Chameleon: Implement a stress test to switch EDID from among a large pool
This test switches Chameleon EDID from among a large pool of EDIDs, tests
DUT recognizes the emulated monitor and emits the correct video signal to
Chameleon.
The first batch of EDIDs come from the monitors in use by the QA team and
the previous reported bugs.
Add the support of importing text format (xrandr output) in the EDID library.
