David Brown fe5ab1c35b sim: Generalize test image dumping
Decode the MCUBOOT_DEBUG_DUMP environment variable into a series of
comma-separated strings, and create debug dumps for any test that
matches one of these strings.  Also, the special string 'all' will match
every test, causing every image under test to be dumped.

The dumped images will contain an atomic counter, so that all of the
generated files will be unique for a given run.

David Brown 297029ab72 sim: Add debugging ptable to image dumps
Add a `debug_dump()` method to `Images` to allow the images to be
written to a file.  The dependency test will call this if the
environment variable MCUBOOT_DEBUG_DUMP is set.

In order to make these debug dumps more useful, add a simple partition
table to the beginning of the image (where MCUboot would reside on
target).  This has a simple header, and then entries for each partition,
using the partition ids used within the simulator.  This allows the
image to be more easily used by external tools.

As an example, `scripts/mcubin.bt` is a binary template for the [010
Editor](https://www.sweetscape.com/010editor/), allowing it to decode
and show the details of images from MCUboot.

Fabio Utzig 8000e325f1 Remove global test thread locking
With the recent changes in bootutil, now there is no need to lock the
test threads to run sequentially, so the global lock was removed. The
locking now happens to access resources such as flash, flash params,
simulator context, etc on a per thread basis. Some of the global
variables that were used by the simulator itself (FFI) were made into a
context struct passed in to invoke_go.

Fabio Utzig b0f0473352 Remove current_image global and macro updates
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.

David Brown f9aec954e3 sim: Simplify verification methods
There are three methods that verify multiple images that essentially
manually implement the `all` and `any` methods of `Iterator`.  It makes
it difficult to understand what these do, as there is an early return of
true or false, with various negations of the check.

Replace these with calls directly to `any` or `all` so that it is
clearer what each function is doing.  The generated code should be the
same.

Fabio Utzig ed4a53635a Fix test/revert upgrade flash count
When doing a test with fails, the total number of flash accesses is
first calculated doing an upgrade without fails, which is then used to
fail/resume at all test points. The count was always considering the
setting of a permanent upgrade, which added 1 to the total count in a
non-permanent upgrade. This amount was being discounted when running
the test/revert with fails, although the discount was only ok for single
images. This adds a new image constructor that does not run a permanent
upgrade and thus gets the correct number of flash accesses for a
test/revert no matter how many images are being tested.

Christopher Collins a1c1204f65 Fix double swap on interrupted revert
This fixes #480.

When mcuboot rewrites image trailers during a swap, some information is
lost.  If a reset occurs before the swap completes, mcuboot may not be
able to determine what which swap type to resume upon startup.
Specifically, if a "revert" swap gets interupted, mcuboot will perform
an extraneous swap on the subsequent boot.  See
https://github.com/JuulLabs-OSS/mcuboot/issues/480 for details.

This commit adds an additional field to the image trailer: `swap-type`.
The new trailer structure is illustrated below:

```
     0                   1                   2                   3

```

The `swap-type` field contains one of the `BOOT_SWAP_TYPE_[...]` constants.
Every time a trailer is written, this field is written along with it.
When resuming an interrupted swap, mcuboot uses this field alone to
determine the type of swap being resumed. For new swap operations
(non-resume case), this field is not read at all; instead, mcuboot
consults the `boot_swap_tables` array to determine the swap operation to
perform (as it did prior to this commit).

Some additional changes were necessary to make all the simulated unit
tests pass:

* Before initiating a new swap operation, always write the image trailer
to the scratch area.  This step allows mcuboot to persist the
`swap-type` field somewhere before erasing the trailer in the primary
slot.  If a reset occurs immediately after the erase, mcuboot recovers
by using the trailer in the scratch area.

* Related to the above: if the scratch area is being used to hold status
bytes (because there are no spare sectors in the primary slot), erase
the scratch area immediately after the trailer gets written to the
primary slot.  This eliminates ambiguity regarding the location of the
current trailer in case a reset occurs shortly afterwards.

Christopher Collins 2adef70e33 Use same format for scratch and slot trailer
Prior to this change, the scratch image trailer had a different format
from a slot image trailer.  Specifically:

1. The scratch trailer only contained a single set of status entries
   (three bytes); the slot trailer contained `BOOT_STATUS_MAX_ENTRIES`
   sets of status entries.

2. The scratch trailer did not contain the `copy_done` field.

This inconsistency required some extra conditional logic in the trailer
handling code.  It is simpler to just use the same trailer format
everywhere.

This commit removes this inconsistency.  Now, the scratch trailer
structure is identical to that of the slot trailer.

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

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.

Marti Bolivar a4818a5565 zephyr: migrate signature type to Kconfig
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.
