wayland_common: implement output tracking, cleanups and bugfixes

This commit:
    - Implements output tracking (e.g. monitor plug/unplug)
    - Creates the surface during registry (no other dependencies)
    - Queues the callback immediately after surface creation
    - Cleaner and better event handling (functions return directly)
    - Better reconfigure handling (resizes reduced to 1 during init)
    - Don't unnecessarily resize  (if dimensions match)

Apart from that fixes 2 potential memory leaks (mime type and window
title), 2 string ownership issues (output name and make need to be
dup'd), fixes some style issues (switches were indented) and finally
adds messages when disabling/enabling idle inhibition.

The callback setter function was removed in preparation for the commit
which will use the frame event cb because it was unnecessary.
