since the same function can be achieved by mount:
mount(NULL, "/mnt/unionfs", "unionfs", 0,
"fspath1=/mnt/path1,prefix1=prefix1,"
"fspath2=/mnt/path2,prefix2=prefix2");

while iterate throuh all mapping memory to munmap and release,
the last entry is NUlL.
We need differentiate the case with invald entry at the first.
The fix is to pass ltp shm related cases.

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

Summary:
- Some network drivers such as GS2200M do not support to bind
a local port for TCP client socket. In this case, this config
disables to bind the port.
- See also https://github.com/apache/nuttx/pull/3707
Impact:
- None
Testing:
- Tested with spresense:wifi_smp (Kconfig will be updated later)
- Tested with sabre-6quad:netnsh_smp (QEMU)

Testing for overflow by adding a value to a variable to see if it "wraps
around" works only for unsigned integer values, because signed overflow
has undefined behavior according to the C and C++ standards.

If sendfile() is called with a zero count, it will nevertheless
try to send the data. This is mostly meaningless, it causes
waste of resources, and in some cases delays.
This commit adds special handling for this case, allowing
sendfile to return immediately zero. The new behavior is
in line with the Linux variant of sendfile.
Directly return -ENOTTY in rpmsgxxx_ioctl() when the command is
not supported to avoid fdsan command FIOC_SETTAG and FIOC_GETTAG
pass to the rpmsg dev/mtd/blk server with CONFIG_FDSAN enabled.

In embedded development environments, due to the lack of address isolation between processes,
fd may be passed between processes and lead to misuse,
We have designed an fd cross-process automatic detection tool,
fdcheck_protect returns the fd containing the pid information,
indicating that the ownership of the current fd belongs to the pid and is not allowed to be used by other processes.
fdcheck_restore will obtain the true fd and check if the ownership of the fd is legal
For ease of understanding, let's give an example where
the following information is represented in 32-bit binary format
fd 00000000 00000000 00000000 10001010
pid 00000000 00000000 00000011 01010101
ret 00000000 00000011 01010101 10001010
