5b1486f9ce fs/procfs: add build config to /proc/version
Currently at runtime it is hard to know the exact build config of
the current NuttX instance. Thus it is inconvenient when there are
multiple configs for the same board. This patch attempts to solve
the issue by adding build config to /proc/version.

0dedbcd4ae task/pthread_cancelpt: Move cancel point handling to libc, data to TLS
This moves task / thread cancel point logic from the NuttX kernel into
libc, while the data needed by the cancel point logic is moved to TLS.

The change is an enabler to move user-space APIs to libc as well, for
a coherent user/kernel separation.

46b0f6d6ee fdt: Add initial FDT support and procfs for userspace export
VELAPLATFO-12536

This provides the initial hooks for Flattened Device Tree support
with QEMU RV. It also provides a new procfs file that exposes the
fdt to userspace much like the /sys/firmware/fdt endpoint in Linux.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw

Nodes in the fdt are not yet usable by the OS.

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

717bb04cb7 Increase the number of real time signals. Two is not enough.
Refer to issue #8867 for details and rational.

Convert sigset_t to an array type so that more than 32 signals can be supported.

Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
  types,

Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).

This is is a work in progress; a draft PR that you are encouraged to comment on.
