In order to allow easy debugging of some programs and runtimes, it is
often neccessary to add extra information in the timeline views. The
modification of the emulator to accomodate those temporal events is time
consuming and requires knowlegde of the emulator internals.
To improve the situation, a new set of functions are added to libovni
which allow users to define their own views. Up to 100 types of events
can be declared, where each type can have an unlimited number ov values
with an optional label attached.
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.
