The nOS-V events are modified in two ways: 1) to create a parallel task
the new VTC event must be used and 2) all task events for both normal
(VTc) and parallel (VTC) tasks require an extra argument in the payload
to indicate the body id. As a consequence, the nOS-V model version is
now increased to 2.0.0.
Additionally, all the channel PRV flags are set to PRV_SKIPDUPNULL, so
duplicates are only emitted if they are not null. It solves the problem
when a task switches to another task with the same body id.
A new Paraver configuration is added for the body id.
In nOS-V, when a task was paused via the VTp event, two things were
happening: 1) the task state was set to pause and 2) the subsystem state
"Task: Running" was being popped.
This causes a problem when a task calls nosv_submit() in blocking mode,
as it will call nosv_pause() which will emit a VTp event from a
subsystem different than "Task: Running".
To solve this conflict, we handle the subsystems state and the task
state separately with the VTp and VTr events. The subsystem state "Task:
Running" no longer is connected to the state of the task and only shows
if we entered the body of the task or not. It has now been renamed to
"Task: In body".
The new state "Task: In body" represents that the task body has begun
the execution and is still in the stack, but the task may be paused. The
subsystem is not changed by the VTp (pause) or VTr (resume) events.
