b6693065e7 pthread_once: g_lock may lead deadlock 
For programs with the dependencies logic in pthread_once callback , using global locks may cause deadlock:

task A
pthread_once()
|
|-> nxrmutex_lock(&g_lock);
 -> init_routine(); // callback to wait task B
                                                  task B
                                                  pthread_once()
                                                  |
                                                   ->nxrmutex_lock(&g_lock); // Deadlock
                                                   ->init_routine(); // hold resource to wake up task A

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

962dfaf651 libc/pthread: Return EINVAL when input parameter incorrect at pthread_once 
https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_once.html

If an implementation detects that the value specified by the once_control
argument to pthread_once() does not refer to a pthread_once_t object
initialized by PTHREAD_ONCE_INIT, it is recommended that the function
should fail and report an [EINVAL] error.
