Need to tweak a few things in the metrics package to support the Simon plugin
-----------------------------------------------------------------------------

         Key: HADOOP-204
         URL: http://issues.apache.org/jira/browse/HADOOP-204
     Project: Hadoop
        Type: Improvement

  Components: metrics  
    Reporter: David Bowen
 Assigned to: David Bowen 


(1) added an extra metrics.jar target to the build.xml so that I can build a stand-alone library
containing only the
metrics package and its subpackages.

(2) added serialversionUIDs to a bunch of classes to make Eclipse happy

(3) made AbstractMetricsContext.createRecord final, and added a protected newRecord that subclasses
can use
to customize record creation without breaking the parent class.

(4) minor fix to how errors in callbacks are handled

(5) constructor in MetricsRecordImpl made protected rather than package private so that it
can be subclassed

(6) extended Util.parse(String serverSpecs, int defaultPort) to handle the case of a null
serverSpecs by defaulting to localhost
