[pbs-devel] [PATCH v4 many] fix #4995: Include symlinks in zip file restore

[Filip Schauer]

Include symlinks when restoring files from a backup as a zip file.

Resulting ZIP files were successfully tested on Linux with: zipinfo,
unzip, unar

On Windows the extracted symlinks show up as regular files containing
the path to the destination. As far as I am aware Windows Explorer does
not support symlinks in ZIP files.

Changes since v3:
* Move content to Regular FileType enum
* Make ZipEntry private
* Add take_reader function to FileType enum

Changes since v2:
* Add a FileType enum and embed the symlink target into the enum.
* Add unit tests for ZipEncoder to the proxmox-compression crate

Changes since v1:
* Use P instead of &Path
* Fix compile error due to misplaced comma
* Check content before symlink_target, since regular files are more
  common than symlinks

proxmox:

Filip Schauer (3):
  compression: Refactor ZipEntry creation and add FileType enum
