- calling prebuild after build wrappers to align the semantics with freestyle projects.

build.xml that can't be deserialized

Handle resolves-to="com.google.common.collect.ImmutableList$SerializedForm"
manually and construct a suitable list. Any subsequent serialization of the
class will use the direct form of serialization.

This is a partial fix for JENKINS-10903. Any new builds will
be serialized correctly.

Based on ImmutableMapConverter.java

This reverts commit 5dce36d9
and it adds back xalan as test harness dependency

This was causing ui-samples test failure

In event-debug.js, there's an overloaded toString() method.

    toString: function() {
         return "CustomEvent: " + "'" + this.type  + "', " +
             "context: " + this.scope;

    }

When the problem happens, "this.scope" points to a DataSourceBase object, and apparently at that time this._sName is null, and it causes a failure in ScriptableObject.getDefaultValue(), at the final "fall through to error" portion (see below)

So this quick fix gets us around.

I think the root cause of the problem is that ScriptableObject.getDefaultValue() should treat null as the primitive value, but I'm bit scared to make that change right now.

Fixed the test failure. There's no beta module in YUI 2.9, and we got some old plugins that's specifying beta for modules that have graduated.

Do not class a NOT_BUILT result as a completed build when calculating
unstable/back to normal build transitions. It should be treated in the
same way as an ABORTED build.

The parent matrix build console output does not record the build status for
each job. That is useful to get a quick feel for the status of each job and
the order of execution/completion.

Matrix build tooltip reports a pending/queued build as "skipped"

The rss/atom build result feeds report status as "?"

The tooltip for the grey ball is "Pending" when it should be "Not built".

Remove excessively old change log information, replace with a link to the current stuff.
