29b2bda786 wic: extend empty plugin with options to write zeros to partiton
Adds features to explicitly write zeros to the start of the
partition. This is useful to overwrite old content like
filesystem signatures which may be re-recognized otherwise.

The new features can be enabled with
'--soucreparams="[fill|size=<N>[S|s|K|k|M|G]][,][bs=<N>[S|s|K|k|M|G]]"'
Conflicting or missing options throw errors.

The features are:
- fill
  Fill the entire partition with zeros. Requires '--fixed-size' option
  to be set.
- size=<N>[S|s|K|k|M|G]
  Set the first N bytes of the partition to zero. Default unit is 'K'.
- bs=<N>[S|s|K|k|M|G]
  Write at most N bytes at a time during source file creation.
  Defaults to '1M'. Default unit is 'K'.

7350e82ce1 scripts: Add copyright statements to files without one
Where there isn't a copyright statement, add one to make it explicit.
Also drop editor config lines where they were present and add license
identifiers as MIT if there isn't one.

75b74f6b8d wic: Introduce empty plugin to create unformatted empty partitions
The empty wic plugin is used to create unformatted empty partitions for wic
images.

To use it you must pass "empty" as argument for the "--source" parameter in
the wks file. For example:
    part foo --source empty --ondisk sda --size="1024" --align 1024

Also adds a selftest for this plugin where the 'Fstype' column from 'wic
ls' should be empty for the second partition as listed in
test_empty_plugin.wks.
