We want a high-level FS abstraction to access UEFI volumes based on the (Simple)FileSystemProtocol. This is a large portion of work and split into multiple tasks/PRs tracked in this issue:

• initial fs module - Introducing a high-level FS abstraction #472
  • minimal public API (just errors and fs functions but no path abstraction)
  • users use &str as path type
  • module API close to std::fs
  • integration test
• discuss and implement a nice Path abstraction - uefi/fs: add path and pathbuf abstraction #771
  • will there be Path and PathBuf?
  • users should pass a &str as well as PathType to all functions
    -> param is something like: Into<PathType>
  • what will be part of public API?
• implement fs::remove_dir_all method that is missing in the initial merge request - fs: implement remove_dir_all #799
• check public API again after all of the above was merged (before the first release containing the new functionality)
• check the integration test again: are all corner-cases and valid use-cases covered?
