From: Thierry Reding <treding@xxxxxxxxxx>
Allow connector names to be used in the specification of the -s option.
This requires storing the string passed on the command-line so that it
can later be resolved to a connector ID (after the DRM device has been
opened).
Connector names are constructed from the connector type name and
connector type ID using the same format as used internally in the
Linux kernel.

I've carried this patch in my tree for too long and I'm now tired of rebasing
it. It's thus time to get it in mainline.
Compared to the original version developed by Thierry, I've
- rebased the patch on top of latest master
- dropped dependencies on other WIP patches in Thierry's tree
- fixed printf alignment
- used asprintf to simplify name string allocation
- constructed the connector name using the same format as the Linux kernel
