baabf4bbf3 net/local: fix visual studio Compiler Error C2057
expected constant expression
The context requires a constant expression, an expression whose value is known at compile time.
The compiler must know the size of a type at compile time in order to allocate space for an instance of that type.

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

4f4a00ab1f net/local: fix blocking local sockets
Commit 4d6a8663fa made pipes and
named pipes block when opening for O_WRONLY or O_RDONLY. Local
sockets, however, require `local_open_client_tx` to be non-blocking
to enable the server side to prevent the server side from blocking.
If set otherwise, it would deadly block. This commit sets the FIFO
as non-blocking temporarily, open the TX side and, if originally
blocking - restores it to that state.
