[PATCH 0/4] Python refactoring

[Harald Seiler <hws@denx.de>]

This series contains a number of improvements to python code in isar:

* All instancess of subprocess.{call,Popen,check_call}() have been changed to
  never use `shell=True`.  This will hopefully prevent bugs in the future.
* The use of the % formatter was replaced by other methods, as % was deprecated
  because it can behave weirdly.  Unfortunately, as we have to support python
  back to 3.5, we can not yet make use of f-Strings, so other options had to be
  used.  I decided to use string concatenation for simple cases where the use
  of .format() would have been too verbose.
* A recursive call in get_image_name was removed in favor of an imperative code
  style.  This should make the respective function easier to read.

Harald Seiler (4):
  Remove all uses of subprocess.call(shell=True)
  Use modern python formatting
  image: Remove recursion in get_image_name
  wic: Refactor fakeroot script
