JBAS-4588; DeploymentSorter

[alesj]

What exactly does this task want me to do? :-)
- https://jira.jboss.org/jira/browse/JBAS-4588

We currently have the following configuration:
- LegacyDeploymentContextComparator (LDCC):

 static
 {
 legacyOrder = new HashMap<String, Integer>();
 legacyOrder.put(".deployer", 50);
 legacyOrder.put("-deployer.xml", 50);
 legacyOrder.put(".aop", 100);
 legacyOrder.put("-aop.xml", 100);
 legacyOrder.put(".sar", 150);
 legacyOrder.put("-service.xml", 150);
 legacyOrder.put(".beans", 200);
 legacyOrder.put("-jboss-beans.xml", 200);
 legacyOrder.put(".rar", 250);
 legacyOrder.put("-ds.xml", 300);
 legacyOrder.put(".har", 350);
 legacyOrder.put(".jar", 400);
 legacyOrder.put(".ejb3", 400);
 legacyOrder.put(".par", 400);
 legacyOrder.put(".war", 500);
 legacyOrder.put(".wsr", 600);
 legacyOrder.put(".ear", 650);
 legacyOrder.put(".jar", 700);
 legacyOrder.put(".zip", 750);
 legacyOrder.put(".bsh", 800);
 legacyOrder.put(".last", 900);
 }

 private boolean useDefaults = true;
 private Map<String, Integer> suffixOrder;
 private int defaultOrder = 850;

 /**
 * Get the instance.
 *
 * @return the instance
 */
 public static LegacyDeploymentContextComparator getInstance()
 {
 return INSTANCE;
 }

 public int compare(DeploymentContext fst, DeploymentContext snd)
 {
 int fstOrder = getContextOrder(fst);
 int sndOrder = getContextOrder(snd);
 int diff = fstOrder - sndOrder;
 if (diff != 0)
 return diff;
 else
 return super.compare(fst, snd);
 }

 /**
 * Get context's order.
 *
 * @param context the deployment context
 * @return context's order, or default if no match
 */
 protected int getContextOrder(DeploymentContext context)
 {
 String simpleName = context.getSimpleName();
 for (Map.Entry<String, Integer> entry : suffixOrder.entrySet())
 {
 if (simpleName.endsWith(entry.getKey()))
 return entry.getValue();
 }
 return defaultOrder;
 }

- LDCC is then used in MainDeployer::comparator
- LDCC is used in EARStructure::comparatorClassName
- jboss-structure.xml/context can now take comparator attribute

What else do we need?
