SERVER-16444 Copy data in the query subsystem as needed.
A WorkingSetMember in the LOC_AND_OBJ state must be made owned when:
1. Its WorkingSetID is cached across multiple calls to work().
2. Multiple calls to next(), seekExact(), saveState(), etc. are
performed on the same WiredTiger cursor in a single work() call.
No longer necessary to always copy data out of WiredTiger buffers.
