The CEC 2.0 specification explicitly forbids powering on a
display when Active Source is received. The older specification
does not explicitly forbid this (although it is really very clear
from the spec that you shouldn't do this).
Because the 1.4 spec was not crystal clear some devices expect a
display to power up when receiving Active Source, and so some
displays actually support this, thus failing this test.
So for 1.4 displays this test will report a warning, but it will
fail for 2.0 displays.

Check if the remote CEC device can handle the CEC core messages when
in standby. And check that what is returned is equal to the value
returned when the device was on.

Some devices will ignore a STANDBY command after an IMAGE/TEXT_VIEW_ON
if it is received on an input that is not the current input.
So transmit an ACTIVE_SOURCE after the display wakes up following an
IMAGE/TEXT_VIEW_ON.

A STANDBY was sent right after the display reports it was powered on,
but that standby was ignored and had to be re-transmitted.
Warn if that happens.

Add new tests that check if a TV wakes up when Image or Text View On
is sent.
Also fix several related bugs in the code that waits for power
status transitions, esp. when dealing with TVs that pull the HPD
low when in standby.

This shouldn't be CEC 2.0 specific, it is also valid for 1.4.

time() returns time_t, whose definition is arch-dependent.
This fixes the following warnings:
cec-test-power.cpp: In function ‘bool wait_changing_power_status(node*, unsigned int, unsigned int, __u8&, unsigned int&)’:
cec-test-power.cpp:273:24: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
while (time(NULL) - t < long_timeout) {

The initiator for Image View On should be 0xf (Unregistered) if there
is no HPD, or the adapter's logical address if there is a valid HPD.

The standby tests failed for TVs that disable the HPD when in
standby. One reason was a silly mistake in a condition testing
for CEC_CAP_NEEDS_HPD: a ! was missing there.
But other issues were related to the tests themselves (don't
issue an IMAGE_VIEW_ON when trying to transmit a GIVE_POWER_STATUS,
STANDBY or ACTIVE_SOURCE command since that would defeat the purpose).
Another issue that the long_timeout handling was wrong. Use time()
to determine if we timed out, that's much more reliable compared to
the old method.
Tested with a display with this 'feature'.

The test didn't first send an 'Active Source' message to ensure that it
became the Active Source. This was done when in interactive mode, but
in non-interactive mode this never happened.

The default timeout for power-related messages is 60 seconds. Add the --timeout
option to make this configurable.

If during power transitions the CEC adapter becomes unresponsive,
then warn about that instead of failing.

Once failure message looked odd due to a missing newline at the end

This improves the One Touch Play tests to make them more in line with
the HDMI 1.4b Compliance Test Specification. Probing for Image View On
and Text View On is separated out and always performed, and in
interactive mode, there are now separate tests for waking up upon
receiving Image/Text View On, and changing to the correct input when
receiving Image/Text View On (followed by Active Source)

This utility makes it possible to test the local CEC adapter and/or a remote
CEC device. It verifies as much as possible whether the CEC implementation
follows the CEC specification.
Note that these CEC features have currently limited test coverage:
One Touch Record
Deck Control
Device Menu Control
Audio Rate Control
Tuner Control
Timer Programming
Capability Discovery and Control
Vendor Specific Commands
There is also no or very limited testing for Unregistered devices,
CEC switches and CDC-only devices.
Many thanks to Johan Fjeldtvedt who did this work during his Cisco Summer
internship!
