Between assign_planes() and pnode_update_late(), the pnode's plane may
not yet be up to date. This leads to the visible region being incorrectly
calculated for paint nodes beneath a paint node that changes planes. Their
visible regions will still contain a cut out for the node that no longer
occludes them.
However, we place damage on nodes beneath a node that changes planes in
order to redraw the region beneath a node that moves from the primary to
non-primary plane.
The gl-renderer clips to a paint node's visible region when rendering it,
so this accidental cut-out masks away all the damage and leaves us with
a mess.
Fix this by using the correct plane in the visibility calculation.

Second try at removing direct logind support. This time more careful

This reverts commit 55bf6b5046.
This accidentally removed things that should have stayed - libseat
can still use the logind API, even if weston doesn't directly use
it.
Note that the logind-launcher does not actually build anymore
because breaking changes landed before this revert.
Since we're removing it again right away, I've not taken care to
fix that.

Releasing the buffer reference here works because the backend has seen the
surface and has updated keep_buffer if necessary. With multiple backends
the assumption breaks. The same surface may be visible (now or later) on an
output from another backend. This backend has not seen the buffer yet so it
cannot update keep_buffer.
As a result, the reference is released to early. A surface that is rendered
on a secondary backend first can no longer be placed on a plane on a DRM
backend.
To avoid this, always keep the buffer reference until it is replaced when
multiple backends are involved.

Before loading a backend, clear the weston_compositor::backend pointer
to check whether the backend supports multi-backend operation and adds
itself to the weston_compositor::backend_list.
Keep weston_compositor::backend pointing to the last loaded backend
either way, to allow the calling compositor code to store it away for
later, to check whether a head belongs to a given backend in the output
configuration code. This workaround can be removed after all backends
are converted to be multi-backend aware.
