commit e7fff215ad made initializing the
selection_listener conditional, but didn't make its clean-up
conditional at shutdown. Simply initializing the listener's list
link at init time makes this harmless.
To see this, run weston -Bheadless-backend.so and then connect to it
with an X client. When killing weston it will attempt shutdown but
die with a segfault.

Starting an xterm with no input device led to a crash
because weston_wm_pick_seat() was returning garbage and
weston_wm_selection_init() was trying to use the garbage.

weston maintains a copy of the most recently selected "thing" - it picks
the first available type when it copies, and saves that one only.
When an application quits weston will make the saved selection active.
When xwm sees the selection set it will check if any of the offered types
are text. If no text type is offered it will clear the selection.
weston then interprets this in the same way as an application exiting and
causing the selection to be unset, and we get caught in a live lock with
both weston and xwayland consuming as much cpu as they can.
The simple fix is to just remove the test for text presence.

The wrapped weston_data_source struct has new fields which were left
uninitialized, so its access is unreliable.
The data source in xwayland/dnd.c should be eventually setting the
drag-and-drop actions, but it is a lot more incomplete than that
(read: completely), so falls out of the scope of this patch.

This reverts commit d3553c721c.
weston_wm_write_property() takes the ownership of the reply it gets as
a parameter, and will eventually free it later in writable_callback.
This change introduced a double-free when Xwayland programs triggered a
copy to the clipboard, leading to a Weston crash.

dump_property allows reply to be NULL. Calling it unconditionally will
ensure user knows where the selection failed.
Also refactor code a bit.
