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.

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

Devices connected to the same USB bus should have unique function addresses.
This was not true for root hubs with multiple ports. After this change,
enumeration is more reliable on the sama5d3-xplained board when both root hub
ports are used.
This change amounts to using one usbhost_devaddr_s object per root hub
instead of one per root hub port. For the majority of boards only one
root hub port is available so no change in behavior should be expected.
in SMP, signal processing cannot be nested, we use xcp.sigdeliver to identify whether there is currently a signal being processed, but this state does not match the actual situation
One possible scenario is that signal processing has already been completed, but an interrupt occurs, resulting in xcp.sigdeliver not being correctly set to NULL,
At this point, a new signal arrives, which can only be placed in the queue and cannot be processed immediately
Our solution is that signal processing and signal complete status are set in the same critical section, which can ensure status synchronization

Follow the change: https://github.com/apache/nuttx/pull/9151,
if MM_CUSTOMIZE_MANAGER is enabled, heap memory manager in host is used,
for example in sim:asan build.
malloc and related allocation APIs will fall back to host_realloc,
do not free memory of zero-length reallocation. So memory allocations
return valid pointer when request zero size in all sim build.
call stack:
malloc() (mm/umm_heap/umm_malloc.c)
mm_malloc() (arch/sim/src/sim/sim_heap.c)
mm_realloc() (arch/sim/src/sim/sim_heap.c)
host_realloc() (arch/sim/src/sim/posix/sim_hostmemory.c)

The fast-unwind implementation of leak-sanitizer will obtain the
current stack top/bottom and frame address(Stack Pointer) for
backtrace calculation:
https://github.com/gcc-mirror/gcc/blob/releases/gcc-13/libsanitizer/lsan/lsan.cpp#L39-L42
Since the scheduling mechanism of NuttX sim is coroutine
(setjmp/longjmp), if the Stack Pointer is switched, the fast-unwind
will unable to get the available address, so the memory leaks on the
system/application side that cannot be caught normally. This PR will
disable fast-unwind by default to avoid unwind failure.
