The FIOC_FILEPATH ioctl needs rf->rf_path, which is not initialized for
dup'ed romfs file and cause problems.

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

since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible

- Add mmap into file_operations and remove it from ioctl definitions.
- Add mm_map structure definitions to support future unmapping
- Modify all drivers to initialize the operations struct accordingly

- Add truncate into file_operations
- Move truncate to be common for mountpt_operations and file_operations
- Modify all drivers to initialize the operations struct accordingly

The default size of file cache is size of a sector, it may
not be good size for optimizing read/write speed in physical
device. So we can set the config according to speed test profile
to optimize access IO speed.

This PR corrects an error in the ROMFS file system. The error occurred after following a hard link (depending on how the ROMFS image is organized). The error occurred because some of the information buffered before following the links was stale and, hence, out of sync after following the hard link. This would cause random errors when paths containing hardlinks were used with ROMFS.
This PR resolves Issue #1543. Please compare the following output with the output in Issue #1543 to see how the problem was resolved:
