This extends the simulator to be able to test the bootloader in devices
which use flash technologies that erase flash at 0 instead of 0xff.
Two MCU devices that have this "property" are the STM32L0x and STM32L1x
lines from ST.

These (currently) trivial files do not add license headers. Go ahead
and add the boilerplate Apache header.
In addition, I've also added an SPDX header. Although this is a first
for the MCUboot project, this will provide a template for adding these
headers to other files.

The patch introduce usage of zephyr flas_map module instead
of mcuboot zephyr-only implementation. Unused flash_area_to_sectors
API of former flash_map was removed as well.
Size of sector-status-update-map entry is now defined thanks to the
minimum write size supported by the flash driver.
For avoid ambiguity former zephyr-only files flash_map.c
were renamed to flash_map_extended.c (its code now implements
only addition to this what zephyr flash_map implements).
flash_map.h header include is now warped by flash_map_backedn.h headre
because implementations and include pathes are diferent in Zephyr and Mynewt.
Usage of hal_flash_align() were replaced by usage flash_area_align().
This provide consistency between MyNewt and Zephyr implementation as
this API is available in both RTOSes.
flash_map.h was moved to the simulator c-support files as now missing in
the boot/zephyr subdirectories.
f. boot_scratch_fa_device_id was removed as unused.
f. boot_img_fa_device_id was and expanded the only use of it
(on loader.c).

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.

Take the opportunity to clean up a bit of platform cruft that has

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.

Assertions that are expected to fail under sim test, are now marked as such
using the macro ASSERT which allows to programmatically switch between normal
assert() behavior and captured assertion.
Assertion changes were moved to more appropriate owners and code duplication
was removed.

When building in simulator mode, mock assert() to call an simulator
function which will enable other code to check if some path failed.
The assert checking interface, was added to boot_go which now
returns the low-level invocation results as well as the number of
asserts triggered.
Some new added tests check for assert() and expect it to happen. To not
abort tests, assert() was changed under sim env to not call c assert()
and instead just do some internal calculation which could be checked
by the simulator after a bootloader run and assert() catching behavior
was made optional (each test choses the behavior it needs).
