weston: arm SEGV handler earlier

It is useful to print the backtrace regardless of whether we have a
compositor and a backend initialized yet. Move catch_signals() to the
earliest point in main() and protect the SEGV handler from dereferencing
NULL when we don't yet have a compositor or a backend.

The SEGV handler uses weston_log(), so cannot move catch_signals() any
earlier.

Calling wl_display_roundtrip() from within a Wayland event handler means
we will re-enter event dispatch, that is, it will lead to recursive
dispatch. Even if libwayland-client was safe, this would lead to
unexpected code paths: the first event handler function has not returned
when other event handler functions may get called. In this particular

Replace the wl_display_roundtrip() with a manual sync callback to do the
work.

This does not break the wayland-backend initialization sequence, because
sprawl_across_outputs was set only after the roundtrip to ensure
wl_registry globals have been received so the code would not have been
hit anyway, and weston_backend_init() also has a second roundtrip that
ensures the per wl_output events have been received before continuing.

For wayland-backend output hotplug the change is insignificant because
it will only delay the output creation a bit, and the parent outputs are
not processed anywhere in between.

Move the wl_output global management into weston_compositor_add_output()

If weston_output_enable() fails, there is no need to clean up the global
and the clients will not see a wl_output come and go.

Move the output id management into weston_compositor_add_output() and

works towards assimilating weston_output_enable_undo().

it was not used there to begin with.

libweston: prevent double weston_output_enable()

Enabling an already enabled output is an error, at least with the
current implementation.

However, disabling an output that has not been enabled is ok.

Cope with the first and document the second.

libweston: specify weston_output::enabled

It was ambiguous what this flag meant - it did not mean whether the
backend is considering this output to be enabled, because
weston_output_destroy() unsets it while deliberately not calling the
backend disable() vfunc.

Perhaps the most clear definition is with respect to the output's
assignment in the pending vs. enabled output lists. There is also a whole
bunch of variables that are allocated only when enabled is true.

Since the flag is related to the list membership, set and clear the flag
only when manipulating the lists.

Assert that weston_compositor_add_output() and
weston_compositor_remove_output() are not called in a wrong state.

libweston: move asserts to add_pending_output()

weston_compositor_add_pending_output() is the point through which all
backends must go when creating a new output. The enable and disable
vfuns are essential for anything to be done with the output, so it makes
sense to check them here, rather than when actually enabling or
disabling.

Particularly the disable vfunc is rarely called, so this gets the check
better excercised.
