To avoid making a system call for every character emitted, there is now
a small line buffer if userspace is enabled. The interface to the kernel
is a new system call which takes a sized buffer of console data.
If userspace is not enabled this works like before.

This is unmaintained and currently has no known users. It was
added to support a Wind River project. If in the future we need it
again, we should re-introduce it with an exception-based mechanism
for catching out-of-bounds memory queries from the debugger.
The mem_safe subsystem is also removed, it is only used by the
GDB server. If its functionality is needed in the future, it
shoudl be replaced with an exception-based mechanism.
The _image_{ram, rom, text}_{start, end} linker variables have
been left in place, they will be re-purposed and expanded to
support memory protection.

This places a sentinel value at the lowest 4 bytes of a stack
memory region and checks it at various intervals, including when
servicing interrupts or context switching.
This is implemented on all arches except ARC, which supports stack
bounds checking directly in hardware.

This should fix the grouping for debugging options appearing in the
main "menuconfig" menu.

CONFIG_DEBUG_INFO was disabled for IAMCU targets. As per Jira update forked
arch/code is gone. So it should not block enabling DEBUG_INFO for IAMCU.
Currently CONFIG_DEBUG_INFO depends on (x86 = y && !X86_IAMCU)
CONFIG_DEBUG_INFO can not be set for IAMCU. this patch removes dependency.

In order for OpenOCD to have a high-level view of an RTOS, it uses the
GDB protocol to obtain symbols from the system.
The GDB protocol, however, does not allow obtaining fields from
structures directly, and hardcoding offsets is not only brittle (due to
possibly different architectures or changes in the code), it's also
infeasible considering Zephyr is highly-configurable and parts of key
structs can be compiled in or out.
Export an array with offsets for these key structs. Also add a version
element in that array to allow changes in those structs.

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.
