looks like getViewerUrlWithPath is throwing indexOutOfBounds exception since getViewerUrl can now at times return url that do not have a ? in it. update logic to handle that.

[FIXED HUDSON-5915] let polling save the new client workspace if it's changed, so it can check for new changes against the proper view spec.

[maven-scm] copy for tag filesystem_scm-1.7

[FIXED HUDSON-5893] always create a new XStream2 object for XMLSerializer,
do not serialize this object in build.xml (it's very large!).
This also fixes NPE loading old FSSCM builds with Hudson 1.349 or newer
where a new field in XStream2.AssociatedConverterImpl has been added.

[FIXED HUDSON-5147]: Improved documentation of useDeltaValues field.

[FIXED HUDSON-5894] avoid NPE if entry.getMsg() returns null

modernized by using HttpResponse.

- Add ClearCase report. Shows ClearCase related information:
* For builds running with base ClearCase configuration: the CSPEC that was used.
*For builds running with UCM ClearCase: the stream and baselines that were used (baselines will be shown only if CodeFreeze option was selected in the UCM ClearCase configuration).
- UCM: Implement code freeze for dynamic view. This includes adding new work flow for UCM checkout: create build stream as a child of the configured stream and use that stream for building.
- UCM: Implement clean build for dynamic view. This is implemented by removing and recreating the view on each build.
- UCM: support overriding the configured stream by STREAM parameter.
- UCM: support running concurrent builds on different streams. Implemented by dynamically allocating view name.
