of disabling interrupts (irq), trylock, and spinlock.

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.

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.
