[Libguestfs] [PATCH v7 3/4] New API: find_inode
Library's counterpart of the daemon's internal_find_inode command.
It writes the daemon's command output on a temporary file and parses it,
deserialising the XDR formatted tsk_dirent structs.
It returns to the caller the list of tsk_dirent structs generated by the
internal_find_inode command.
