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

f71fb738c5 net/icmp: Save poll device in icmp_poll_s
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.

2e6d0815b2 nuttx/net:Support to PMTUD
RFC 1191
When a router is unable to forward a datagram because it exceeds the
   MTU of the next-hop network and its Don't Fragment bit is set, the
   router is required to return an ICMP Destination Unreachable message
   to the source of the datagram, with the Code indicating
   "fragmentation needed and DF set".  To support the Path MTU Discovery
   technique specified in this memo, the router MUST include the MTU of
   that next-hop network in the low-order 16 bits of the ICMP header
   field that is labelled "unused" in the ICMP specification [7].  The
   high-order 16 bits remain unused, and MUST be set to zero.  Thus, the
   message has the following format:

       0                   1                   2                   3

2. if laddr is ANY, and bound index is not 0, use bound index

3. if laddr is ANY and no device is bound, use raddr to find
   device.

Allocate the device buffer only if the protocol really need to send data.

sending, especially UDP, each iob reserves l2/l3 header in advance

d87620abc9 net: downgrade iob priority of input/udp/icmp to avoid blocking devif
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.

34d2cde8a8 net/l2/l3/l4: add support of iob offload
1. Add new config CONFIG_NET_LL_GUARDSIZE to isolation of l2 stack,
   which will benefit l3(IP) layer for multi-MAC(l2) implementation,
   especially in some NICs such as celluler net driver.

new configuration options: CONFIG_NET_LL_GUARDSIZE

CONFIG_NET_LL_GUARDSIZE will reserved l2 buffer header size of
network buffer to isolate the L2/L3 (MAC/IP) data on network layer,
which will be beneficial to L3 network layer protocol transparent
transmission and forwarding

            -------------------------------------------------

2. Support iob offload to l2 driver to avoid unnecessary memory copy

Support send/receive iob vectors directly between the NICs and l3/l4
stack to avoid unnecessary memory copies, especially on hardware that
supports Scatter/gather, which can greatly improve performance.

new interface to support iob offload:
