the spdk_thread is scheduled or the reactor is set
into interrupt mode.

7cc83b6258 Revert "lib/event: do not spawn a thread for each reactor"
This reverts commit 72eed604b4.

spdk_vhost_init() relies on having a thread on each reactor.
Without the revert, every vhost controller is created on the same
core and even passing --cpumask when creating does not affect it.

Proper fix would be to change spdk_vhost_init(),
but would require additional testing. For now revert the patch
that spawned always idle threads.

reactor into interrupt mode or poll mode, also set every
notify_cpuset on all reactors for consistency.
It can be used by RPC method or scheduler to set
reactor to interrupt mode while workload is lightweight.

Currently, this function is limited that the specific
reactor should have no attached spdk_thread.

- singlethreaded, but can be made multithreaded.
  By being singlethreaded, we don't waste time,
  because reactors are not paused during rescheduling,
  but we do make statistics less up to date

ea2000cf56 event: disable cpumask check
cpumask can be changed by spdk_thread_set_cpumask()
during the time that event takes before it arrives
on _schedule_thread() function, which would make the
function assert(false), even though that is ~ok~.

Currently, that can happen right after thread is created
or between two successive calls to spdk_thread_set_cpumask().
But most importantly, it will constantly happen if we
introduce rescheduler.

This patch just disables the check for now.

e9aec6746a lib/thread: thread_poll() polls until the exiting thread is exited
Extract _spdk_thread_exit() from spdk_thread_exit() and
_spdk_thread_poll() calls _spdk_thread_exit() if the thread is in
the exiting state. spdk_thread_exit() changes to move the state to
the exiting state. The spdk_thread_poll() loop will end after the
thread moves to the exited state because the caller of
spdk_thread_poll() will check if the thread is in the exited state,
and break the loop if true.

If the user does not call spdk_thread_exit() explicitly, the reactor
has to terminate all existing threads at its shutdown. In this case,
multiple threads may have some dependency to release I/O channels or
unregister pollers. So the reactor has the large two loops, the first
loop calls spdk_thread_exit() on all threads, the second loop calls
spdk_thread_destroy() if exited or spdk_thread_poll() otherwise for
each thread until all threads are destroyed.

Besides, change the return value of spdk_thread_exit() to return
always 0. Keep it for ABI compatibility. Change ERRLOG to INFOLOG
for _spdk_thread_exit() because it is called repeatedly now. Remove
the check of I/O reference count from _spdk_thread_exit() because
_free_thread() cannot free I/O channel. Refine the unit test
accordingly.

Fixes issue #1288.

will move thread to exiting, thread_poll() will move thread from
exiting to exited, thread_is_exited() will detect the threadis exited,
and then call thread_destroy().

So change all places as a preparation.

c9da0aecdc lib/thread: Ignore spdk_thread_exit() call after moving exited
Previously the caller had to check if thread is not exited when
it calls spdk_thread_exit().

Subsequent patches will change return type of spdk_thread_exit()
to void, and so include the check int spdk_thread_exit() in this
patch.

If spdk_thread_exit() is called when the thread is already exited,
collect INFOLOG and return normally.

This will make the next patch a little easier.
