Autoversion tries to get the name of packages from the list of files for
the CPIO archive, while the list of packages is already set in the
SWUPDATE_IMAGES variable.

Versions of the packages included in update file needs to be entered
manually in sw-description file or provided in as a bitbake variable.

This patch searches for a group in sw-description file containing the
tag `version = "@SWU_AUTO_VERSION"`.
If found, the version of the corresponding package is fetched from it's
package-data-file (`PV`) and the tag is replaced with the version.
Possible trailing strings in `PV` starting with `+` (e.g.
"+gitAUTOINC+...") are dropped to keep semantic versions.

Since the filenames not always belong to the package name (deployed
with another name or the file is a container for the real package)
support providing the correct package name by appending the tag with
`:<package-name>`.

In release 2019.11, support for the salt encryption parameter was removed (see commit 9ce94342d3c212b06a283f95dc9c1c8c52155ce7).
Consequently, remove all references to a salt value for key creation and encryption.
The keyfile for encryption can still contain a salt value, it will simply be ignored.
Also remove obsolete cmd variable.

If sw-description is encrypted and signed, swupdate verifies the decrypted sw-description file (see core/stream_interface.c in swupdate code).
So the signature has to be created from the unencrypted sw-description as well.
Alternatively, the swupdate code needs to be changed to verify the encrypted sw-description.

Commit introduces the encryption into the swupdate class, but it breaks
builds if encryption is not used at all. Fix this and rework function
to retrieve key from a file.

Replace os.system() with subprocess.run() - this should be done for other
occurrencies od os.system() that is declared obsolete.

Variables are just matched one for each line in sw-description. The
patch extend the behavior and searches recursively in each line for all
matches of the substituion pattern @@variable@@.

This adds supports for variable's flags, too. The following match is
also resolved:

	@@variable[name-of-flag]@@

This is useful to evaluate SWUpdate's flags as the image extension.

Even if the current check remind that a variable is maybe missing, there
are use cases where it is useful to replace an empty variable.
