Keep the thread set after the task ends
...
Allows the emulator to check when an inner task ends the next in the
stack has the same thread as before.

Add an stronger restriction for task switching
...
In nOS-V, we can only switch from a running task to another if they are
from the same thread.

This avoids different processes running tasks with the same type label
to have different colors.

Add support for nOS-V task types

same id per-process.

Use only a stack of tasks for nosv
...
The running task is inferred from the task on top of the stack. Also,
allow a nested task to execute when there are others in the stack.

A priority queue (in heap.h) is used to keep the next event ready in the
emulator loop. Additionally, a list of dirty channels is keept to
limit the complexity of the propagation and emit phases.
