This way we can report issues from a scenario
Also add a Seek aread to the known areas list
We now need to pass the runner to the scenario instead of the
pipeline as the GstQaReporter interface needs it.
Various type of object should be able to do some reporting, so we have
to make sure all the code to do that is in one place. Creating an interface
makes it simple to share information and it avoid to have a baseclass for
something that is not actually important enough to create a baseclass.

gst/qa/gst-qa-pad-monitor.c
Remove error from GstQaErrorReport, making it only GstQaReport. Add
a level and use area and subarea code, with an extra string for message
adding details.
Provide macros on qa-monitor to make it easy to create reports.
