v4l2-compliance: Fix build error clang TOT

We define the fallthrough keyword in compiler.h. but he c++ header files
uses as well that keyword and it get confused.

We could swap the order of the defines (like the other files in this
directory do). But this file does not use fallthrough, so we can remove
this define completely.

test_display.py: various fixes

- the top directory was /tmp/test_display/tmp/test_display, obviously
  wrong.
- check if the EDID file or /dev/i2c-X device exists and report if it
  doesn't.
- drop some unwanted newlines, ignore edid-decode exit error.
- require edid-compliance to also be run as root.

edid-decode: hide error when using -P and -a

When reading the EDID from the i2c device hide errors
if -P is also set. In that case just show f.f.f.f.

Do not hide if the EDID file does not exist, or if the
i2c device does not exist: those are too serious to hide.

test_display.py: fix cec-stress-sleep test

Tests for the cec-stress-sleep command were missing, so it didn't work
at all.

Added this.

Moved the test for root permissions to the top, before it tries to wake
up the display. That way you get informed immediately if it isn't run
with sudo.

If -a is used with cec-stress-sleep, and max-sleep is missing, then add
max-sleep=5.

test_display.py: add log options, checked with linter

Renamed to test_display.py ('-' in names is not recommended in
python), fixed a lot of pylint issues, add support to set the
top level log directory, or pass the log directory explicitly
(i.e. do not generate the log directory name). Also add an option
to skip creating the tar archive.

edid-decode: suppress two more errors if -P is used

Suppress two more errors when -P is used, i.e. when you want
to show the physical address. You just want to see f.f.f.f in that
case, otherwise it is hard to use in scripts.

test-display: add cec-ddc-reliability test

When testing HDMI cables it is nice to be able to test if there are
no glitches when reading EDID and transmitting CEC. This new test
allows you to do both and it verifies if the EDID and received CEC
messages are as expected.

cec-ctl/edid-decode: use seconds for the reliability test

The cec-ctl and edid-decode reliability tests both use 'count'
as a measure of how long these tests should take. But duration
in seconds is a much more useful number, especially since you
typically want to run both tests at the same time for the same
HDMI cable for the same duration.

So change the argument to be the number of seconds that the
test must run. '0' still means 'forever'.

test-display.py: test display CEC and EDID compliance

This contributes the test-display.py script that can be used to test
the CEC and EDID compliance of a display.

In particular the CEC stress tests are very helpful in testing the
display for race conditions that prevent it from going into Standby
or waking up.
