Thibault Saunier 4992249848 qa: Add a GstQaReporter interface that objects needing reporting can implement 
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.

/*
* Locking the parent should always be done before locking the
* pad-monitor to prevent deadlocks in case another monitor from
* another pad on the same element starts an operation that also
* requires locking itself and some other monitors from internally
* linked pads.
*
* An example:
* An element has a sink and a src pad. Some test starts running at sinkpad
* and it locks the parent, and then it locks itself. In case it needs to get
* some information from the srcpad, it is able to lock the srcpad and get it
* because the srcpad should never lock itself before locking the parent (which
* it won't be able as sinkpad already locked it).
*
* As a side one, it is possible that srcpad locks itself without locking the
* parent in case it wants to do a check that won't need to use other internally
* linked pads (sinkpad). But in this case it might lock and unlock freely without
* causing deadlocks.
