_state_notify() with reason=0, which turns out to be VMSTOP_USER.
This commit fixes that by replacing the VMSTOP macros with a proper
state type called RunState.

Not grabbing the input means that special keys like ALT+TAB are still
handled by the host. Improve the usability by grabbing input once the
mouse is inside the guest screen, provided the SDL window has the input
focus. Release it again when the mouse is moved to any border. Also grab
the input when we gain the input focus and the mouse is within the
screen limits.
