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.

Summary:
If we disable LIB_PATHBUFFER_MALLOC, that when the path buffer is insufficient, NULL is returned to avoid applying for a buffer from the heap.

Summary:
1.Modify the conditions for entering different include header files
2.Added pre-definition for _Atomic _Bool when it is missing
3.Added nuttx for stdatomic implementation. When toolchain does not support atomic, use lib/stdatomic to implement it

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.
Summary:
Since there is a default definition for CONFIG_SMP_NCPUS in sys/types.h, we can remove #ifdef and return CONFIG_SMP_NCPUS directly.

Summary:
1.Remove the macro definition of getnproc in sysinfo
2.New get_nprocs_conf and get_nprocs interfaces, return CONFIG_SMP_NCPUS, return 1 when not defined

Summary:
When the deleted path is a file, the return value of get_errno is -EISDIR, so in Condition Two
(get_errno() ! = EPERM && /* .... . try to remove it. */
rmdir(path) ! = 0)
The judgment holds directly, so it can't actually execute to rmdir

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.
