Support recursion for applyto()

[exploide]

It would be useful if applyto() could take an optional recursive=True parameter when applying an ACL to a directory.

This could make the functionality of setfacl -R available to pylibacl.

A further option would be needed to differentiate whether following symlinks or not (setfacl -R -L/-P).

Hi, and thanks for the issue.

The problem is that the library is a) designed to mimic the C library, not the user space tools, and b) the library is written purely in C, as a thin wrapper over the C library. Implementing this feature in the C version would likely be too complex.

What could be done is to move the C library into an internal one, and write a Python "front-end" that would re-export the C library methods, either as-is, or in the case you suggest, via extended functionality. But that's a bit of a larger task - I need to think if it makes sense.

If you can send a pull request, I'd be happy to discuss and potentially merge.
