[PATCH i-g-t 0/8] Refactors and fixes for drm_clients

[Lucas De Marchi]

Some refactors and fixes I did while adding support for
gputop in xe. I will send those later on top, but I think
these can already be reviewed.

Last patch should NOT be applied for now. In my mind the lazy approach
makes total sense and should be faster. But reality doesn't agree with
me and after timing igt_drm_clients_scan() it shows a ~10% slow down.
Hard to explain. Maybe I didn't have enough coffee when benchmarking it. 

I don't like much the strstartswith() with and extra output param.
Maybe changing its name to something else would make it better.
