Rename any instance of scene layer or render layer in code with view layer

The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.

* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started

Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.

Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.
