1. bin and kbin folders are dynamically generated
2. Context comes before depend, so the bin and kbin folders are created in the context construction phase. When the depend process comes, each library is downloaded, and a relative bin/xxx and kbin/xxx directory is created for each library to place files. This is to prevent duplicate file names.

Since there are some patches that need to be loaded manually, the original method is rather confusing. Now these patches that need to be loaded manually are classified into various cxx library folders, and each dynamically downloaded cxx library is moved down one directory to make the directory structure clearer.

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.

The reason for removing math.h is that undefining __GLIBC__ does not take effect. By default, sim will use the toolchain's math library and undef __GLIBC__ in the source file.

Some chips have different memory addressing spaces for the same
region. This is true, for instance, for ESP32-S3: the same memory
region can be accessed using the data bus or the data bus using
different address ranges. The instruction bus, however, requires
word-aligned access. That being said, it is recommended to use the
data bus while copying sections to the text heap to avoid any
illegal access using the instruction bus address which will be
later used to run the program.

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

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).

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
