c3a234fe99 ipv6: Fix source address with many addresses in same network
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.

cb161940c2 udp: Add support for SO_TIMESTAMP
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.

99ee94728a net:add IP_MULTICAST_IF & IPV6_MULTICAST_IF function implementation
refer to https://man7.org/linux/man-pages/man7/ip.7.html
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.

6ee9ec7656 build: add initial cmake build system
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

1072b5b564 net: Limit max value for Send/Recv bufsize
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.
