1. add lib_fork api in libs/libc, we need a fork() api to implement the
fork relative method, such as pthread_atfork
2. rename the assembly fork entry function name to up_fork(), and rename
the up_fork() to arch specific name, such as
sim_fork()/arm_fork()/mips_fork() etc.

If -fstack-protector-all is enabled, gcc linker will need GCC
SSP(Stack Smashing Protector) support, Since the implement of SSP
is related to the OS, most of embedded toolchain does not provide
ssp support, so an error will be reported when linking:
enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES
arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory
arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory
https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985
Since nuttx has already implemented SSP related hook functions,
so in this PR, we filter out this option in the link phase to ensure that
the implementation of lssp/lssp_nonshared will not be referenced

When debugging the actual dns resolution failure encountered, it is found
that if you know the address of dnsserver, the difficulty of debugging the
problem is reduced.

you can debug nuttx through any transport layer (serial port, network etc.),
currently supports the following functions:
1. Read and write registers
2. Read and write memory
3. Switch thread and read stack information
Future support plans:
1. Support breakpoint, watch point (requires architecture support).

1. the getpgid function can help to pass the
ltp/open_posix_testsuite/killpg related testcases
2. NuttX do not support process group, so we use the process id as
process group id
3. the implementation are referred to: https://pubs.opengroup.org/onlinepubs/9699919799/functions/getpgid.html

sysconf add param _SC_THREAD_STACK_MIN deal
make the pthread_exit pass the ltp/open_posix_testsuite/pthread_exit/1-2.c testcase
(1) in pthread_exit/1-2.c testcase, if sysconf(_SC_THREAD_STACK_MIN) % sysconf(_SC_PAGESIZE) is not zero, will report error and test failed, so set CONFIG_PTHREAD_STACK_MIN as DEFAULT_MM_PGSIZE`s default value.
(2) in function sysconf add param _SC_THREAD_STACK_MIN deal.

1. as we can use fork to implement vfork, so we rename the vfork to
fork, and use the fork method as the base to implement vfork method
2. create the vfork function as a libc function based on fork
function

In nuttx function pthread_rwlock_init param attr is useless, so remove it to make rwlock_init pass rwlock_init/1-1.c and rwlock_init/3-1.c testcases.

Prototype:
unsigned long strtoul(FAR const char *nptr, FAR char **endptr, int base);
unsigned long long strtoull(FAR const char *nptr, FAR char **endptr, int base);
If endptr is not NULL, strtoul()/strtoull() should store the address of the first
invalid character in *endptr. And if the correct value is outside the range of
representable values, {ULONG_MAX} or {ULLONG_MAX} shall be returned and errno set
to [ERANGE].
With such code:
strtoul("34592348345343453453455645765736575865767", &endptr, 10);
It indeed returns ULONG_MAX and sets errno to ERANGE. But after strtoul
return, endptr points to "3455645765736575865767", not NULL.

For "%e" conversion, the exponent always contains at least two digits.
That means if the value is zero, the exponent is 00, not 0.
Such as code:
printf(buffer, sizeof(buffer), "%e", 1.232323232323);
printf(buffer, sizeof(buffer), "%e", 12.32323232323);
printf(buffer, sizeof(buffer), "%e", 123.2323232323);
Expected output:
1.232323e+00
1.232323e+01
1.232323e+02
But real output:
1.232323e+0
1.232323e+1
1.232323e+2

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
