Summary:
Because stdio.h references stdatomic.h in MVSC, it internally declares mbstate_t, leading to redeclarations during compilation.

Summary:
This change mainly appears in the compilation environment of MVSC
Since MVSC supports the c++11 standard in VS2019 preview3 (https://en.cppreference.com/w/cpp/compiler_support/11), we can do static initialization using the c++11 approach
atomic_int a = 1

Summary:
1. use nuttx/atomic.h instead of stdatomic
2. remove CONFIG_HAVE_ATOMIC,because we now support atomic on all platforms
Signed-off-by: chenrun1 <chenrun1@xiaomi.com>
Summary:
1.Modify the conditions for entering different include header files
2.Added pre-definition for _Atomic _Bool when it is missing
3.Added nuttx for stdatomic implementation. When toolchain does not support atomic, use lib/stdatomic to implement it

Summary:
1. Add nuttx/atomic.h in include
2. Use nuttx/atomic.h instead of stdatomic.h in the nuttx directory

When building from git tags, the version number in `include/version.h`
is extracted from the output of `git describe`. While that is correct,
cmake was not configured to strip trailing whitespace from the command
output, which resulted in the version number being `12.5.1\n`.
That broke the generation of `include/version.h`, as the `\n` resulted
in the terminating quote being in a new line. This commit fixes that by
instructing cmake to strip trailing whitespace.
Update internal reference to get the most updated Espressif's
libraries. Those libraries are based on branch `release/v5.1` of
the ESP-IDF and include `v5.1.4` version of it.
obstack_printf and obstack_vprintf should terminate the C string with
null byte but lib_vsprintf doesn't do it. It must be done on top of
that unless we get unterminated string.
This is fix to be consistent with GlibC behavior.
This also includes minor tweak to use obstack_1grow directly instead of
calling obstack_puts.
Add a common method to format backtrace to buffer, so it can be used by both mm, fs and other possoble modules.

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

The benefit of this approach is that in a multi-core AMP system,
a single coredump might contain memory information from other cores.
By analyzing this coredump along with the corresponding ELF files from
the other cores, you can reconstruct the crash site of those other
cores.

If we have a full memory raw dump, we can parse g_tcbinfo, g_npidhash,
and g_pidhash from the ELF to get NuttX thread info,
regardless of the crash dump log file.
