suggest: speed up local rmi invoke

[steeven]

I made a 1000 loop test on local bean and RMI bean invokation:
testAccountService:40ms
testAccountServiceR:50ms
testRMIAccountService:7731ms (normal object rmi service with RmiInvocationWrapper)
testRMIAccountServiceR:1332ms (normal rmi service with Remote interface)

R means java.rmi.Remote interface.
it seemed that remoting invoke made great cost. so i think springframework should detect that whether the remoting service is located in same jvm, if true, local bean was derectly returned, else remote bean was returned.

1000 loop test:

testDirectAccountService:10 ---direct java call
testDirectAccountServiceR:20
testAccountService:40 ---factory.getBean(xxx)
testAccountServiceR:40
testRMIAccountService:7711 ---normal object's rmi service
testRMIAccountServiceR:1402 ---Remote object's rmi service
testAccountServiceHessian:4637 ---normal object's hessian service
testAccountServiceBurlap:3726 ---normal object's hessian service
testAccountServiceHttpinvoker:16744 ---normal object's hessian service
