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.

Use a hash of the type label to derive the gid
...
This avoids different processes running tasks with the same type label
to have different colors.

Add support for nOS-V task types
...
Use a unique identifier for each type, so we don't mix types with the
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.

file descriptors opened when loading large traces.

Add kernel support for context switch events
...
These events only show if a thread has been removed from the CPU, but
doesn't provide information about what other thread caused the context
switch. This type of information can be obtained even with strict
/proc/sys/kernel/perf_event_paranoid settings.

different state are allowed now.

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.
