Changes from Ant 1.10.0 TO Ant 1.10.1

Fixed bugs:

 * Ant 1.10.0 made Path#systemClasspath final which broke the Eclipse
   Bugzilla Report 60582

 * the wrapper script still didn't work on Solaris 10, but worked on
   Solaris 11.
   The "fixed" script should work in most cases but will not preserve
   newlines present in command line arguments.
   Bugzilla Report 60562

Other changes:

 * new tasks <xz> and <unxz> and resource <xzresource> for XZ
   compression. Also the compression attribute of <tar>/<untar> now
   accepts "xz" as valid value.
   The tasks and type are contained in the new ant-xz.jar and require
   the library XZ for Java to be on the CLASSPATH.
