kernel/arch: consolidate tTCS and TNANO definitions There was a lot of duplication between architectures for the definition of threads and the "nanokernel" guts. These have been consolidated. Now, a common file kernel/unified/include/kernel_structs.h holds the common definitions. Architectures provide two files to complement it: kernel_arch_data.h and kernel_arch_func.h. The first one contains at least the struct _thread_arch and struct _kernel_arch data structures, as well as the struct _callee_saved and struct _caller_saved register layouts. The second file contains anything that needs what is provided by the common stuff in kernel_structs.h. Those two files are only meant to be included in kernel_structs.h in very specific locations. The thread data structure has been separated into three major parts: common struct _thread_base and struct k_thread, and arch-specific struct _thread_arch. The first and third ones are included in the second. The struct s_NANO data structure has been split into two: common struct _kernel and arch-specific struct _kernel_arch. The latter is included in the former. Offsets files have also changed: nano_offsets.h has been renamed kernel_offsets.h and is still included by the arch-specific offsets.c. Also, since the thread and kernel data structures are now made of sub-structures, offsets have to be added to make up the full offset. Some of these additions have been consolidated in shorter symbols, available from kernel/unified/include/offsets_short.h, which includes an arch-specific offsets_arch_short.h. Most of the code include offsets_short.h now instead of offsets.h. Change-Id: I084645cb7e6db8db69aeaaf162963fe157045d5a Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>

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.

#include <arch/cpu.h>
kernel: expose struct k_thread implementation Historically, space for struct k_thread was always carved out of the thread's stack region. However, we want more control on where this data will reside; in memory protection scenarios the stack may only be used for actual stack data and nothing else. On some platforms (particularly ARM), including kernel_arch_data.h from the toplevel kernel.h exposes intractable circular dependency issues. We create a new per-arch header "kernel_arch_thread.h" with very limited scope; it only defines the three data structures necessary to instantiate the arch-specific bits of a struct k_thread.
