Christopher Faulet 3911ee85df MINOR: tasks: Use a bitfield to track tasks activity per-thread
a bitfield has been added to know if there are runnable tasks for a thread. When
a task is woken up, the bits corresponding to its thread_mask are set. When all
tasks for a thread have been evaluated without any wakeup, the thread is removed
from active ones by unsetting its tid_bit from the bitfield.
