This patch introduces the direct execute-in-place (XIP) mode in addition
to the other upgrade modes (swap strategies, overwrite-only). When
direct-XIP is enabled with the MCUBOOT_DIRECT_XIP option, mcuboot
selects the newest valid image based on the image version numbers from
the image header, thereafter the selected image runs directly from its
flash partition (slot) instead of moving it. Therefore the images must
be linked to be executed from the given image slot. It means that in
direct-XIP mode either of the primary and the secondary slots can hold
the active image.
This patch is based on the NO_SWAP upgrade strategy which was first
introduced in the Trusted Firmware-M project.
Source TF-M version: TF-Mv1.0.

This commit is a followup to the usage of `find_package(Zephyr ...)`.
The zephyr/hello-world sample has been updated to use find_package.
The assemble.py script now takes ZEPHYR_BASE as an argument, so it may
be used from CMakeLists.txt files when ZEPHYR_BASE is not set in
environment, and thus the Makefile sample has been adjusted accordingly.

Remove a redundant chip erase from run-tests.go. The '-e chip' should
tell pyocd to perform a chip erase. There seem to be some combinations
of daplink and pyocd that if an invalid image is loaded into the device,
it can no longer be flashed by pyocd. Performing the chip erase as a
separate command easily gets it into this state. It can be recovered by
using the DAP filesystem to write the image.

Zephyr builds use 'cmake' which can generate either makefiles, or use
the Ninja build tools. There are several significant advantages to
using Ninja as the build tool:
- It is significantly faster. Ninja reads a directory and stats the
files in it once. Make often stats a given directory thousands of
times, many for files that don't even exist.
- It has better output. Ninja collects commands together with their
error output. When doing multi-cpu builds, Ninja prints a status
indicator, and only prints fully verbose commands when that command
fails. Instead of having to try an piece together a given command
with its errors, they will always be together.
- Make's support of multiple CPUs is a crude hack. Make forks off
multiple processes to use multiple CPUs. These processes don't
communicate with each other (very much), which causes make to often
continue after enountering errors. It is common for a multi-CPU
make invocation to print hundreds or thousands of additional lines
after an error message.
Nearly all distros have a version of Ninja available in their package
manager, making this change of low cost.

This patch introduces the BOOT_IMAGE_NUMBER macro and current_image
variable to support multiple updatable images and the associated
extended flash layout.
The FLASH_AREA_IMAGE_* object-like macros are replaced with
function-like ones and therefore some functions have been updated,
because the labels of a switch statement and the initialization
values of objects with static storage duration have to be constant
expressions.

This change replaces the slot 0/1 terminology with primary/secondary
slot and replaces FLASH_AREA_IMAGE_0/1 with
FLASH_AREA_IMAGE_PRIMARY/SECONDARY. This naming convention may be more
understandable, fits better to MCUs with multiple images and it is an
architecture agnostic alternative as well.

pyocd 0.14.0 merged its command-line tools into a unified pyocd tool
with subcommands. The separate command-line tools still remain, but are
deprecated. Update all pyocd calls in samples and documentation to use
the new unified pyocd tool with subcommands.
Note that pyocd 0.15.0 has an issue with the command 'pyocd erase',
which was fixed in pyocd 0.16.0.

The `--included-header` was "mandatory" when using imgtool with firmware
images generated by the Zephyr build system and it was a source of
issues when it was forgotten. This removes `--included-header` and adds
a new parameter `--pad-header` with inverted semantics, to be used only
when a zeroed header is required to be added to the firmware image.

Continue removing platform-specific conditional compilation from
bootutil by adding a new MCUBOOT_HAVE_ASSERT_H configuration option
and associated header file. Right now, that's only used by the
simulator.
That leaves just bootutil_log.h with platform-specific contents, but
since it's meant to be an abstraction layer for logging, we'll let it
stand for now.

Handle the CONFIG_BOOT_SIGNATURE_TYPE_xxx values in Zephyr's
mcuboot_config.h by converting them into the platform-agnostic MCUboot
definitions.
This requires some changes to the way the release test Makefile is
structured, since Kconfig symbols cannot be set from the command line.
Instead, use the OVERLAY_CONFIG feature of the Zephyr build system,
which allows specifying extra fragments to merge into the final
.config. (This is an orthogonal mechanism to setting CONF_FILE; it is
used by Zephyr's CI script sanitycheck to add additional fragments, so
it's appropriate for use by MCUboot's testing scripts as well.)
We additionally need to move to a single prj.conf file due to a
dependency issue. We can no longer determine CONF_FILE from the
signature type, since that is now determined from the final .config or
autoconf.h, which is a build output that depends on CONF_FILE.
To move to a single prj.conf:
- delete prj-p256.conf and adjust prj.conf to serve both signature types
- add a top-level mbedTLS configuration file which dispatches to
the right sub-header depending on the key type
- as a side effect, have the simulator pick the right config file
depending on the case
This fixes and cleans up quite a bit of the signature type handling,
which had become something of a mess over time. For example, it fixes
a bug in ECDSA mode's configuration that wasn't actually selecting
config-asn1.h, and forces the simulator to use the same mbedTLS
configuration file as builds for real hardware.
Finally, we also have to move the mbedTLS vs. TinyCrypt choice into
mcuboot_config.h at the same time as well, since CMakeLists.txt was
making that decision based on the signature type.

Mynewt uses this file to convert MYNEWT_VAL(xxx) to MCUBOOT_xxx config
options. Zephyr currently adds config options via the compiler command
line, but it should use this instead.
As prep work for that conversion, add an empty mcuboot_config.h to the
Zephyr port, and include this file unconditionally wherever it's
needed. This takes care of the simulator as well, since that puts
boot/zephyr/include on its C file include path.
This turned up a couple of files (bootutil_priv.h and caps.c) that
were using the MCUBOOT_xxx config values without including the
file. Add the includes there, as they'll be needed later.
To make this official, add it to the requirements in the porting guide
and provide a template file porters can use while getting started.
