MEDIUM: task: Split the tasklet list into two lists.

As using an mt_list for the tasklet list is costly, instead use a regular list,
but add an mt_list for tasklet woken up by other threads, to be run on the
current thread. At the beginning of process_runnable_tasks(), we just take
the new list, and merge it into the task_list.
This should give us performances comparable to before we started using a
mt_list, but allow us to use tasklet_wakeup() from other threads.
