513e6ed5d2 arch/common: Mark interrupt tables const when !DYNAMIC_INTERRUPTS
When not using dynamic interrupt mapping, various interrupt tables are
configured to be stored in read-only memory in the linker script.. Mark
them const so that the linker doesn't complain.

This affects _sw_isr_table, _irq_vector_table, and z_shared_sw_isr_table in
arch/common along with _VectorTable in arch/arc.

d76cf5b57e arch: mips: Rename _Fault to z_mips_fault
The exception fault handler function is named _Fault which is inconsistent
with all other arch-specific functions present in Zephyr. This patch
replaces the name with z_mips_fault.

909ff45f0c kernel: arch: move arch_swap() declaration
Moves the arch_swap() declaration out of kernel_arch_interface.h
and into the various architectures' kernel_arch_func.h. This
permits the arch_swap() to be inlined on ARM, but extern'd on
the other architectures that still implement arch_swap().

Inlining this function on ARM has shown at least a +5% performance
boost according to the thread_metric benchmark on the disco_l475_iot1
board.

7e225efab7 arch: initialize irq_offload during boot, do not use SYS_INIT

custom arch_cpu_idle and arch_cpu_atomic_idle implementation was done

symbols, xtensa used a kconfig and all other architectures did not
really care, but this was a global kconfig that should apply to all
architectures.

e54b27b967 arch: define struct arch_esf and deprecate z_arch_esf_t
Make `struct arch_esf` compulsory for all architectures by
declaring it in the `arch_interface.h` header.

After this commit, the named struct `z_arch_esf_t` is only used
internally to generate offsets, and is slated to be removed
from the `arch_interface.h` header in the future.

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.

9eeb78d86d COVERAGE: Fix COVERAGE_GCOV dependencies
CONFIG_COVERAGE has been incorrectly used to
change other kconfig options (stack sizes, etc)
code defaults, as well as some samples behaviour,
which should not have dependend on it.

Instead those should have depended on COVERAGE_GCOV,
which, being the one which adds special code and
temporary RAM storage for embedded targets,
require changes to many features.

When building for the native targets, all this was
unnecessary.

=> Fix the dependency.
