1. as we can use fork to implement vfork, so we rename the vfork to
fork, and use the fork method as the base to implement vfork method
2. create the vfork function as a libc function based on fork
function

armv8-m/arm_securefault.c:69:3: warning: implicit declaration of function 'syslog_flush'; did you mean 'syslog_like'? [-Wimplicit-function-declaration]
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 small fix ensures all DMA pointers are correctly reseted during
DMA setup (when the driver is opened). Without this there could be rare
occurrence of driver pointer to incorrect (invalidate) DMA buffer and thus
saving incorrect characters to upper layer.

Circular buffer does not use DMA linked list therefore function
sam_freelinklist() cannot be called as it would fail on assertion (csa
not defined). Peripheral that calls DMA should care of buffer invalidation
instead.
