Yong Cong Sin bbe5e1e6eb build: namespace the generated headers with `zephyr/`
Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.

Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.

Updated the includes path of in-tree sources accordingly.

Most of the changes here are scripted, check the PR for more
info.

Peter Bigot f69a38162a kernel: atomic: consistently use named type for atomic pointer values
There's a typedef for non-pointer values compatible with atomic
non-pointer objects.  Add a similar typedef for pointer values, and
the corresponding macro for initializing atomic pointer types.

This also will simplify replacing the Zephyr atomic API with one
based on C11 atomics, should that be desirable.  C11 atomic pointer
values are not void*.

Andy Ross 0dd83b8c2e kernel: Add k_heap synchronized memory allocator
This adds a k_heap data structure, a synchronized wrapper around a
sys_heap memory allocator.  As of this patch, it is an alternative
implementation to k_mem_pool() with somewhat better efficiency and
performance and more conventional (and convenient) behavior.

Note that commit involves some header motion to break dependencies.
The declaration for struct k_spinlock moves to kernel_structs.h, and a
bunch of includes were trimmed.

Andy Ross 346cce31d8 kernel: Port remaining buildable syscalls to new API
These calls are buildable on common sanitycheck platforms, but are not
invoked at runtime in any tests accessible to CI.  The changes are
mostly mechanical, so the risk is low, but this commit is separated
from the main API change to allow for more careful review.

Andrew Boie b3eb510f5c kernel: fix atomic ops in user mode on some arches
Most CPUs have instructions like LOCK, LDREX/STREX, etc which
allows for atomic operations without locking interrupts that
can be invoked from user mode without complication. They typically
use compiler builtin atomic operations, or custom assembly
to implement them.

However, some CPUs may lack these kinds of instructions, such
as Cortex-M0 or some ARC. They use these C-based atomic
operation implementations instead. Unfortunately these require
grabbing a spinlock to ensure proper concurrency with other
threads and ISRs. Hence, they will trigger an exception when
called from user mode.

For these platforms, which support user mode but not atomic
operation instructions, the atomic API has been exposed as
system calls.

Some of the implementations in atomic_c.c which can be instead
expressed in terms of other atomic operations have been removed.

The kernel test of atomic operations now runs in user mode to
prove that this works.

Andy Ross 32a29d2805 kernel/atomic_c: Spinlockify
Mostly useless patch.  All architectures have their own code for
atomic operations and don't use this fallback.  Still, it's a trivial
locking setup and we might as well.

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.
