Add system calls to explicitly list extended attributes on a

file/directory/link, rather than using a less explicit hack on
the extattr retrieval API:

  extattr_list_fd()
  extattr_list_file()
  extattr_list_link()

The existing API was counter-intuitive, and poorly documented.
The prototypes for these system calls are identical to
extattr_get_*(), but without a specific attribute name to
leave NULL.
