e28b311b78 Make each function of SCHED_CRITMONITOR independent
There will be a large performance loss after SCHED_CRITMONITOR is enabled.
By isolating thread running time-related functions, CPU load can be run with less overhead.

1825f9534c adjtime: Rewrite implementation to work for RTC and tickless kernel
Previous adjtime() implementation was limited to adjusting system
timer tick period. This commit reimplements the internals to use
a kernel watchdog timer. Platform-independent part of the code now
works also for adjusting hires RTC and tickless timer rate.

User code facing API is unchanged. Architecture code API has changed:
up_adj_timer_period() is replaced by up_adjtime().

Other improvements:

- Support query of remaining adjustment by passing NULL to first
  argument of adjtime(). This matches Linux behavior.

- Improve resolution available for architecture driver, previously
  limited to 1 microsecond per tick. Now 1 nanosecond per second.

0611f39cdc adjtime(): Improve configuration and math
1) Previously adjustments less than 1 microsecond per tick would be
   completely ignored. Now they are applied over a shorter period at
   a rate of 1 us per tick.

2) Previously CLOCK_ADJTIME_PERIOD was in units of 1/100th of second.
   Change to milliseconds to be more generally useful unit.
   Change setting name to CLOCK_ADJTIME_PERIOD_MS to make the unit change
   easier to notice.

3) Previously CLOCK_ADJTIME_SLEWLIMIT was in percentage.
   Most clock crystals have better accuracy than 1%, so the minimum slew
   rate was excessive. Change to CLOCK_ADJTIME_SLEWLIMIT_PPM with setting
   value in parts per million.

4) No need to use floating point math in clock_adjtime.c.

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

360e938fa6 sched: add support for adjtime() interface
This commit adds Linux like adjtime() interface that is used to correct
the system time clock if it varies from real value. The adjustment is
done by slight adjustment of clock period and therefore the adjustment
is without time jumps (both forward and backwards)

The implementation is enabled by CONFIG_CLOCK_ADJTIME and separated from
CONFIG_CLOCK_TIMEKEEPING functions. Options CONFIG_CLOCK_ADJTIME_SLEWLIMIT
and CONFIG_CLOCK_ADJTIME_PERIOD can be used to control the adjustment
speed.

Interfaces up_get_timer_period() and up_adj_timer_period() has to be
defined by architecture level support.

This is not a POSIX interface but derives from 4.3BSD, System V.
It is also supported for Linux compatibility.
