The wp_linux_drm_syncobj_v1 protocol states that :
| If at surface commit time there is a pending buffer attached but no
| pending release timeline point set, the no_release_point protocol
| error is raised.
So we need to set a release timeline point in any case from the swap
pixmap routine, even for the early out code paths.
Failing to do so may cause a Wayland protocol error that is fatal to the
Wayland client, in this case Xwayland:
| wp_linux_drm_syncobj_surface_v1: error 4: No Acquire point provided
| (EE) failed to dispatch Wayland events: Protocol error
Closes: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1688
Fixes: 87bf2cafcc - xwayland: add support for wp_linux_drm_syncobj_v1

Move the code which takes care of submitting pixmaps and the
synchronization points to its own function.
This will allow to reuse that code from different code path.

The function xwl_window_swap_pixmap() can be called from two places,
either from xwl_window_attach_buffer() or from damage_report().
When called from xwl_window_attach_buffer(), the new buffer is attached
and the surface committed.
However, when called from damage_report(), a new buffer might not be
attached before the surface is committed.
That's fine with implicit synchronization, but if we use explicit
synchronization, committing a surface without a new buffer attached but
with a release timeline point set is a protocol error:
| If at surface commit time there is a pending release timeline point
| set but no pending buffer attached, a no_buffer error is raised.
To avoid such an issue, add a new parameter to xwl_window_swap_pixmap()
to hint whether it should set the synchronization points, and have the
synchronization points set only from xwl_window_attach_buffer().

Copy the code to deal with synchronization objects from the window
buffers to the GLAMOR/GBM code.
The idea is to deal with synchronizations for all pixmaps, even when
there is no window buffer involved.
This is still preparation work for the following commits, no functional
change intended at this point.
v2: Use a "xwl_window_buffer *" instead of a "void *data" (Michel)
v3: Bail early if there's no xwl_window_buffer (Michel)

We want to decorrelate the explicit buffer synchronization from the
window buffers, and move that to the GLAMOR/GBM code instead.
To do that, we need to be able to invoke the xwl_window_buffer's
release_callback() routine from outside the window buffer code.
For that purpose, introduce xwl_window_buffer_release() which calls
xwl_window_buffer_release_callback() for us.
This is preparation work for the following changes, no functional change
intended at this point.

This fixes a hang on simpledrm where min_cursor_height and min_cursor_width is
never established, and drmmode_load_cursor_argb_check would infinitely when
the minimum values where 0 or less.
If the surface window already uses automatic redirection, we can upgrade
to manual redirection and save some blits with common use cases.
This fixes a minor performance regression from a65bb8480a ('Revert
"xwayland/glamor: Avoid implicit redirection with depth 32 parent
windows"') with mutter >= 44.

If the manual redirection was done by xwl_present_maybe_redirect_window,
we are in control.
This allows xwl_present_maybe_redirect_window to work as intended again.
Previously, xwl_window_update_surface_window would ignore the window
redirected by xwl_present_maybe_redirect_window, which would result in
xwl_present_maybe_redirect_window undoing the redirection and bailing.

This could potentially be security related or crash the server:
XFixesSelectSelectionInput() calls the XACE_SELECTION_ACCESS hook with
wrong parameter type: XID instead of pointer to Selection struct.
It seems that it hadn't been kept up in XACE changed to polyinstantiation.
When XACE is used (eg. Security or SELinux extension enabled), this can
easily lead to memory corruptions at attacker-controlled locations, since
the client-given XID is interpreted as the memory location of Selection
structure.

DES isn't considered secure anymore for long time now, more and more platforms
dropping DES from their RPC implementations, and even the one where it came
from (Solaris) disabled it for a decade now. We have much better alternatives
(eg. passing creds via Unix socket for local connections, ssh tunneling,
MIT-MAGIC-COOKIE-1, ...), so it's unlikely anybody still really relying on it.
Therefore, sweep it out.
