Benjamin Walsh ed240f2796 kernel/arch: streamline thread user options
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.

David B. Kinder ac74d8b652 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.

Jira: ZEP-1457

Benjamin Walsh f955476559 kernel/arch: optimize memory use of some thread fields
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.

Anas Nashif 66cfcc26bc tests: introduce Makefile.test
To customise test builds and support test related features such as time
stamps and a boot banner, introduce a Makefile variant that is dedicated
to testing.

Initially we introduce a new config overlay that is used for all tests, in
this case we enable BOOT_BANNER and BUILD_TIMESTAMP. This will print the
current version and the date, useful when reporting bugs and also an
indicator that the system has booted before the test has started.

For example:

[QEMU] CPU: qemu32
***** BOOTING ZEPHYR OS v1.6.99 - BUILD: Dec 21 2016 19:57:13 *****
tc_start() - Test Nanokernel CPU and thread routines
Initializing nanokernel objects

Benjamin Walsh f6ca7de09c 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.

Allan Stephens dd07b4779f kernel: Eliminate use of KERNEL_V2 configuration option
The unified kernel is now the only supported kernel, so this
option is unnessary. Eliminating this option also enables
the removal of some legacy code that is no longer required.

Benjamin Walsh 8cf56bcac7 unified: dissociate system workqueue from common workqueue module
Making a reference to the common work queue code should not necessarily
drag in the system workqueue, since it is possible to use a workqueue
that is not the system workqueue. This is done by moving the system
workqueue into its own code module.

Moving the system workqueue to its own code module allows removing the
NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the
common workqueue code and system workqueue all the time. They are only
linked in the final image if a reference to them exist, same as the
other kernel modules.

Benjamin Walsh 5c2731f27f tests: for the system workq in for obj tracing tests
The test relies on the workq thread being in the system. It is possible
for the workq to not be in the system even if CONFIG_SYSTEM_WORKQUEUE is
enabled, if nothing makes references to the symbols in the object file,
so we cannot rely on the kconfig option to know if the system workq
thread is in the system or not. So, force it in.

Anas Nashif be4fe7f4e5 tests: move kernel tests to tests/legacy
Move all kernel tests using legacy APIs into tests/legacy to continue testing
old APIs and compatibility. We keep in tests/kernel those tests that do not use
any kernel APIs and generic in nature, those should not be affected by the
unified kernel API change.

In tests/kernel we will start adding tests that are unified kernel only. Later
and when deprecation period is over the legacy tests would be dropped.
