From: Filipe Manana <fdman...@suse.com>

The previous patches added support for operations to set, get and delete
xattrs on regular files and directories, this patch just adds an operation
to list the xattrs of a file/directory.

Signed-off-by: Filipe Manana <fdman...@suse.com>

V2: New patch in the series, the first version of the patchset did not include
    this patch.
V3: Simplified implementation to not need to open a file descriptor and
    use a path string instead.
