From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

This allows the user to add scripts[1] to the swu file by
setting the variable `SWU_SCRIPTS`. Scripts can be used to
prepare the system for an update.

```
SWU_SCRIPTS = "<script_file_name>@<script_type>@<optional_data>"
```
This will add  `file://<script_file_name>` to the variable `SRC_URI` and
`<script_file_name>` to `SWU_ADDTIONAL_FILES`. The sw-description will contain
the following section:
```
    scripts: (
        {
          filename = "<script_file_name>";
          type = "<script_type>";
          data = "<optional_data>";
          sha256 = "<sha256 of postinstall.sh>";
        },):
```

Changes v2:
 - change seperator from `:` to `@` as it already used for the
   configfilecheck
 - add optional data entry
 - add warning if less then 2 parameters are given for entry

---------------------------------^
shouldn't that be sha256 of <script_file_name> ?

How about the lua scripts, where the preinst / postinst are just
functions within a single script? Could you please also give an example
regarding how to specify that.

This would be

```
SWU_SCRIPTS = "installscript.lua@lua@some_data"
```

and the installscript contains:

```
function preinst()

end

function postinst()

end
```	

I can add the script to `recipes-core/images/swu/` if this helps, but 
currently we have no functionality in cip-core.
