Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types. This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies. We also convert the PRI printf formatters in the arch
code over to normal formatters.

Filter was wrong and sample was not being built on any boards. Exclude
platforms that do not support interrupt based UART drivers.

Due to a limitation on XCC, the inline assembly does not
produce the expected instructions. This results in a wrong
code sequence. On the other hand, plain C code works well.
The note about compilers seems to not be an issue on any of
our currently supported compilers.

The K_<thread option> flags/options avaialble to users were hidden in
the kernel private header files: move them to include/kernel.h to
publicize them.
Also, to avoid any future confusion, rename the k_thread.execution_flags
field to user_options.

The execution_flags will store the user-facing states of a thread.
This also fixes a bug where K_ESSENTIAL was already assigned to
execution_flags via the options field of
k_thread_spawn()/K_THREAD_DEFINE().

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.

added _MOVE_INSTR for RISCV32 architecture
The store instruction has a different syntax in RISC-V,
compared to the other architectures. Hence, for each
architecture, specify the entire load instruction within
the _MOVE_INSTR variable.

The main, idle, interrupt and workqueue call stack definitions are not available
to applications to call stack_analyze() on, but they often require to be
measured empirically to tune their sizes in particular applications and
use cases.
This exposes a new k_call_stacks_analyze() API call that allows the
application to measure the used call stack space for the 4
kernel-defined call stacks.
Additionally for the ARC architecture the FIRQ stack is also profiled.

Some thread fields were 32-bit wide, when they are not even close to
using that full range of values. They are instead changed to 8-bit fields.
- prio can fit in one byte, limiting the priorities range to -128 to 127
- recursive scheduler locking can be limited to 255; a rollover results
most probably from a logic error
- flags are split into execution flags and thread states; 8 bits is
enough for each of them currently, with at worst two states and four
flags to spare (on x86, on other archs, there are six flags to spare)
Doing this saves 8 bytes per stack. It also sets up an incoming
enhancement when checking if the current thread is preemptible on
interrupt exit.
