f461414501 libweston: remove restore functionality
This was used from the crash handlers, which do not exist anymore.
Nothing calls restore, so delete the dead code.

7da9a3802f libweston: set backend pointer earlier
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".

ae6d35db14 libweston: rename weston_output_destroy() to weston_output_release()
'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.

26ac2e1218 libweston: weston_output_init(..., +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.

4270414549 libweston: move weston_output::mode_list init to core
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.

7fb17756fc weston: Port headless backend to new output handling API
This is a complete port of the headless 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.

After everything has been set, output needs to be
enabled manually using weston_output_enable().

Same as before, a single output is created at runtime
using the default configuration or a configuration
parsed from the command line. The no-outputs
functionality is also preserved, which means that no
output will be created initially, but more outputs can
be added at runtime using the output API.

New feature:

This patch also adds, as a bonus of using shared
functionality, support for setting options for outputs
created by this backend in the weston config file in
addition to setting them from the command line.

v2:

 - Fix wet_configure_windowed_output_from_config() usage.
 - Call headless_output_disable() explicitly from
   headless_output_destroy().

v3:

 - Add scale support to output width and height.
 - Use scaled values in calls to various functions which
   require width and height.
 - Disallow calling headless_output_configure more than once.
 - Remove unneeded checks for output->name == NULL as that
   has been disallowed.
 - Use weston_compositor_add_pending_output().
 - Bump weston_headless_backend_config version to 2.

d84deeb173 compositor-headless: Support starting with zero outputs
This patch adds a new command line option which can be
used to tell headless backend not to create any
virtual outputs.

This will be used for output hotplug emulation, where
weston will start with no outputs available, and the
virtual output will be created at runtime.

v2:

- Use bool instead of int for the indicator flag
- Move final newspace to a separate line in command
  line options
