[PATCH weston v3 05/36] libweston: make wl_output point to weston_head

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

The user data of a wl_resource representing a wl_output protocol object
used to be a pointer to weston_output. Now that weston_output is being
split, wl_output more accurately refers to weston_head which is a single
monitor.

Change the wl_output user data to point to weston_head.
weston_output_from_resource() is replaced with
weston_head_from_resource().

This change is not strictly necessary, but architecturally it is the
right thing to do. In the future there might appear the need to refer to
a specific head of a cloned pair, for instance.
