The current implementation requires the use of enter_critical_section, so the source code needs to be moved to kernel space

Use double delim to fix windows native build and give an error:
makefile:132: *** target mode do not include“%”. stop.
In Windows environment DELIM := $(strip \) but \ has two role:
first: \ as directory, and second \ as Escape character, Reference:

Refer to issue #8867 for details and rational.
Convert sigset_t to an array type so that more than 32 signals can be supported.
Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
types,
Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).
This is is a work in progress; a draft PR that you are encouraged to comment on.
CONFIG_SERIAL_TERMIOS only decide whether to support c_cflag field since
many terminal application need the first three fields to work correctly.

Use lib_get_stream() to fetch stdin/stdout/stderr,
since is more easy to works with other language by function call
than export native C structure memory layout.

The POSIX standard dictates that during abnormal termination the functions
registered by atexit() are _not_ called, also flushing the streams is
optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.
This fixes regression issues caused by removal exit() from the kernel.
