logind: rework display counting when detecting whether the system is docked
Previously, we'd just count connected displays, and if there was 2 or
more we assumed a "docked" state.
With this change we now:
- Only count external displays, ignore internal ones (which we detect by
checking the connector name against a whitelist of known external plug
types)
- We ignore connectors which are explicitly disabled
- We then compare the count with >= 1 rather than >= 2 as before
This new logic has the benefit that systems that disconnect the internal
display when the lid is closed are better supported. Also, explicitly
disabled ports do not confuse the algorithm anymore.
This new algorithm has been suggested here:
http://lists.freedesktop.org/archives/intel-gfx/2015-June/068821.html
This also makes two functions static, that are not used outside of their
.c files.
