6ee9ec7656 build: add initial cmake build system
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

0476e30a6d mm/kmm_map: Add support to dynamically map pages into kernel virtual memory
This adds functionality to map pages dynamically into kernel virtual
memory. This allows implementing I/O remap for example, which is a useful
(future) feature.

Now, the first target is to support mapping user pages for the kernel.

Why? There are some userspace structures that might be needed when the
userspace process is not running. Semaphores are one such example. Signals
and the WDT timeout both need access to the user semaphore to work
properly. Even though for this only obtaining the kernel addressable
page pool virtual address is needed, for completeness a procedure is
provided to map several pages.

5a298e8685 mm: memory allocations return valid pointer when request 0 size
This change introduce 2 items:
1. If the size of the space requested is 0, the behavior is implementation-defined:
   either a null pointer shall be returned, or the behavior shall be as if the size
   were some non-zero value, except that the behavior is undefined if the returned
   pointer is used to access an object.

   Change the behavior to be similar to Linux and Android and allocates an object
   of a minimum size instead of returning null pointer.

   https://pubs.opengroup.org/onlinepubs/9699919799/functions/malloc.html
   https://pubs.opengroup.org/onlinepubs/9699919799/functions/calloc.html
   https://pubs.opengroup.org/onlinepubs/9699919799/functions/realloc.html

2. The description of realloc() has been modified from previous versions of this
   standard to align with the ISO/IEC 9899:1999 standard. Previous versions explicitly
   permitted a call to realloc (p, 0) to free the space pointed to by p and return
   a null pointer. While this behavior could be interpreted as permitted by this
   version of the standard, the C language committee have indicated that this
   interpretation is incorrect. Applications should assume that if realloc() returns
   a null pointer, the space pointed to by p has not been freed. Since this could lead
   to double-frees, implementations should also set errno if a null pointer actually
   indicates a failure, and applications should only free the space if errno was changed.

   Do not free memory of zero-length reallocation is requested

c82f44c4f3 mm/mm_heap: add mempool to optimize small block performance
There are many small memory block in NuttX system, eg: struct tcb_s,
struct inode, etc, and several disadvantages about them:
1.Their frequent allocate and free cause the system memory fragmentation.
2.Since each memory block has an overhead, the utilization of small memory
blocks is relatively low, which will cause memory waste.

So we can use mempool to alloc smallo block, to improve alloc speed
and utilization, to reduce fragmentation.

5c0a5a6627 mm/mempool: support memalign about mempool and mulitple mempool
The memalign is special to multiple mempool because multiple mempool
doesn't support split and shrink chunk operate. So When you alloc a
memory block and find an aligned address in this block, you need to
occupy 8 bytes before the address to save the address of the padding
size and pool to ensure correct use in realloc and free operations.
So we will use bit1 in the previous address of the address to represent
that it is applied by memalign.

   which will benefit l3(IP) layer for multi-MAC(l2) implementation,
   especially in some NICs such as celluler net driver.

new configuration options: CONFIG_NET_LL_GUARDSIZE

CONFIG_NET_LL_GUARDSIZE will reserved l2 buffer header size of
network buffer to isolate the L2/L3 (MAC/IP) data on network layer,
which will be beneficial to L3 network layer protocol transparent
transmission and forwarding

2. Support iob offload to l2 driver to avoid unnecessary memory copy

Support send/receive iob vectors directly between the NICs and l3/l4
stack to avoid unnecessary memory copies, especially on hardware that
supports Scatter/gather, which can greatly improve performance.

48b9a8d6f4 mm/shm: Move the vma allocators to separate functions
This will allow changing the underlying backend, i.e. granule allocator,
to something more efficient, if this is needed later.

Also, it gives easier access to the common SHM book keeping.

458ff380e5 mm/gran: Allow run-time execution of gran_reserve
User can ask for specific granules to be allocated.

This is useful for one thing only: when mmap() is called for a specific
vaddr. The parameter itself is non-sensical, this is just to satisfy
the POSIX standard.
