reboot: add reboot infrastructure Add the REBOOT kconfig option, along with the sys_reboot() API. This infrastructure is not enough to actually perform a reboot. Architecture/platform code must be provided as well, in the form of a sys_arch_reboot() function.

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

kernel: replace all remaining nanokernel occurances replace include <nanokernel.h> with <kernel.h> everywhere and also fix any remaining mentions of nanokernel. Keep the legacy samples/tests as is.

cleanup: include/: move misc/printk.h to sys/printk.h move misc/printk.h to sys/printk.h and create a shim for backward-compatibility. No functional changes to the headers. A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES. Related to #16539 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

include/system_timer.h: Timer API cleanup Rename timer driver API functions to be consistent. ADD DOCS TO THE HEADER so implementations understand what the requirements are. Remove some unused functions that don't need declarations here. Also removes the per-platform #if's around the power control callback in favor of a weak-linked noop function in the driver initialization (adds a few bytes of code to default platforms -- we'll live, I think).

kernel: add k_cpu_idle/k_cpu_atomic_idle() nano_cpu_idle/nano_cpu_atomic_idle were not ported to the unified kernel, and only the old APIs were available. There was no real impact since, in the unified kernel, only the idle thread should really be doing power management. However, with a single-threaded kernel, these functions can be useful again. The kernel internals now make use of these APIs instead of the legacy ones. Change-Id: Ie8a6396ba378d3ddda27b8dd32fa4711bf53eb36 Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>
