A previous change was added to allow the `getpriv` command to dump ec256
keys in both openssl and pkcs8. That PR did not touch other key file
types which resulted in errors using that command with RSA, X25519, etc.
This commit generalizes the passing of the `format` parameter, so each
key type can decide which format it allows a dump to be produced in,
and what default to use.

`--vector-to-sign` only exports the image payload, or digest, to be
signed externally; it doesn't require any keys to be provided. This
commit moves the code outside a key required block, after the payload
and digest were already calculated from "image + headers + protected
TLVs".

Fix the remaining PEP8 warnings that appear on image.py, ecdsa.py
or main.py for imgtool.

This patch improves the existing ECDSA key generation feature
in the imgtool by:
- Fix a bug in the 'minimal' representation of PKCS#8 keys where
the resulting ASN.1 DER encoding is not compliant
- Add the option to export ECDSA private keys in SEC1 format by
providing a command line option -f or --format that can be
'openssl' (for SEC1 format) or 'pkcs8'. This format ends up in
key encodings which are generally smaller than PKCS#8.

Common prints such as the one that happens when an image is signed
are clearer if the source of print is added (i.e. filename), especially
for those build integration flows where imgtool is invoked as part of
a set of operations.

Update a previous PR were PEM exporting was added to the `--lang`
parameter, even though PEM is not a source code language per se.
This PR adds `--encoding/-e` to `getpub` command, for exporting
in formats other than a language source code. `--lang` is left with
a deprecation message, so it could be removed in a future version.
The default behavior of exporting source code in C was preserved.

Update `getpub` with new `lang` option, "pem", which allows exporting a

When generating an image with trailer (--pad or --confirm), the
imgtool also adds the erased values into that area. This is not
wanted for flash drivers which use ECC and treat writing erased
values as a real write action, which cannot be overwritten anymore.

The value of `--max-align` parameter passed to imgtool can never be
less than the value of `--align` parameter. At present the default
value of `--max-align` is fixed at 8. This forces user to pass the
parameter even when its value can be safely inferred.
Change the default value of the `--max-align` parameter to the larger
of the two values: `--align` or 8. Consequently, the user is required
to pass the parameter only if the flash alignment of the primary and
secondary slot differ.

As the APIs are identical, we can import cbor2 and if that fails fall

This patch introduces the ram-load mode in addition to the other
upgrade modes (swap strategies, overwrite-only, direct-XIP). When
ram-load is enabled with the MCUBOOT_RAM_LOAD option, mcuboot
selects the newest valid image based on the image version numbers from
the image header, thereafter the selected image loaded to the RAM and
executed from there. Load address is extracted from the image header.
Therefore the images must be linked to the RAM memory region.
The ram-load mode is very similar to the direct-XIP mode, main
difference is to load the newest image to the RAM beforehand the
authentication and execution. Similar to direct-XIP mode either
of the primary and the secondary slots can hold the active image.
Ram-load can be useful in case of a bit more powerful SoC, which
is not constrained in terms of internal RAM. It could be that image
is stored in external and therefore untrusted flash. Loading image
to internal (trusted) RAM is essential from the security point
of view the system. Furthermore execution from internal RAM is much
faster than from external flash.
This patch is based on the RAM_LOADING upgrade strategy which was
first introduced in the Trusted Firmware-M project.

This patch introduces the direct execute-in-place (XIP) mode in addition
to the other upgrade modes (swap strategies, overwrite-only). When
direct-XIP is enabled with the MCUBOOT_DIRECT_XIP option, mcuboot
selects the newest valid image based on the image version numbers from
the image header, thereafter the selected image runs directly from its
flash partition (slot) instead of moving it. Therefore the images must
be linked to be executed from the given image slot. It means that in
direct-XIP mode either of the primary and the secondary slots can hold
the active image.
This patch is based on the NO_SWAP upgrade strategy which was first
introduced in the Trusted Firmware-M project.
