Refactor low-level blendfile reading into separate files
Instead of handling mmap, compression etc. all directly in readfile.c, refactor
the code to use a generic FileReader.
This makes it easier to add new compression methods or similar, and allows to
reuse the logic in other places (e.g. thumbnail reading).
