mage creation improvements

Hi,

This patchset contains various improvements for the image creation functionality made by Patchick Ohly during his work on bug #9076:
- renamed COMPRESSION variables to CONVERSION as the term "compression" is no longer accurate
- support converting masked types

Changes in v2: rebased on top of master-next
returned image_getdepends back to image_types.bbclass
Changes in v3: rebased on top of recent master
Changes in v4: rebased on top of recent master
Changes in v5: removed 2 problematic patches

The following changes since commit 5b61fa04a335a4fdefd435dc25d4bac41ee21e39:

bitbake: toaster-tests: fix URL given for Chromedriver download (2016-07-29 09:53:32 +0100)
