* Introduced dedicated syscalls for the deprecated BeOS fs_attr API. Before,

each attribute access needed 3 syscalls, now only one as it should.
* Renamed the new Haiku call fs_open_attr() to fs_fopen_attr(), and added a new
  function fs_open_attr() that takes a path (same semantics as the
  fs_[f]open_attr_dir() functions already present in BeOS).
* Merged former _kern_open_attr(), and _kern_create_attr() into one syscall.
* Cleaned up vfs.h.
