Add time limit to locking facility
Modified the locking facility to add a time limit and remove the
callback parameter. This affected both the default facility as
well as the distributed locking feature. It will also require
a change to the rules for Closed Loop.
Changed testUnlock() to try locking with a different owner.
Default feature API should be OPER_UNHANDLED.
Put a few things back so-as not to break the drools-applications
build. They can be removed once drools-applications is updated.
Fix newlines in API java.
