reason:
1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

IOB buffer participates in the calculation of the congestion strategy
in the protocol stack, if the iob buffer is exhausted or there are
too many syslog printing tasks, the behavior of the protocol stack
and log printing will unable to determined, this PR will remove support
for iob buffer in syslog

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.
