Fix pthread_create warning on translator termination
This was due to task_terminate not actually properly suspending threads
before disable the task port, which was thus preventing pthread_create
from being able to create a stack. Thanks Gabriele Giacone for finding
out a reproducer of this.
* kern/task.h (task_hold_locked): New declaration.
* kern/task.c (task_hold): Move the locked part of the code into...
(task_hold_locked): ... new function.
(task_terminate): Call task_hold_locked just before deactivating the
task. Call ipc_task_disable after waiting for threads to actually
suspend with task_dowait.
