[igt PATCH 0/4] add support for testing clone output configs

[Imre Deak <imre.deak@intel.com>]

Based on irc discussions with Chris/Daniel we needed a new test case
that iterates through all clone output configurations, so this patchset
adds one.

I tested it on ilk, ivb, hsw. One case triggered a DP link training error
on ilk. Got some HW state readout/check WARNS on others. On my hsw
desktop some hdmi+dp configurations fail, although they seem to be
valid. Also here enabling hdmi sometimes ends up outputting something on
the dp connector, so perhaps it's some sort of hdmi vs. dp physical port
sharing that Ville told me about, but I haven't figured yet out the
exact reason for any of these.

Note that this will take a while to run especially if you have 3
displays connected...

Imre Deak (4):
  lib: shorten DP/eDP connector names
  lib: handle SIGSEGV similarly to other error signals
  lib: add subtest extra command line option handling
  tests: add kms_setmode
