Add basic flash_sector struct and offset calculation routines. This
fixes the build using swap move, because this data is required to
calculate the maximum image size.
Fixes#1567

The commit provides set of getter functions that allow to
access fields of flash_area and flash_sectors objects.
Usage of these function, instead of direct field access, allows
to keep common code intact when internal, system specific,
implementation changes.
The commit contains the implementation of getters for following
ports: cpress, mbed, mynewt, zephyr.

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.

The boot_serial test was failing build because it hadn't been updated to
use new multi-image flash area nomenclature. This fixes the build.

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.

The boot loader state currently exists as global variable (boot_data)
which is accessed by all routines; this updates all routines that
require access to the state to receive it by parameter.
Variables that are declared as "static" (globals) were #ifdef'ed to
only use static when building a native bootloader, to avoid stack
allocation. When bootutil is built to run in the simulator they are
stack allocated to avoid thread share.

Currently to determine which image is being operated on, there is a global
variable called current_image which is used by most macros and APIs to
correctly access the flash areas required by the bootloader. This moves
this variable to the already existing state struct and refactors all
macros and APIs to receive the current image by parameters. To maintain
compatibility some of the macros were not updated and use image 0 when
called.
The definitions of FLASH_AREA_IMAGE_PRIMARY and FLASH_AREA_IMAGE_SECONDARY
for Mynewt compatibility were moved out of bootutil sources to a Mynewt
specific include file.

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).
