virtio-rng-pci: fix transitional migration compat for vectors

In bad9c5a516 ("virtio-rng-pci: fix migration compat for vectors") I
fixed the virtio-rng-pci migration compatibility, but it was discovered
that we also need to fix the other aliases of the device for the
transitional cases.

backends/vhost-user: remove the ioeventfd check

While ioeventfds are needed for good performance with KVM guests it
should not be a gating requirement. We can run vhost-user backends using
simulated ioeventfds or inband signalling.

With this change I can run:

  $QEMU $OPTS \
    -display gtk,gl=on \
    -device vhost-user-gpu-pci,chardev=vhgpu \
    -chardev socket,id=vhgpu,path=vhgpu.sock

with:

  ./contrib/vhost-user-gpu/vhost-user-gpu \
    -s vhgpu.sock \
    -v

and at least see things start-up - although the display gets rotated by
180 degrees. Once lightdm takes over we never make it to the login
prompt and just get a blank screen.

virtio-net: clear guest_announce feature if no cvq backend

Since GUEST_ANNOUNCE is emulated the feature bit could be set without
backend support.  This happens in the vDPA case.

However, backend vDPA parent may not have CVQ support.  This causes an
incoherent feature set, and the driver may refuse to start.  This
happens in virtio-net Linux driver.

This may be solved differently in the future.  Qemu is able to emulate a
CVQ just for guest_announce purposes, helping guest to notify the new
location with vDPA devices that does not support it.  However, this is
left as a TODO as it is way more complex to backport.

Tested with vdpa_net_sim, toggling manually VIRTIO_NET_F_CTRL_VQ in the
driver and migrating it with x-svq=on.

ui/cocoa: user friendly characters for release mouse

While mouse is grabbed, window title contains a hint for the user what
keyboard keys to press to release the mouse. Make that hint text a bit
more user friendly for a Mac user:

 - Replace "Ctrl" and "Alt" by appropriate symbols for those keyboard
   keys typically displayed for them on a Mac (encode those symbols by
   using UTF-8 characters).

 - Drop " + " in between the keys, as that's not common on macOS for
   documenting keyboard shortcuts.

 - Convert lower case "g" to upper case "G", as that's common on macOS.

 - Add one additional space at start and end of key stroke set, to
   visually separate the key strokes from the rest of the text.

scripts/checkpatch.pl: Do not allow assert(0)

Since commit 262a69f428 ("osdep.h: Prohibit disabling assert()
in supported builds") we can not build QEMU with NDEBUG (or
G_DISABLE_ASSERT) defined, thus 'assert(0)' always aborts QEMU.

However some static analyzers / compilers doesn't notice NDEBUG
can't be defined and emit warnings if code is used after an
'assert(0)' call.

Apparently such compiler isn't as clever with G_DISABLE_ASSERT,
so we can silent these warnings by using g_assert_not_reached()
which is easier to read anyway.

In order to avoid these annoying warnings, add a checkpatch rule
to prohibit 'assert(0)'. Suggest using g_assert_not_reached()
instead. For example when reverting the previous patch we get:

  ERROR: use g_assert_not_reached() instead of assert(0)
  #21: FILE: target/ppc/dfp_helper.c:124:
  +            assert(0); /* cannot get here */

  ERROR: use g_assert_not_reached() instead of assert(0)
  #30: FILE: target/ppc/dfp_helper.c:141:
  +            assert(0); /* cannot get here */
