reason:
The old implementation of the SMP call, even when using the "no wait" parameter,
could still result in waiting, if invoking it within a critical section
may lead to deadlocks. Therefore, in order to implement a truly asynchronous SMP
call strategy, we have added nxsched_smp_call_async.

We decouple semcount from business logic by using an independent counting variable,
which allows us to remove critical sections in many cases.

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).
Summary:
add check !defined(__STDC_NO_ATOMICS__)
If the macro constant __STDC_NO_ATOMICS__(C11) is defined by the compiler, the header <stdatomic.h>, the keyword _Atomic, and all of the names listed here are not provided.

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.)
adapts to third-party code compilation. in the process of porting EtherCAT,
we encounter some situations where the structure is not defined, or the
returned data types do not match the expectations. Refer to the EtherCAT
implementation of other systems and add relevant definitions.
