c40348e2a8 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.

b0f693360c 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.

fa9196fd63 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.

70891355ec 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.

ca9bbf6401 Close file descriptors after mmap
Now is no longer needed to increase the limit of the maximum number of
file descriptors opened when loading large traces.

ca95fb34a3 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.

5a940540d3 Use priority queue for streams and fast channels
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.
