The address needs to be reset only when comparing addition, subtraction, multiplication and division addresses. Otherwise, the original address is always returned or saved.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

The mempool mistakenly considers the heap memory as its own
The recurring scenario only occurs in mempool_deinit
test code in hello_main:
int main(int argc, FAR char *argv[])
{
void *a = malloc(1024*64);
void *d[16];
void *heap = mm_initialize("123", a, 1024 * 64);
for (int i = 0; i < 16; i++)
{
d[i] = mm_malloc(heap,32);
}
for (int i = 0; i < 16; i++)
{
if (d[i] != NULL)
mm_free(heap,d[i]);
}
mm_uninitialize(heap);
free(a);
return 0;
}
and crash backtrace

At the same time, we can use `gurad` to mark whether
it is free or alloc or out of bounds check

we rename the mempool related functions in nuttx

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
