Root casue:
when do thread exit, need add free stack operation to mm_delaylist,
but in SMP mode, CPU0 thread1 exit, at this time, CPU1 call malloc
and free mm_delaylist.
Fix:
Divide mm_delaylist for per CPU in SMP mode.

Because idle task will call mm_malloc to create some task
and will take sem of mm. But if smp enable, the sem of mm may be
taken by other cpu, so idle may be block because take this sem and crash.

tcp_close disposes the connection immediately if it's called in
TCP_LAST_ACK. If it happens, we will end up with responding the
last ACK with a RST.
This commit fixes it by making tcp_close wait for the completion
of the passive close.

drivers/sensors/hyt271.c:
* struct hyt271_dev_s: Identifier "lock_measure_cylce" was
misspelled. Fix to "lock_measure_cycle" and update all instances
in the file.
* hyt271_mr(), hyt271_cmd(), hyt271_change_addr(),
hyt271_measure_read(), hyt271_thread(): Update instances of the
renamed "lock_measure_cycle" variable and fix various typos in
comments.
For the case when the watchdog is triggering a timeout we did not
correctly reset the GPIO_SDIO_D0.
Without this fix, the SD card can become inaccessible.
It turns out there is no difference in these two files as well as the
reference manual for the registers between the two parts, so it probably
makes sense to unify them
1.fix crash casued by closing the handle during the reading.
2.fix set_interval fail sometime:When fakesensor was activated, csv file is not opened timely, so
the sensor->interval that set_interval() seted will be coverd by
interval form csv file.

This fixes connection closing issues with CONFIG_NET_TCP_WRITE_BUFFERS.
Because TCP_CLOSE is used for both of input and output for tcp_callback,
the close callback and the send callback confuses each other as
the following. As it effectively disposes the connection immediately,
we end up with responding to the consequent ACK and FIN/ACK from the peer
with RSTs.
tcp_timer
-> tcp_close_eventhandler
returns TCP_CLOSE (meaning an active close)
-> psock_send_eventhandler
called with TCP_CLOSE from tcp_close_eventhandler, misinterpet as
a passive close.
-> tcp_lost_connection
-> tcp_shutdown_monitor
-> tcp_callback
-> tcp_close_eventhandler
misinterpret TCP_CLOSE from itself as
a passive close
The current code just leave the window value from the segment
from the peer. It doesn't make sense.
Instead, always use 0.
This matches what NetBSD and Linux do.
(As far as I read their code correctly.)
