When we create a new view, assign it to the primary plane from the
beginning.
Currently, every view across the compositor will be assigned to a plane
during every repaint cycle of every output: the DRM renderer's
assign_planes hook will either move a view to a drm_plane, or to the
primary plane if a suitable drm_plane could not be found for the output
it is on. There are no other assign_planes implementation, and the
fallback when none is provided, is to assign every view to the primary
plane.
DRM's behaviour is undesirable in multi-output situations, since it
means that views which were on a plane on one output will be demoted to
the primary plane; doing this causes damage, which will cause a spurious
repaint for the output. This spurious repaint will have no effect on the
other output, but it will do the same demotion of views to the primary
plane, which will again provoke a repaint on the other output.
With a simple fix for this behaviour (i.e. not moving views which are
only visible on other outputs), the following behaviour is observed:
- outputs A and B are present
- views A and B are created for those outputs respectively, with SHM
buffers attached; view->plane == NULL for both
- current buffer content for views A and B are uploaded to the
renderer
- output A runs its repaint cycle, and sets keep_buffer to false on
surface B's output, as it can never be promoted to a plane; it does
not move view B to another plane
- output B runs its repaint cycle, and moves view B to the primary
plane
- weston_view_assign_to_plane has work to do (as the plane is changing
from NULL to the primary plane), calls weston_surface_damage and
calls weston_surface_damage
- weston_surface_damage re-uploads buffer content, possibly from
nowhere at all; e508ce6a notes that this behaviour is broken
Assigning views to the primary plane when created makes it possible to
fix the DRM assign_planes implementation: assign_planes will always set
keep_buffer to true if there is any chance the buffer can ever be
promoted to a plane, regardless of view configruation. If the buffer
cannot be promoted to a plane, it must by definition never migrate from
the primary plane. This means that there is no opportunity to hit the
same issue, where the buffer content has already been discarded, but
weston_view_assign_to_plane is not a no-op.

Forcing DPMS on when we lose our session may force an expensive modeset
operation, which is pointless if the next consumer (another compositor,
or the console) is going to do a modeset. These should force DPMS on
regardless.
This actively causes problems for the DRM backend, in that it may
actually require a repaint to set coherent state for DPMS off -> DPMS on
transitions, which is very much not what we want when going offscreen.
As DRM is the only backend which actually implements DPMS, just remove
this call.

This always changes the state to ACTIVE when we enter the session,
whereas the previous implementation preserved the state (i.e. if state
was SLEEPING on exit, it would be restored to SLEEPING, but also with a
repaint). This seems more helpful behaviour, however: if you enter a
session, it's probably in order to interact with it.

The xwayland window type XWAYLAND is not handled by the shell at all,
instead libweston-desktop maps such surfaces itself. However, it forgot
to set weston_surface::is_mapped and weston_view::is_mapped.
weston_surface::is_mapped affects the behaviour of weston_view_unmap()
and weston_surface_attach().
weston_view::is_mapped affects the behaviour of weston_view_unmap() and
weston_view_destroy().
When manually mapping a window of type XWAYLAND, mark both the view and
surface as mapped. This follows the expections in libweston, even though
the meaning of is_mapped is not clearly defined for either surface or
view.
Also, when the XWAYLAND window is manually unmapped, unmap the
weston_surface. This updates weston_surface::is_mapped to reflect the
state. However, as a side-effect it will also unmap all sibling views,
should any exist.
