kasan does not instrument the assembly function,
so it is checked in advance before calling.
If Kasan is not turned on, the speed and space will
be almost unchanged under compiler optimization.

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

The reason is that libc.h needs to check whether CONFIG is enabled before the corresponding macro is enabled

__dtoa is not used because currently NuttX uses other
function called __dtoa_engine() to do the same thing

Provide a way to only customize specific string operations,
such as for memcpy with the DMA capability by ROM.

Add the `LIBC_PREVENT_STRING_KERNEL` and `LIBC_PREVENT_STRING_USER`
that are meant to be selected by the chip if no libc implementation
is going to be built. If selected, neither NuttX's software version
of the libc nor any architecture-specific implementation will be
built in the kernel or in the userspace, respectively. In this
case, the linker may provide a ROM-defined version of the libc
functions instead.
1.Reduce the default size of task_group_s(~512B each task)
2.Scale better between simple and complex application

drivers/net/ftmac100.c, libs/libc/stdlib/lib_aligned_alloc.c
A continuation of PRs #1507, #1510, and #1512. See Issue #1481 for additional information.
Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
