When implementing IPv6-related logic, we found the `net_ipv6_pref2mask`
and `net_ipv6addr_copy` are using different argument order:
```
net_ipv6addr_copy(ifaddr->addr, addr);
net_ipv6_pref2mask(preflen, ifaddr->mask);
```
Change the order to:
```
net_ipv6addr_copy(ifaddr->addr, addr);
net_ipv6_pref2mask(ifaddr->mask, preflen);
```

1. Supporting `SIOCSIFADDR` and `SIOCDIFADDR` with Linux in6_ifreq struct to manage ipv6 addresses.
Ref: https://man7.org/linux/man-pages/man7/netdevice.7.html
2. Supporting alias like 'eth0:0' for multiple IPv6 addresses, to keep previous ioctl `SIOCGLIFADDR`, `SIOCSLIFADDR`, `SIOCGLIFNETMASK` and `SIOCSLIFNETMASK` working.

Note that user-space related code, like procfs and lifreq related ioctl commands, are not touched in this commit.

Compatible with previous usage, because may network drivers are using old member name to print logs, and there's no significant need to change them now.

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

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 is no control over whether a valid index is input when user use
ioctl to get netdev information, so removing this assertion will allow
ENODEV to be returned.

Updated alt1250 driver with regarding to the following changes.
- Add LTE hibernation feature
- Split source code per module
- Some refactoring
- Some bug fixes
We have projects that need to sense ip address changes in time,
and set ip address or clear ip address through netlink
so the relevant implementation is added.
The usage and command structure are consistent with linux

Allocate the device buffer only if the protocol really need to send data.
not all protocols require the driver to prepare additional iob before
sending, especially UDP, each iob reserves l2/l3 header in advance
after prepare write buffer, net device could reuse this entry to send directly

When trying to use iperf2, we found it comsumes all the IOB when sending UDP packets, then devif_poll has no IOB to send the packet out, so speed drops to 0 and never recovers.

Problem:
- `iob_copyout` to `d_buf` doesn't set `io_len` of the IOB, so `devif_poll` failed to copy the data into `buf` by `iob_copyout`
Modification:
- Just Move the IOB in `devif_forward`.

* 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.

* 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.
