Prepare for multiple IPv6 addresses per net device, then we can notify
add/remove of a single address later.

1. Both IPv6 addresses and net masks should be stored in network byte
order
2. Fix last 2 bytes of mask applying (although it seldom triggers)

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

Using void pointers in arithmetic operations is a GCC extension, it is
not supported by the standard. Because what is the size of a void ?
adapts to third-party code compilation. in the process of porting ConnMan,
multiple control message options are enabled, such as IPV6_RECVPKTINFO and
IPV6_RECVHOPLIMIT, so I changed the Filling implementation of the control
message.

The priorities for finding a network adapter are as follows:
1. if laddr is not ANY, use laddr to find device;
2. if laddr is ANY, and bound index is not 0, use bound index
to find device;
3. if laddr is ANY and no device is bound, use raddr to find
device.

CONFIG_NET_ARCH_CHKSUM, move these functions to the common header

Summary:
- The critical section was added in Mar 2018 to improve
stability in SMP mode
- However, I noticed that this critical section is no longer
needed
Impact:
- None
Testing:
- Tested with spresense:wifi_smp and spresense:rndis_smp
