[totem/wip/hadess/bug-fixes: 1/4] backend: Put stream buffers in a separate directory

[Bastien Nocera <hadess src gnome org>]

commit a46aa611101191f1de7338f19f7c9bbb32180519
Author: Bastien Nocera <hadess hadess net>
Date:   Thu Feb 7 18:06:02 2019 +0100

    backend: Put stream buffers in a separate directory
    
    So that they're not dropped directly in the bare ~/.cache/ directory.
    Those temporary files will now be in ~/.cache/totem/stream-buffer.
    
    Closes: #230
