Thanks Doug.  It would be potentially useful to include the jar file in 
Hadoop releases so that there is a well-defined place for people to get 
it if they wish to use the metrics API separately from Hadoop.  Then 
again, no-one is asking for it yet.

> (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
