David Brown e2acfaede5 sim: Add explicit copyright and licenses to the sim
Add an apache SPDX header and explicit license lines.  The date ranges
of the license lines is derived from the git history.  Having these
explicitly present will make contributions from other parties easier, as
they will simply be able to add their own copyright line, rather than
having to describe that it only covers modifications.

David Brown e4576b888c sim: Test variants of single upgrade with multi-image
Test the variations of the situation where we are built for multi-image,
but are only upgrading a single image, including no dependencies,
correct dependencies, and unmet dependencies.

David Brown 18d301f588 sim: Add additional tests for mismatched upgrades
Test the configuration where one image has its dependencies met and the
other does not, and make sure in these cases we just hold back from
upgrading entirely.

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.

David Brown c3898d6168 sim: Add dependency tests to simulator
Create a trait `Depender` which is passed down to the image create and
verification to check and test for various types of dependency
resolution.  Add a test that uses this to test the simple case of unmet
dependencies preventing an upgrade.

The actual test is disabled (with an `if false ...`) because the code
under test loops forever in this configuration.

David Brown eebf502277 sim: Allow arguments to test entrypoints
Instead of a growing number of no-argument methods that just call other
methods with fixed arguments, change the `sim_test` macro to pass
through arguments to the test methods.  This will make it easier to
further parameterize the test entrypoints.

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.

David Brown e513324722 sim: Make `Run` into a proper builder
Rename `Run` to `ImagesBuilder`, and move its definition into the
`images` module.  This makes much more of the functionality local to
this module.  With this locality, all of the fields of `Images` can now
be made private making it easier to add future support for multiple
images.

David Vincze 2d736ad4c5 Replace flash partitioning terminology
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.

David Brown a4167efc8e sim: Create cargo tests for each testcase
Now that the test infrastructure has changed so that the tests can be
run independently, create a series of cargo tests that run them.  This
allows the tests to simply be run as:

    cargo test

or possibly with feature flags

    cargo test --features overwrite-only

It is also possible to run individual tests by giving their name after
the "cargo test" command.

As a start of doing the testing using Rust/Cargo's test framework, write

now, except that there is an assertion that there were no failures.
