67ca176754 headers: Fix headers across the project
Any word started with underscore followed by and uppercase letter or a
second underscore is a reserved word according with C99.

5f67a6119d include: improve compatibility with C++ apps.
This patch lets a C++ application use more of Zephyr by adding guards
and changeing some constructs to the C++11 equivalent.

Changes include:

- Adding guards
- Switching to static_assert
- Switching to a template for ARRAY_SIZE as g++ doesn't have the
  builtin.
- Re-ordering designated initialisers to match the struct field order
  as G++ only supports simple designated initialisers.

3aa347fa49 misc/byteorder: add support for __bswap_64
We currently support converting from cpu format to BE for
u16_t and u32_t.  Let's add u64_t as well.

NOTE: This will be used in LWM2M subsys later.

cc334c7273 Convert remaining code to using newly introduced integer sized types
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.

789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

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.

f72dcf595c byteorder: Add buffer swap helpers
Two functions are proposed:
- sys_memcpy_swap(): will memcpy and swap the 2 given buffers
- sys_mem_swap(): will swap the buffer in place.

The idea is to propose 2 different functions optimized for 2 different
usage.

It's an important header, used in many place and it's thus very easy to
get different sub-system loading it thus leading to redefinition error.
