We have IPV6_UNICAST_HOPS and IPV6_MULTICAST_HOPS in ipv6_setsockopt,
but only IP_MULTICAST_TTL in ipv4_setsockopt. So add IP_TTL support.

When using IOB queue to store readahead data, we use one IOB for each
UDP packet. Then if the packets are very small, like 10Bytes per packet,
we'll use ~1600 IOBs just for 16KB recv buffer size, which is wasteful
and dangerous. So change conn->readahead to a single IOB chain like TCP.
Benefits:
- Using memory and IOBs more efficiently (small packets are common in
UDP)
Side effects:
- UDP recv buffer size may count the overhead
- A little bit drop in performance (<1%, more seek & copy)

if client is a noblocking socket, user can do close when server has not yet
invoke accept interface, so we need remove this socket from server.lc_waiters.
avoid server socket access the freed memory.

Add the proccessing logic of udp socketpair, and modify the
logic of sending and receiving for udp socketpair.
Verification:
- Use the socketpair interface to create a pair of local udp sockets,
and perform read and write operations.

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 udp connection structure contains the field, "domain", which defines which address family it belongs to. Prior to this change, this field was only populated correctly if IPv4 and IPv6 was enabled. As a result, packet information was not processed in udp_recvpktinfo, as expected when the appropriate socket option was enabled.
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
ICMP's conn->dev is changing in icmp_sendmsg, when sending to different
address, or when error occurs (like NETDEV_DOWN). Then the poll callback
cannot be dropped from previous dev in free, because the dev is wrong.
So add dev to struct icmp_poll_s just like struct udp_poll_s.

When a task needs to send data, a callback is allocated and the
transmission is happening in a worker task through devif_send.
Synchronization between the two tasks (sender & worker) is
achieved by a semaphore.
If devif_send fails, this semaphore was never posted, leaving
the sending task blocked indefinitely. This commit fixes this
by checking the return code of netif_send, and posting this
semaphore in case of failure.
Polling then stops, and execution is resumed on the sending
task.

Problem:
When tcp_close_work starts to run in LPWORK, if another event comes and
calls tcp_free before tcp_close_work takes net_lock, the tcp_free will
be called twice and cause double free.

This is a refactored version of the SLIP network driver. Updates
include:
1. The original design started two kernel threads per SLIP device.
The refactored version uses file_poll to essentially be driven
by the UART RX and TX interrupts and pushes work to the low
priority work queue.
2. The SLIP byte un-/stuffing is more efficient now, using memcpy
instead of handling each byte individually.
3. The switch of the old SLIP driver to IOBs caused buffer overwrites
if packets were sent that would not fit into a single IOB. This is
fixed now.
