From: Bartosz Golaszewski <bgolaszew...@baylibre.com>
Make each IMAGE_CMD task an sstate task with its own IMGDEPLOYDIR
override. This way each generated set of artifacts is deployed as soon
as it's ready instead of the do_image_complete task handling the entire
deployement. This allows us to better fine-tune dependencies e.g. we
can make do_image_wic depend on fitImage task which can in turn depend
on do_image_ext4.
We need delete the IMGDEPLOYDIR variable from the data object passed
to each image task so that it gets expanded with the correct override.
In order to make sure that tasks added to SSTATETASKS in anonymous python
functions are correctly setup, move the code that assigns pre- and
postfuncs to an event handler invoked on bb.event.RecipeTaskPreProcess
in sstate.bbclass. This event is fired right after the anonymous
functions.

Changes since v2:
- dropped the qemuboot patch (already upstream)
- switched to % string formatting instead of using .format() for consistency
