Rename fbdev_frame_buffer_destroy() to fbdev_frame_buffer_unmap()
because that is what it does. Adding the destruction of hw_surface in it
makes it the perfect counterpart to fbdev_frame_buffer_map() which
simplifies the code.
fbdev_frame_buffer_map() can no longer call that, so just open-code the
munmap() there. It is an error path, we don't really care about
failures in an error path.
The error path of fbdev_output_enable() is converted to call
buffer_unmap() since that is exactly what it did.
fbdev_output_disable() became redundant, being identical to
fbdev_frame_buffer_unmap().
Invariant: output->hw_surface cannot be non-NULL without output->fb
being non-NULL. hw_surface wraps the mmapped memory so cannot exist
without the mmap.

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

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.

[Pekka: rebased]
EGL code was added to the fbdev backend in
4aa756dc7a in 2013, apparently for running
Weston on libhybris with Android hardware drivers.
This actually had nothing to do with the fbdev backend, really. Fbdev
was just a convenient platform to plug in the EGL init code and load
GL-renderer. Fbdev itself was not used at all in this case.
Fbdev should be forgotten and die, as we have better interfaces for
accelerated rendering and for controlling displays. It may be a bit too
harsh to remove the whole fbdev backend just yet, but let us at least
simplify it this much.
Fbdev+EGL has been the unholy union used by proprietary driver stacks of
hardware vendors in the non-PC world as a quick and dirty way to get
something out on the screen. In these cases it is actually the EGL
implementation that does everything internally, fbdev is not needed.
Fbdev was never meant for the sort anyway.
If anyone still needs this use case, I recommend sticking with a
outdated Weston to match your outdated platform. Or if you really
insist, write a new backend that does not pretend to use fbdev and just
initializes EGL and GL-renderer.

Normally we need to check if a seat's [device_type]_count is > 0 before
we can use the associated pointer. However, in a binding you're
guaranteed that the seat has a device of that type. If we pass in
that type instead of the seat, it's obvious we don't have to test it.
The bindings can still get the seat pointer via whatever->seat if they
need it.
This is preparation for a follow up patch that prevents direct access

This caused problems when creating a new view in a listener to that signal,
because weston_view_assign_output() doesn't yet know the new output exists.
To fix this add a new weston_composito_add_output() func which adds the
output in the list and later sends the signal, and make the backends call
that.
This means compositors don't need to call supports() manually and
create() will just return -1 in the failure case as before. This also
