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.

The check_clock_gate() was trying to access to the first event in all
streams. However, streams that are empty don't have any event, so they
cause a NULL dereference. Skipping not active streams avoids the
problem.
Generates a script with the values of the delta clock, PRV type and
value to be matched in the .prv traces, to ensure the emulator emitted
the switching type event.
Ensures that the select callback will be called on the propagation
phase, immediately setting the right output. Otherwise the mux won't be
updated until the select channel sets a new value.
Adds ovni_version_check() to test the version at runtime, set the
SONAME to the major version and install a symlinks to the complete
version:
libovni.so -> libovni.so.1
libovni.so.1 -> libovni.so.1.0.0
libovni.so.1.0.0
