If libcxxabi is not enabled, the toolchain default implementation will be used. However, arm-gcc does not enable thread
support by default, which will cause errors in a multi-threaded environment.
libcxx depends on pthread_key_create

In the following code, even though the application does not use exceptions, an exception is still thrown in libcxx
If libcxxabi is not enabled, the toolchain default implementation will be used. However, arm-gcc does not enable thread
support by default, which will cause errors in a multi-threaded environment.
Therefore, we need to use libcxxabi to ensure normal functions in a multi-threaded environment.

Some domains have a lot of IPv6 addresses. Because of that, it is
not possible to get the IPv4 address with getaddrinfo.
This change separate IPv4 and IPv6 cache size limit to enable to
get both IP addresses.
There are 2 CMake compile errors during the protected build mode. One is forget to add library for nuttx_user, another is the wrong macro used when compile wqueue.

The standard describes trylock as follows, trylock should never cause the system to stop running:
The pthread_mutex_trylock() function shall be equivalent to
pthread_mutex_lock(), except that if the mutex object referenced by
mutex is currently locked (by any thread, including the current thread),
the call shall return immediately.

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.

This is a tool for associating discrete IDs with addresses.
This tool is implemented through the red-black tree method provided by <sys/tree.h>, and the time complexity when calling, searching, and deleting is optimized to O(logn)
The implementation is the moving node operation of two red-black trees
1. When applying for a node, it will first check whether there is an available node in the "removed" tree. If so, the memory address of the node will be reused and moved to the "alloced" tree.
2. If the "removed" tree is an "empty tree", then the node will be requested from the memory and added to the "alloced" tree
3. Similarly, when removing a node, we set the address pointed to in the node to "NULL" and move it to the "removed" tree. Next time we alloc the node, we can reduce the overhead caused by memory application
For now, we still have something that can be optimized, and that is the memory elimination mechanism of the "removed tree". The current implementation will only release all the content under the "removed" tree when the idtree is destroyed.

The ELF loader needs to load the app into the memory before
executing it from the same location. As expected, this memory space
should be able to execute code. For architectures containing data
and instruction buses, the instruction bus may not be able to be
accessed in a non-aligned way, which is usually required when
copying data to that location. Eventually, this same memory space
can be accessed through the data bus, using different address
ranges. This commit enables accessing the memory through the data
bus to copy the app's data before executing it when
`CONFIG_ARCH_HAVE_TEXT_HEAP_WORD_ALIGNED_READ` is enabled.
To solve some compilation issues encountered during the porting of
third-party libraries, this function has been added.
