Currently we are converting dir_info to/from lists all the time. The reason is that dir_info is stored as list of dicts in *.dir files, but that makes it hard to work with. In addition to that, we will likely be changing .dir file format in the near future #829, so we need to abstract away dir_info into something that we won't care how it will be stored on disk.
