if driver complete unlink ops, we need to call it to release some resource,
otherwise, it will only remove inode.

A segmentfault might happen when read/write/unlink ops called without an open
ops called because it bind ept's ops in rpmsgblk_open_handler.

The memory allocated with strdup and asprintf is done via lib_malloc
so we need to use lib_free to deallocate memory otherwise the assertion
"Free memory from the wrong heap" is hit with flat mode and user separated
heap enabled mode.

Both the device and the pipe used the FSNODEFLAG_TYPE_DRIVER type before,
and now add an independent pipe type

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

This change reflects that the geometry isn't related to the largest
allocatable unit on the platform.
Calls to read and write block devices are also affected and have
been updated.
on the other hand, open/nx_open call file_open instead

Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/driver, fs/aio, fs/nfs, crypto/, and boards/.
Please note: The modified file under fs/nfs generates several " Mixed case identifier found" errors. Please ignore these. These cannot be fixed without changes to numerous other files. They also follow a non-standard convention that is used many files: Using lower case structure names in custom SIZEOF_ definitions.
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/inode. Utility functions under fs/incode were modified so the changes do extend to other fs/ sub-directories as well.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
