This patch fixed userspace headers conflict. Architecture-related definition and API should not be exposed to users.

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.

This primarily fixes allocated memory overrun due to invalidly
calculated limit of the chunk. The function here allocates chunk of size
that includes required header. The error was that size of the chunk was
invalidly again added when limit was being calculated. This was causing
memory overrun and issues especially with object growing (reallocation).
The secondary fix here is to the algorithm that rounds the required size
to the multiple of chunk size. In short chunk size must be reduced by
one to get the correct mask. The condition that was generating the mask
was also invalid because it must perform shift with at most one less
than number of bits (not bytes).
1. Since the implementation of gcov has changed since clang17, versions before clang17 need to use the libunwind.a file

currently, nuttx implements readv/writev on the top of read/write.
while it might work for the simplest cases, it's broken by design.
for example, it's impossible to make it work correctly for files
which need to preserve data boundaries without allocating a single
contiguous buffer. (udp socket, some character devices, etc)
this change is a start of the migration to a better design.
that is, implement read/write on the top of readv/writev.
to avoid a single huge change, following things will NOT be done in
this commit:
* fix actual bugs caused by the original readv-based-on-read design.
(cf. https://github.com/apache/nuttx/pull/12674)
* adapt filesystems/drivers to actually benefit from the new interface.
(except a few trivial examples)
* eventually retire the old interface.
* retire read/write syscalls. implement them in libc instead.
* pread/pwrite/preadv/pwritev (except the introduction of struct uio,
which is a preparation to back these variations with the new
interface.)
1. enable CONFIG_BUILTIN_COMPILER_RT to built libclang_rt.builtins-xxx.a and no longer use the compiler's built-in
2. Modify clang version acquisition to get two decimal points
3. It has been ported to support four architectures: ARM, ARM64, RISCV, and x86_64, among which ARM has been validated

This fixes issue where empty and unallocated sections are left without
a VMA. Some relocations depend on the section VMA being set even if there
is no data there, as the binary can refer to the symbols. Linker defined
symbols do not contain data -> they can produce empty sections.
This issue is seen when building a loadable file which declares _sctors /
_sdtors linker defined symbols for ctor/dtor sections which are empty.
crt0 references these symbols, so they need to be relocated, but the
section VMA is not set -> they go outside of the addressable range of the
user binary causing a potential crash.
In circbuf_get_read/writeptr, when circbuf is full, off == pos, and
*size = off - pos = 0. So add circbuf_is_full() condition to return
correct *size.
