Previously ipv6 multi-address support decided packet source
address based on its destination. This doesn't work if NuttX
device has multiple addresses within same subnet.
Instead when a packet is a response to existing connection,
the source address should be based on the destination address
used in the received packet.
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.
Note that user-space related code, like procfs and lifreq related ioctl commands, are not touched in this commit.

IP_MULTICAST_IF (since Linux 1.2)
Set the local device for a multicast socket. The argument
for setsockopt(2) is an ip_mreqn or (since Linux 3.5)
ip_mreq structure similar to IP_ADD_MEMBERSHIP, or an
in_addr structure. (The kernel determines which structure
is being passed based on the size passed in optlen.) For
getsockopt(2), the argument is an in_addr structure.
refer to https://man7.org/linux/man-pages/man7/ipv6.7.html
IPV6_MULTICAST_IF
Set the device for outgoing multicast packets on the
socket. This is allowed only for SOCK_DGRAM and SOCK_RAW
socket. The argument is a pointer to an interface index
(see netdevice(7)) in an integer.

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

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.
