Support APFS

[bitigchi]

APFS is the file system used on Macs and iOS devices.

Documentation:

[1] ​https://developer.apple.com/support/downloads/Apple-File-System-Reference.pdf
[2] ​https://developer.apple.com/documentation/foundation/file_system/about_apple_file_system

(also it's not present in component list of Trac).

Apparently, Paragon released an open-source SDK, kind of like the NTFS-3G library we make use of for our NTFS driver: ​https://github.com/Paragon-Software-Group/paragon_apfs_sdk_ce

There are three caveats however:

• The library only supports APFS with read-only file system support
• The library license clause is a strange 3-Clause BSD like license
• There's a weird condition clause in the license: "Modification of the source code does not implement and/or enable APFS write functionality."

There is some code for an APFS FUSE driver: See: ​​https://github.com/sgan81/apfs-fuse

If there is already a FUSE driver, why not just port that via HaikuPorts? Do we have any particular reason why we need in-driver support?
