For now, only one listener can receive GL events. Let's dispatch to all
listeners. (preliminary check ensure there is a single listener now
during regitration, and in next patches, compatible listeners only)

GraphicHw.gl_flushed was introduced to notify the
device (vhost-user-gpu) that the GL resources (the display scanout) are
no longer needed.
It was decoupled from QEMU own gl-blocking mechanism, but that
difference isn't helping. Instead, we can reuse QEMU gl-blocking and
notify virtio_gpu_gl_flushed() when unblocking (to unlock
vhost-user-gpu).
An extra block/unblock is added arount dpy_gl_update() so existing
backends that don't block will have the flush event handled. It will
also help when there are no backends associated.

vnc_server_cut_text_caps() is not guaranteed to be called only once.
If it called twice, we finally call notifier_list_add() twice with same
element. Which leads to loopback QLIST. So, on next
notifier_list_notify() we'll loop forever and QEMU stuck.
So, let's only register new notifier if it's not yet registered.
Note, that similar check is used in vdagent_chr_recv_caps() (before
call qemu_clipboard_peer_register()), and also before
qemu_clipboard_peer_unregister() call in vdagent_disconnect() and in
vnc_disconnect_finish().

The dmabuf often becomes invalid right after unblocking pipeline
and graphic_hw_gl_flushed in case a new scanout blob is submitted
because the dmabuf associated with the current guest scanout is
freed after swapping.
So both graphic_hw_gl_block and graphic_hw_gl_flushed should be
executed after closing fence_fd for the current dmabuf.

MacOS provides header files for curses 5.7 with support
for wide characters, but requires _XOPEN_SOURCE_EXTENDED=1
to activate that.
By default those old header files are used even if there
is a newer Homebrew installation of ncurses 6.2 available.
Change also the old macro definition of NCURSES_WIDECHAR
and set it to 1 like it is done in newer versions of
curses.h when _XOPEN_SOURCE_EXTENDED=1 is defined.
OpenBSD has the same version of ncurses and needs the same fix.

This is a bugfix that stretches all the way back to January 2020,
where I initially introduced this problem and potential solutions.
A quick recap of the issue: QEMU did not sync up with the monitors
refresh rate causing the VM to render frames that were NOT displayed
to the user. That "fix" allowed QEMU to obtain the screen refreshrate
information from the system using GDK API's and was for GTK only.
Well, I'm back with the same issue again. But this time on Wayland.
And I did NOT realize there was YET another screen refresh rate
function, this time for Wayland specifically. Thankfully the fix was
simple and without much hassle.
Thanks,
Nikola
