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

remove alist, switch to a convenient way to traverse
the physical address directly.
At the same time, we can use `gurad` to mark whether
it is free or alloc or out of bounds check

the mempool_alloc and mempool_free function are duplicate with the
mempool method that provided in optee_os, in order to port optee_os, so
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

Add a new field to record the global on the basis of mm_backtrace.
When using alloc, the field is incremented by 1,
so that the memory usage can be dumped within the range

This change introduce 2 items:
1. If the size of the space requested is 0, the behavior is implementation-defined:
either a null pointer shall be returned, or the behavior shall be as if the size
were some non-zero value, except that the behavior is undefined if the returned
pointer is used to access an object.
Change the behavior to be similar to Linux and Android and allocates an object
of a minimum size instead of returning null pointer.

2. The description of realloc() has been modified from previous versions of this
standard to align with the ISO/IEC 9899:1999 standard. Previous versions explicitly
permitted a call to realloc (p, 0) to free the space pointed to by p and return
a null pointer. While this behavior could be interpreted as permitted by this
version of the standard, the C language committee have indicated that this
interpretation is incorrect. Applications should assume that if realloc() returns
a null pointer, the space pointed to by p has not been freed. Since this could lead
to double-frees, implementations should also set errno if a null pointer actually
indicates a failure, and applications should only free the space if errno was changed.
Do not free memory of zero-length reallocation is requested
