when usrsock client try to connect usrsock server local_loop
socket with an invalid port, server cannot find a listener conn
to handle this connet request, then it will response a TCP_RESET
packet via nuttx existing processing, when before conn recv this
RESET packet, it will trigger usrsock_rpmsg_server poll return
and send REMOTE_CLOSE event to usrsock client.
so usrsock connect_event fucntion need handle this event.

Support ICMP ECHO REQUEST & REPLY. Id of ICMP is processed like port of TCP in NAT. However, our ICMP stack doesn't have a method to manage id allocation like tcp_selectport(), the id is set by apps (like icmp_ping.c) without conflict avoidance, so not adding such conflict avoidance logic to ICMP stack when implementing NAT.

Add basic functions for NAT (NAPT), remaining some logic unimplemented (UDP, ICMP, port assignment, etc). NAT for TCP can work now (unless port conflicts).

Since a separate work will add 24 bytes to each conn instance,

* net/netdev/netdev_ioctl.c:
(netdev_ifr_ioctl): The ioctl SIOCGIFHWADDR provides the hardware
address (e.g., Ethernet MAC, etc.) of a network interface. It is
based on Linux. (BSD-based systems don't have this ioctl.) The Linux
implementation sets sa_family to ARPHRD_ETHER for Ethernet and IEEE
802.11 interfaces [1]. NuttX was setting it to NET_SOCK_FAMILY for
these interface types as well as 6LoWPAN and PKTRADIO; this was
incorrect and also the value of NET_SOCK_FAMILY varies based on
Kconfig settings. Correcting this to ARPHRD_ETHER for Ethernet and
IEEE 802.11 and ARPHRD_IEEE802154 for 6LoWPAN and PKTRADIO.
References:
[1] 'man 7 netdevice' on Linux.
* net/netdev/netdev_ioctl.c:
(netdev_ifr_ioctl): The ioctl SIOCSIFHWADDR sets the hardware address
(e.g., Ethernet MAC, etc.) of a network interface. Radio devices may
have different lengths of hardware addresses, such as
NET_6LOWPAN_EADDRSIZE (8), NET_6LOWPAN_SADDRSIZE (2), or
RADIO_MAX_ADDRLEN (8). Also, Kconfig CONFIG_PKTRADIO_ADDRLEN allows
the user to set any arbitrary size. Note that while the sister ioctl
SIOCGIFHWADDR "get hardware address" copies
`dev->d_mac.radio.nv_addrlen` bytes, SIOCSIFHWADDR was copying
NET_6LOWPAN_ADDRSIZE bytes unconditionally. Depending on which radio
is used, this could be incorrect. Fixing it to use
`dev->d_mac.radio.nv_addrlen` for SIOCSIFHWADDR as well. Also adding
DEBUGASSERT to ensure this is within bounds of source and
destination of the copy.

When the free connection list is unenough to alloc a new instance,
the TCP stack will reuse the currently closed connection, but if
the handle is not released by the user via close(2), the reference
count of the connection remains in a non-zero value, it will cause
the assertion to fail, so when the handle is not released we should
not use such a conn instance when being actively closed, and ensure
that the reference count is assigned within the net lock protection

When a Netlink response is issued, which a task is currently polling for
on the corresponding AF_NETLINK socket, then the poll call will return
with a ENOENT error. This is due to the fact that the Netlink response
notifier is automatically torn down after the notification.
Fixed by making netlink_notifier_teardown a best-effort function that
does not return a result code.

According to POSIX the length of the source address of the received
message shall be stored in the object pointed to by the address_len
argument.
This patch fixes two places where this did not happen correctly.

Note: some applications like mbedtls uses F_GETFL to confirm
the nonblock-ness of the socket. This is critical for such
applications.

socket flags(s_flags) is a global state for net connection
remove the incorrect update for stop monitor
2. do not start the tcp monitor from duplicated psock
