Change all backends to set the core backend pointer early.
This is necessary for libweston core to be able to access the backend
vfuncs before the backend init function returns. Particularly,
weston_output_init() will be needing to inspect the backend vfuncs to
see if the backend has been converted to a new API. Backends that create
outputs as part of their init would fail without setting the pointer
earlier.
For consistency, all backends are modified instead of just those that
could hit an issue.
Libweston core will take care of resetting the backend pointer to NULL
in case of error since "libweston: ensure backend is not loaded twice".

'release' is a more appropriate name because the function does not free
the underlying memory. The main reason for this is that we need the name
weston_output_destroy() for new API that actually will free also the
underlying memory.
Since the function is only used in backends and external backends are
not a thing, this does not cause libweston major version bump, even
though it does change the ABI. There is no way external users could have
successfully used this function.

Move the weston_output_init() call into wayland_output_create_common().
This avoids passing the name twice to different functions, and follows
the precedent set in "libweston: weston_output_init(..., +name)" for
calling init before accessing fields.
Since the error paths in wayland_output_create_for_parent_output() and
wayland_output_create_fullscreen() are now guaranteed to have
weston_output init'd, call weston_output_destroy() appropriately. There
might be more to free than just the name.

Add 'name' argument to weston_output_init(). This is much more obvious
than the assert inside weston_output_init() to ensure the caller has set
a field in weston_output first.
Now weston_output_init() will strdup() the name itself, which means we
can drop a whole bunch of strdup()s in the backends. This matches
weston_output_destroy() which was already calling free() on the name.
All backends are slightly reordered to call weston_output_init() before
accessing any fields of weston_output, except the Wayland backend which
would make it a little awkward to do it in this patch. Mind, that
weston_output_init() still does not reset the struct to zero - it is
presumed the caller has done it, since weston_output is embedded in the
backend output structs.

Initialize the list in weston_output_init() instead of doing it
separately in each backend.
One would expect weston_output_init() to initialize all weston_output
members, at least those that are not NULL.
We rely on the set_size() functions to be called only once, as is
assert()'d. If set_size() becomes callable multiple times, this patch
will force them to be fixed to properly manage the mode list instead of
losing all members.
compositor-wayland.c is strange in
wayland_output_create_for_parent_output(): it first called
wayland_output_set_size() that initialized the mode list with a single
mode manufactured from width and height and set that mode as current.
Then it continued to reset the mode list and adding the list of modes
from the parent output, leaving the current mode left to point to a mode
struct that is no longer in the mode list and with a broken 'link'
element. This patch changes things such that the manufactured mode is
left in the list, and the parent mode list is added. This is probably
not quite right either.

struct wayland_output::name was used but never initialized.
Also zxdg_toplevel_v6_set_title was only called for windowed outputs,
and some compositors let you see the client's name even when it is
fullscreen (GNOME Shell's Activities menu for example).
So rename struct wayland_output::name to struct wayland_output::title and
precompute it on wayland_output_create_common(), so it can be later used
on xdg's set_title and frame_create.
v2: Move zxdg_toplevel_v6_set_title() before the wl_surface_commit()

This is a complete port of the Wayland backend that
uses the recently added output handling API for output
configuration.
- Output can be configured at runtime by passing the
necessary configuration parameters, which can be
filled in manually, obtained from the configuration
file or obtained from the command line using
previously added functionality. It is required that
the scale and transform values are set using the
previously added functionality.
- Output can be created at runtime using the output
API. The output creation only creates a pending
output, which needs to be configured the same way as
mentioned above.
However, the backend can behave both as windowed backend
and as a backend that issues "hotplug" events, when
running under fullscreen shell or with --sprawl command
line option. The first case was covered by reusing
previously added functionality. The second case required
another API to be introduced and implemented into both
the backend and compositor for handling output setup.
After everything has been set, output needs to be
enabled manually using weston_output_enable().
v2:
- Fix wet_configure_windowed_output_from_config() usage.
- Call wayland_output_disable() explicitly from
wayland_output_destroy().
v3:
- Get rid of weston_wayland_output_api and rework output
creation and configuration in case wayland backend is
started with --sprawl or on fullscreen-shell.
- Remove unneeded free().
- Disallow calling wayland_output_configure more than once.
- Remove unneeded checks for output->name == NULL as that
has been disallowed.
- Use weston_compositor_add_pending_output().
v4:
- Drop unused fields from weston_wayland_backend_config
and bump WESTON_WAYLAND_BACKEND_CONFIG_VERSION to 2.
- Move output creation to backend itself when
--fullscreen is used.
- Prevent possible duplicated output names by assigning
a different name to outputs created without any
configuration specified.
