mixed priorities
General:
+28Feb09
+mvw Implemented xattr support for Solaris 9 and above and extensible
+ attributes for OpenSolaris.
+mvw Added some limits to the xattr code so that we don't blow up the
+ filed on big xattrs.
+mvw Fixed some comments which changed due to xattrs being implemented.
+mvw Changed xattr support checking in configure to test first for
+ generic solutions and when not found for specific OS functions.

mvw Don't try to copy empty jobs (e.g. with jobbytes == 0)
which gives Unable to get Job Volume Parameters errors.
