------------------------------------------

The refactor is checked in based on local testsuite runs showing good results.  I need to add some test cases for specialized stuff.

> The EvictionConfiguration interface presumes that objects that represent a policy configuration should be able to parse their XML config themselves.  We don't want that; parsing of the legacy XML configs should be handled by XmlConfigurationParser and policy config objects should be configurable by the MC without their having any internal expectation of being passed a DOM element.
> To do this:
> 1) Create interface EvictionPolicyConfig.  This is used internally (e.g. in the RegionManager and Region classes) in place of EvictionConfiguration.
> 2) All of the config classes for the standard eviction policies now implement EvictionPolicyConfig instead of EvictionConfiguration.
> To support old custom policies:
> 1) EvictionConfiguration still exists but is deprecated.
> 2) EvictionConfiguration now extends EvictionPolicyConfig.  So, custom impls *will* need to be modified to implement EvictionPolicyConfig's 2 methods.
> 3) XmlConfigurationParser when trying to configure a policy config object will check if it implements EvictionConfiguration.  If it does, the legacy parseXmlConfig(Element) method will be called.  Otherwise it will be configured via reflection.
> Need to decided exactly how to handle the old public EvictionConfiguration Region.getEvictionConfiguration() method.
