Support task_wait / task_wait_tid syscalls:
- Add task_end2 syscall to allow pthread_exit-like retval.
- Add/maintain task states.
- Create task parent/child tracking tree.
- Add task_detach function.
- Implement wait syscalls.
Make task_exec caller the parent of spawned task:
Previously the task_exec call caused a message to the
VFS task, which called task_create and returned the tid
in response to the message. This causes the parent of
the spawned task to appear to be the VFS task.
Modify task_exec / VFS handling to instead return the
entry point address on the message and have task_exec call
task_create directly itself.
