Merge branch 'master' into blender2.8

Please **DO NOT** add changes from master when it's totally uneeded!

Changes to BLI_ area most certainly shall *always* be done in master,
there is absolutely no point in adding more diff between the two
branches than needed, will only makes merging more cumbersome!
