Improve extended attribute support

Mac OS X changes:
  - add support for extended file attributes via sys/xattr.h
  - when extracting an archive entry that has mac_metadata and
    mac_metadata is requested to be extracted, extended attributes
    are restored only from mac_metadata.
  - by default, extended attributes are stored both in mac_metadata and
    SCHILY.xattr/LIBARCHIVE.xattr. This is subject to review and change.

To match behavior on other platforms, store extended attributes on
FreeBSD with extattr_set_link() if no fd is provided.

Detection of extended attributes support in configure stage has been
rewritten.

Added xattr platform test to libarchive and xattrs option test to bsdtar.
