and now add an independent pipe type

In POSIX standard spec https://pubs.opengroup.org/onlinepubs/7908799/xsh/mqueue.h.html, the field type in mq_attr should be long not size_t. And no logical judgment when mq_maxmsg <= 0 or mq_msgsize <= 0. In this change, i update the field type in mq_attr, and add the missing logical judgment.

If the shm file is removed and a subsequent close, only release shm
object, but inode is leaked. Should decrease refcount to release inode
when unmapped, that matched with refcount increase when mapped.
Another fix that remove the shm file failed.

mmap establish a mapping address space that refer to a tmpfs file,
there are two issues:
1. if the tmpfs file is removed and a subsequent close(), tmpfs_close
will release the backend memory object, use after free errors occur
when operating the mapping memory. We add an extra reference to memory object,
memory will be released when there are no more mappings.
2. if unmap only a portion of the memory, fix the bug that adds another map.
Use realloc and shrink the mapping memory instead.
The fix pass LTP posix case mmap/10-1.c and mmap/12-1.c

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.

Follow the POSIX specification in https://pubs.opengroup.org/onlinepubs/9699919799/functions/sem_open.html, update the logic for condition that the semaphore name length is greater than PATH_MAX or a component length is greater than NAME_MAX.

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)
