* Adds a new level (BOOT_LOG_SIM) to be used only for messages that
are interesting while debugging bootutil in the simulator. This should
be used for extra verbose prints.
* Also added fflushs after fprints to guarantee that messages are printed
even when assertions are raised.
* For abstraction completeness, add "do nothing" definitions of _LOG_SIM
to the other ports.
* Make DEBUG the default level when building the simulator (one can
still lower verbosity using any other value for RUST_LOG).

Add Mynewt option to enable building a bootloader that uses an
alternative swap algorithm, that first moves up all sectors in slot1 and
then directly swaps between slot0 and slot1.

Allow Mynewt to be used in multi-image builds. Primary and secondary
slots of image 1 are hard-coded to FLASH_AREA_IMAGE_2 and FLASH_AREA_IMAGE_3.

For Mynewt, if a watchdog driver is available, it is always used and feed
during a swap operation. Since the swap operation is able to resist resets,
the watchdog can stay disabled to preserve some flash space (watchdog
driver), with the side-effect that a swap might take longer because of
having to resume interrupted operations.

When HW / OS provides an always enabled watchdog, this macro can
optionally be implemented to avoid resets which are expected to
occur under normal conditions when swapping very large images or
running on slower devices.

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.

The old log subsystem has been deprecated in Zephyr.
Migrate to the new subsystem to avoid compilation warnings.
In-place log processing is selected as it is required as MCUBoot is
one thread application.

This adds a new option that allows copying slot0, from the contents
of slot1, if slot0 is found out to be erased and not validated, and
the contents of slot1 are validated.
This mechanism basically enables a device to "bootstrap" from the
contents of an external flash that has a valid image, given that the
only flashed thing in the internal flash is the bootloader.

Take the opportunity to clean up a bit of platform cruft that has
gotten into bootutil by moving it to mcuboot_config.h, and ensuring it
is documented in the template config file.

This still defaults to 128 for compatibility, but allows users to
specify less elements to save space, or more elements for devices that
have massive flash size and/or too small sectors.

This add a new option to overwrite-only mode that enables copy/erase of
only the amount of sectors that are required to store the source image.
This is enabled by default when overwrite-only mode is used.

This removes the dependency on tinycrypt lib provided by mynewt and
switches to the one bundled in mcuboot. Also fixes a bug where tc
was only being used when eliptic curve 256 was selected as sign
algorithm.

Since we are changing the image header format, there is no reason to
continue to support the old PKCS#1 v1.5 signatures. Remove the
definitions, and conditional complication related to this, and only
support the newer PSS signatures.

This enables mynewt to use mcuboot as a remote repository, which is only
required when using newtmgr to manage images. Since mcuboot has slightly
changed the trailer format, newtmgr built against the bundled mynewt
bootloader writes the magic and flags to the wrong location.
To build a mynewt app the wants to run with mcuboot as the bootloader
and requires newtmgr one needs to change the app's pkg.yml dependencies
as follows:
- - boot/bootutil
+ - "@mcuboot/boot/bootutil"
