9773fb9867 libc/stdlib: Check if there is next char before assuming octal
When *pptr/ptr is "0" and base is 0, lib_checkbase() returns the error base 8(should be 10).
e.g. `strtoul("0", &endptr, 0);`

2a5f48c3fd libs/libc/stdlib: fix strtoul,strtoull bugs when value outside range
Prototype:
  unsigned long strtoul(FAR const char *nptr, FAR char **endptr, int base);
  unsigned long long strtoull(FAR const char *nptr,  FAR char **endptr, int base);

If endptr is not NULL, strtoul()/strtoull() should store the address of the first
invalid character in *endptr. And if the correct value is outside the range of
representable values, {ULONG_MAX} or {ULLONG_MAX} shall be returned and errno set
to [ERANGE].

With such code:
  strtoul("34592348345343453453455645765736575865767", &endptr, 10);

It indeed returns ULONG_MAX and sets errno to ERANGE. But after strtoul
return, endptr points to "3455645765736575865767", not NULL.

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

07039b8a36 lib_abort.c: Change call to userspace exit() into syscall _exit()
The POSIX standard dictates that during abnormal termination the functions
registered by atexit() are _not_ called, also flushing the streams is
optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.

This fixes regression issues caused by removal exit() from the kernel.

  output:num is 1249835483136.000000
