Adds support for timestamping received UDP packets, either in
hardware or in kernel. Builds on the existing support of SO_TIMESTAMP
for SocketCAN.
Implementation uses CLOCK_REALTIME for timestamping to match the
behavior of Linux. This could be made configurable in future if needed.
In tcp protocol, if no ports are bound, Add random ports during the listening phase

TEST_IMPL(tcp_listen_without_bind) {
int r;
uv_tcp_t server;
r = uv_tcp_init(uv_default_loop(), &server);
ASSERT(r == 0);
r = uv_listen((uv_stream_t*)&server, 128, NULL);
ASSERT(r == 0);
MAKE_VALGRIND_HAPPY();
return 0;

There're some apps trying to set too large SO_SNDBUF and SO_RCVBUF, which may use all IOBs in one socket and block all other network traffic.
Note:
Linux silently limits SO_SNDBUF to be less than `sysctl_wmem_max`, so we can also do this limit without returning any error.

The third-party library we are porting will send and receive ICMPV6 messages
(router_advert / router_solicit / neighbor_advert / neighbor_solicit etc.)
from the user mode itself, so we added the SOCK_RAW related implementation
for ICMPV6.

Problem:
A SOCK_CTRL socket may be led to udp_pollsetup but never reaches
udp_pollteardown, it seems that we shouldn't call udp_pollsetup for
other socket types.

SOCK_CTRL is added to provide special control over network drivers
and daemons. Currently, SOCK_DGRAM and SOCK_STREAM perform this control,
but these use socket resources. In the case of usersocket in particular,
this is a waste of the device's limited socket resources.

1. remove the unnecessary interfaces tcp_close_monitor()
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
the tcp monitor has already registered in connect callback
------------------------------------------------------------
This patch also fix the telnet issue reported by:
https://github.com/apache/incubator-nuttx/pull/5434#issuecomment-1035600651
the orignal session fd is closed after dup, the connect state
has incorrectly migrated to close:
drivers/net/telnet.c:
977 static int telnet_session(FAR struct telnet_session_s *session)
...
1031 ret = psock_dup2(psock, &priv->td_psock);
...
1082 nx_close(session->ts_sd);

Implement si_send/sendto/recvfrom with si_sendmsg/recvmsg, instead of
the other way round.

MSG_DONTWAIT (since Linux 2.2)
Enables nonblocking operation; if the operation would block, the
call fails with the error EAGAIN or EWOULDBLOCK. This provides
similar behavior to setting the O_NONBLOCK flag (via the fcntl(2)
F_SETFL operation), but differs in that MSG_DONTWAIT is a per-call
option, whereas O_NONBLOCK is a setting on the open file description
(see open(2)), which will affect all threads in the calling process
and as well as other processes that hold file descriptors referring
to the same open file description.
