[Intel-gfx] [PATCH i-g-t 1/3] lib/kms: Let display commits wait for keypress while debugging

[Matt Roper]

Add a call to igt_debug_wait_for_keypress() immediately before we commit
new hardware state to help simplify display debugging.

To use this, just set the environment variable:

        IGT_DEBUG_INTERACTIVE=commit
