Enabled is orthogonal from connected. A connected head could be

Compositors quite likely want to check if a head is already enabled
before starting to take it into use.

Heads may be disconnected or connected and the compositor needs to be
able to know the state to know which heads to take into use.
Currently a single head is automatically created with an output, and
outputs are only ever created as connected and destroyed on
disconnection, so it suffices to set connected to true. In the future,
backends are expected to create heads for both connected and
disconnected connectors, so that a connector can be forced on without it
being actually connected.

The 'head' member of 'struct weston_output' is going to go unused and
then disappear, so stop using it and find a head from the proper list.
However, this leaves a problem in cms-colord: if you have multiple
monitors driver with the same CRTC, what do you say to the color
management system? The monitors could be different, but all the color
LUTs etc. are in the CRTC and are shared, as is the framebuffer.
Do the simple hack here and just use whatever head happens to be the
first in the list.
The warning is printed in get_output_id(), because if heads are added or
removed while the output is enabled, the id could change.

Remove the wl_resource in the head's resource list when we are
removing the wl_output global. We sent global removal events to clients,
the resources should become dummies until clients reap them. Reset user
data so that clients triying to use dummy objects don't hit e.g. a freed
head pointer.
This fixes a theoretical issue: if an enabled output is disabled and
then gets enabled again, mode changes and wl_surface.enter/leave would
still attempt to use the dummy objects. If a client destroyed a dummy
object, we don't have the destructor to remove it from the resource
list, and libweston would hit freed memory.

The intention is that in the future backends will dynamically allocate
weston_heads based on the resources they have. The lifetime of a
weston_head will be independent of the lifetime of a weston_output it
may be attached to. Backends allocate objects derived from weston_head,
like they currently do for weston_output. Backend will choose when to
destroy a weston_head.
For clone mode, struct weston_output gains head_list member, which is
the list of attached heads that will all show the same framebuffer.
Since heads are growing out of weston_output, management functions are
added.
Detaching a head from an enabled output is allowed to accommodate
disappearing heads. Attaching a head to an enabled output is disallowed
because it may need hardware reconfiguration and testing, and so
requires a weston_output_enable() call.
As a temporary measure, we have one weston_head embedded in
weston_output, so that backends can be migrated individually to the new
allocation scheme.

The user data of a wl_resource representing a wl_output protocol object
used to be a pointer to weston_output. Now that weston_output is being

monitor.
Change the wl_output user data to point to weston_head.
weston_output_from_resource() is replaced with
weston_head_from_resource().
This change is not strictly necessary, but architecturally it is the

The wl_output protocol interface exposes things like monitor make,
model, sub-pixel layout and physical dimensions. Obviously wl_output is
meant to represent a monitor.
The abstraction of a monitor is weston_head. Therefore move the wl_output
global and the bound resources list into weston_head.
When clone mode gets implemented in the future, this means that monitors
driven by the same CRTC will still be represented as separate wl_output
globals. This allows to accurately represent the hardware.
Clone mode that used separate, not frame-locked, CRTCs to drive two
monitors as clones would necessarily also be exposed as separate
wl_output since they have different timings.

In order to support clone modes, libweston needs the concept of a head
that is separate from weston_output. While weston_output manages buffers
and the repaint state machine, weston_head will represent a single
monitor. In the future it will be possible to have a single
weston_output drive one or more weston_heads for a clone mode that
shares the framebuffers between all cloned heads.
All the fields that are obviously properties of the monitor are moved
from weston_output into weston_head.
As moving the fields requires one to touch all the backends for all the
assingments, introduce setter functions for them while we are here. The
setters are identical to the old assignments, for now.
As a temporary measure, weston_output embeds a single head. Also the
ugly casts in weston_head_set_monitor_strings() will be removed by a
follow-up patch.

As keyboard_focus_resource_destroyed() sets the focus to NULL, this

always have a wl_resource.
I have confirmed the added branch in weston_keyboard_set_focus() can be
