669619a06a tcp_close: Fix a race with passive close
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.

08e9dff0e9 tcp_close: disable send callback before sending FIN
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

326a8ef0a2 tcp_close_disconnect: don't nullify sndcb
It isn't necessary and I plan to use the value later in
the close processing.

95be9eaf4b net/callback: remove the assert check of conn instance
remove the connection assertion since the instance will be invalid
if the network device has been taken down.

net/netdev/netdev_ioctl.c:

1847 void netdev_ifdown(FAR struct net_driver_s *dev)
1848 {
...
1871       /* Notify clients that the network has been taken down */
1872
1873       devif_dev_event(dev, NULL, NETDEV_DOWN);
...
1883 }

6b413ec241 net/tcp: Fix errors found in build testing.
Author: Gregory Nutt <gnutt@nuttx.org>

    net/tcp: Fix errors found in build testing.

    Recent re-organization moved some functions from net/inet to net/tcp and net/udp.  This include references to nxsem_wait(), SEM_PRIO_NONE, and other internal NuttX semaphore functions.  These all failed to compile because nuttx/semaphore.h was not included in any of the files.
