This stores the autoresume delay provided via igt_set_autoresume_delay
for use during suspend via rtc wake scheduling. This delay was
previously only used for pm_test suspendm while the function suggests
it should be applied to all autoresume cases.
There is also definitely a use case for configuring the rtc wake delay,
so this implements it.

This adds support for the newly-introduced ScheduleHpdToggle XMLRPC
method of the Chamelium's interface and makes use of it instead of
starting pulses with an asynchronous call, suspending and dealing with
the result at resume.
The XMLRPC library does not guarantee that the call will be made before
caring for its outcome and this is in fact what was happening:
the call was being delayed until resume time, as can be seen from the
Chamelium's logs. The quite generous timeout for HPD event detection
would then catch the toggle, that was sent after resume.
This is especially useful for testing HPD during suspend/resume.

This adds HPD toggle after suspend and hibernate testing for VGA, in the
same fashion as currently done for DP and HDMI and includes VGA in the
common suspend and hibernate test.

Since VGA hpd detection is done through RGB lines load detection and
nowadays often goes through a bridge to some digital interface, HPD
detection usually takes a while (up to a couple seconds).
Thus, it is not as relevant to stress it as many as 15 times.
This brings the toggle count down to 5 times, which makes the test run
a lot faster without really changing the outcome much.

This renames the reprobe_connector function to update_connector and
ensures that full reprobe of the connector is only done when really
necessary (e.g. when changing the EDID).
A full reprobe takes time and is not required for updating the connector
state. Thus, this allows executing tests faster.

This removes the reset call from the reset_state function and renames it
to disconnect_connector. Since a call to reset is already done in
chamelium_init, there is no need to do an extra reset in each test.
This allows reducing the execution time a bit.

This adds support for configurable suspend/resume delay and takes the
occasion to move igtrc configuation from igt_chamelium to igt_core.
This way, suspend/resume delay configuration can be used for all tests.

We should probably at least throw an error if the key value happens to
be there, but the value is invalid (such as someone specifying "foo" as
the SuspendResumeDelay value). Maybe add a function like
static int
igt_config_get_integer(const char *section, const char *key_name, int *value, int default)
That calls the appropriate glib functions, and fails the current test
if any invalid non-default values are given

NAK, I'd rather just go with the idea you had with removing the
connector reset in chamelium_init()

Martin was really expecting this to come around, so I hope it is in accordance
with the DRM spec. At least, it works properly with i915 on SKL.
Thanks for double-checking!

Okay then, I'll craft v3 in that directon. This is not a big overhead anyways,
and it does not change anything when running subtests separately (which is what
most test infrastructures using igt seem to be doing).
